Missing digital scope when using unusual time base

[zelle]

Here is the procedure to reproduce:

• define a pattern, e.g. custom pattern for DIO 0
• take a single measurement with analog signals and activated "Digital" scope to show defined pattern
• digital pattern is shown well as long as provided time base value is used, e.g. 100 ms/div
• change time base to unusual time base, e.g. 150 ms/div
• analog scope and digital scope is adapted to this new time base
• take a new measurement with this selected time base
• --> analog scope is shown well but digital lines are missing!

Is there a technical reason why digital lines cannot be measured with such time base?

Tested with Version 3.21.26 (beta)

Hi @zelle

With odd base the digital can be auto-set to lower rate than the analog and it takes more time for the digital to complete the capture. At higher base this difference can be significant and the instrument does not wait for the digital capture.
Thank you for the observation. It will be fixed in the next version.
(The bug was introduced when adding dual device support.)
