Test and Measurement Forum

Hello Ziko,

I sent you some emails last week regarding this issue. I included a trace link. But I didn't receive any reply. Did you receive the emails?

Any news about this issue?

Today I downloaded the versions R6_2_20 and R6_3_26.

Version R6_2_20 still crashes on startup with Windows XP SP3. Version R6_3_26 works with Windows XP SP3!

But all other problems remain in both versions. Softwares crashes when:

* export the reference data
* convert to .csv
* setup the Advanced trigger in the LOGIC option

Hi,
Sorry for t he delay in replying, Ziko has been out this week. Recent releases have been brought forward for other reasons and may not address these concerns completely.
From my testing here, both new versions 6.2.20 & 6.3.26 start OK in Win XP SP3.
Reference wave forms only fail if you have a huge number of samples (uses up large amounts of memory).
CSV save works for me (as long as you use consecutive channels, don't miss out one, like A,B & D)
Yes, Logic setting in Advanced trigger causes a crash, we are working on that.
Please email support@picotech.com if you feel any of the above is wrong, I will feed that over to software.

Hi Peter,

Thanks for replaying. Here only version 6.3.26 starts on SP3 in 3 machines.
But we have machines with SP2 and we tested the version 6.2.20 on them.

The traces are big(about 20MB file). I sent one of the traces to Stuart. Did you test it? Try to export or use it as reference. We just need a solution for this right now, because we need to work on these traces and we can't export them or analyze them using reference, because the software crashes!!
Please test the trace I sent to Stuart and let me know.

Hi,
Reference waveforms were never intended to be that large, they were for direct visual comparison. By the time your waveform is expanded to see each individual bit, the zoom level is so high as to make visual comparison impossible. Again, export to Excel via a .CSV file gives a huge amount of data. To view your waveform you can re-load into PicoScope6 and to save it for external analysis you can export it as a Matlab 4 binary which has no limitation of length. We are looking at making PicoScope6 handling larger files but these is a limit.

Hi Peter,

So what can I do? Can I crop the big wave forms I have and save them as smaller files?

Someone please help me!!

Hi,
You have recorded very large files with a large amount of data. There is no way to process them after saving to reduce this. Our .psdata format was designed to cope with very large files and be able to reload them into PicoScope6 for close examination including multiples levels of zoom. We employ a large amount of compression to keep the file size small. Conversion of the raw data into other, uncompressed formats will make even larger files which few 3rd party programs can handle. You can convert to a Matlab4 (Binary) file and extract from that.

Ok, but we can't use MatLab to work on them. We need to export them to CSV or use as reference in the picoscope software as we cannot log them again.

What should I do? Will you fix the software soon?

Hi,
What do you actually need to do with the waveforms? You can't load them back in as reference waveforms but you can re-load them to view again just as they were originally shown. Are you wanting to do a bit by bit comparison with another waveform?

PeterF.

Hi,

We need to compare the waveforms we already have.

Nothing yet?????

Hi Marcus,

The next software release will have some fixes for the reference waveforms as per email.

Kind regards

Hi

This is a bug-report. I am using PicoScope 6.3.43.0.

When I try to set up the 'logic trigger' with a trigger condition on A and B the with some levels, the levels are changing although I do not enter new numbers in the edit boxes.

This bug should be (all too) easy to reproduce.
