May be you can extend the time base until you capture the periodic 100Hz ripple?;) --- End quote --- I got nothing. On the Siglent or on my old school analog Tek 475. If I extend the time base to 2mS to match your capture, that brief pulse I showed just gets lost in the noise. The only way I can track it all the way to 2mS is to set the triggering to trigger on that specific pulse AND to use averaging to minimize noise. It seems to have a weird period of 68.5 Hz. It is definitely caused by the Kunkin; it disappears when the unit is powered off, appears at about the same point the boot reaches the model/version/ID splash screen and is there independent of whether the load is on or off. --- End quote --- Well, that is interesting! I can’t even explain where this pulse comes from; weird :) |
