Hi @ps_Water and thanks for following up! I did capture the 10 kHz file that is 36 GB and 237642 seconds (2.75 days) long. When I first open it, there is no progress bar. It takes 1:45 minutes to display a reduced-resolution waveform, and 2:30 minutes until the normal resolution waveform.
If I zoom into a 1-second window around 201015 seconds, it takes 41 seconds to display the normal resolution waveform, again with no progress bar. If I add dual markers and then right-click the marker, select Analysis → Histogram, it takes 3 seconds before the “Histogram configuration” window appears. After pressing Ok, the progress dialog box does appear, and the Histogram appears about 3 seconds later.
Now, if I zoom out and then zoom in to another place, drop dual markers, and select Histogram analysis, all before the waveform updates, then the “Histogram configuration” window takes longer to appear, again without a progress bar. If I am impatient, it seems that starting histogram analysis too soon stops the waveform update and then never displays the “Histogram configuration” window. I believe that this successfully duplicates what you reported, and it is repeatable.
For the time being, the workaround is to wait for the waveform to update before running any of the analysis tools. Since the UI does not have a progress bar, you can use “Task Manager” on Windows to see when the CPU utilization for the Joulescope UI drops to 0%.
Based upon the findings, I created the following issues:
- JLS performance is too slow. See Issue #102.
- Analysis fails when JLS read updates are in progress. See Issue #103
Thank you for reporting these issues, and the plan is to fix them in the next software release.
