    Im using the BNC off the sunmoon, Last time I tried the probes that came with the unit, I got the same results.

    I will try again.

    Something's up for sure - the first shot is about right to test to ATX spec, except the waveform is way out of spec. I too wonder about the probe technique.

    What rail is it measuring?

    Edit - I see, the BNC is being used. Anything else on the AC line interfering? We have a TV set here at the house that knocks everything askew when turned on.

    I know whenever I have my wall power coming from my Toshiba 10MW 4S reactor system instead of the city mains, I get readings that are out of whack.

    * It's a joke.

    I hear they finally fixed that problem with the Series IIB. Of course, that'll cost you another million five for the line filtering option

    a little better, But I had to ramp up the voltage to keep up with it.

    Have you tried in the mS range yet?

    I have similar problem. Don't know why switching noise went so wild. On some units it's no more than 50mV, on others, maybe right at 120mV, maybe 200mV or higher.
    I'm using BNC. I don't know if it has something to do with impedance matching.

    Maybe you encounter the same problem like this guy.

    Thanks. Today I had a great discovery. I'll do some experiments before going into a conclusion, but it looks like I found the problem.
