CRDS Triggering #118

Closed mcotterell closed 7 years ago

mcotterell commented 8 years ago

The CRDS waveforms do not appear to be triggering correctly in UI, but still recording correct tau values. Interestingly, triggering seemed Okay when frequency was reduced to 1000 Hz from 1500 Hz, but issue there when frequency increased back to 1500 Hz. A system restart seemed to help, but the issue re-emerged later on in the day.

Perhaps I should have put ticketed this as a server issue?

lo-co commented 8 years ago

Probably. For right now it is best not to play with the frequency. The frequency should sit at 2 kHz and remain. We have been successful with this over the past couple of weeks so I suspect this is an issue with changing the frequency.

There are two issues (lower priority) that should be raised in relation to this:

provide flexible duty cycle
robust response to changing frequency

This looks like this is directly related to msr-consulting/exscalabar_server#159. This should probably be closed and fixed on the hardware side. Will leave this open to verify this is not an issue solely with the UI.
