Just got my hands on DDiscovery today. Hoping to use it to replace my bulky old logic analyzer for testing my Analog-to-Digital Converters.
Initially, I apologize If I tend to write more than I need to.
I would like to have the below three functions simultaneously in the Logic Analyzer tab.
1) Synchronous with external clock: To capture 16+ channels using an external clock which would be a DATARDY flag or just sampling clock from my ADC.
2) Trigger-based acquisition
3) Repeat it for number of times while saving to file each time.
So far, in Waveforms, I can only get 1) without 2) or 3) and vice versa.
So basically, I want :
1) Wait for Trigger
2) If Trigger, start a "SYNCHRONOUS" acquisition
3) Once complete, save to file.
4) If total number of acquisitions not complete, Go back to 1)
In Waveforms, if I go to "SYNC" mode, the "trigger options" become disabled. If I go to repeated, it is not "SYNC".
To sum up,
1) Can I, using Waveforms, get the above working?
2) If not, is it a hardware limitation? or is it just software. If software, can I write my own script to build the above scenario? Note I am not a software guy, pure analog so will be a big thing for me to get familiar with Java scripting stuff.
Sorry again for the long question and thanks in advance.
