asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that?

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that?

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that?

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

asked Siglent support but after a couple of responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!

responses the thread went cold. Maybe I’m being dumb but I’ve noticed that there’s a frequency (low, around 100Hz) where scope response changes a bit. Below and above it square input looks square. Right about it square input looks slanted.\n \n I tried to do a very slow “sweep” and there’s small but visible change in the envelope. So, e.g. with a constant 600mV p2p input lower frequencies measure exactly that while higher ones measure 612mV, so ~2% diff.\n \n Terminated 50Ohm cables (not that it matters at such a low freq) to be sure. Latest firmware, after full self-cal. Siggen itself seems allright, I have an ancient Tek scope and the siggen output looks Ok there with same input/same cables. Scope seems happy and fully functional otherwise, few years old though, out of warranty.\n \n Has anyone else seen anything like that? Is this a normal behavior within the expected margin of error?\n \n Thanks!
