I had a strange thing happen with the P6403 scope and Picoscope 6.4.64.0 SW.

The sample interval started at 800 psec at the beginning of the waveform and then degraded to 8 nsecs towards the end of the waveform; in the same waveform !

Can I change my setup to eliminate this behavior, or is it a possible SW bug ?

Thanks,

That is strange, could you send me your settings file?

Kind regards

I just re-looked at the data.
The problem seems to occur when my zoom is => 131K
and I'm looking at data in the last 1/3 of the waveform ?

My Collection time = 10 ms/div
No of samples = 200 MS

Sample interval = 800 ps
Sample rate = 1.25 GS/s
No. os samples = 125,000,000

I included the setup with no waveform data.

Thanks,

Hi I opened the file but could not recreate your problem. Does this happen all the time?

Hi how do you know that the sampling interval has changed, is this because you used the rulers?

Kind regards
