Hi,
Recently I upgraded my Siglent 1102CML with new firmware 5.01.02.32. The main reason was that for single mode I could not enable LongMemory depth. Even I enabled it before, once I pushed Single button it returned to normal mode immediately. Now this works fine. Unfortunately when I scale time base to about 5ms, capture a single shot and then scale to 2,5us the display shows vertical stripes. When scaling deeper it even gets worse. If I change display mode to dots instead of vectors the display is correct to about 250ns. Then the waveform gets flat (GND).
Has anyone else encountered the same problem? Please check with your scopes.
It would be also nice if Siglent could investigate this issue. I can support with data logs/pictures, whatever is needed.
Regards
