I noticed your website has a big banner saying "PicoLog6 now supports PicoScope oscilloscopes" so I downloaded PicoLog6 and connected my PicoScope 2205MSO. Then I got a message saying this model is not supported! If PicoLog6 doesn't support your full oscilloscope range, I suggest you make it clear o...

Persistence mode doesn't seem to work with the 2205MSO. Things are fine in scope mode, but when I click the "persistence mode" button I get a blank screen and the message "Waiting for data..." which persists indefinitely. Sometimes attempting to go back to scope mode crashes PicoScope6. PicoScope® 6...

I was also looking for the ability to measure the time from an edge on channel A to an edge on channel B, and was disappointed to find that such a basic feature was missing. More specifically, it's the ability to gather stats on the time that would be useful, for example to evaluate the jitter of a ...

Martyn,
Any progress? Is it going to be fixed?
Rgds, Ben

Yes, you're right, it's not really a problem with pulse width measurement - it looks more like a missing samples / incorrect timebase kind of thing. In retrospect my choice of subject description wasn't very good. Unfortunately it's the best PC I have available, so trying a faster one isn't an optio...

Oops, that last link probably wasn't public... try this one:

I wasn't able to attach the files as they were rejected as too large (sigh). So I have put them on Google drive:

Martyn, I re-ran it at 100ms/div (m_100ms_div.psdata) and 200ms/div (m_200ms_div.psdata). As before, the results were correct for 100ms/div but wrong for 200ms/div. I turned off the digital channels and tried again at 200ms/div (m_200ms_div_digital_off.psdata). This does seem to fix the problem. I'v...

Bennog,

Thank you for suggesting that topic, but no, it quite obviously does not explain the differences I am seeing.

Ben

Martyn,

Yes, if I change the slow sampling transition to 500ms/div, then the measurements are good at 200ms/div. So it appears there is a bug which only affects slow sampling mode - do you agree?

Thanks,

Ben

Bennog, Thanks for pointing this out, but I was already aware of it. The thing is, I'm seeing good accuracy at the lower sampling rate, and lousy accuracy at the higher sampling rate. At 12.27KS/sec you'd expect to measure a 500ms interval to about 0.02% accuracy. At 2.5MS/sec, you'd obviously expec...

I have a circuit which generates an accurate pulse 500ms wide. I use the PicoScope 6 measurement function to measure the high pulse width between rulers. When the timebase is set to 100ms/div, I get sensible results: Min=500.1ms; Max=500.1ms; Average=500.1ms; sigma=24.46ns If I change the timebase t...
