Two Scopes simultaneously

Post by david.p »

Hey,

I was wondering if it is possible to adress to scopes simultaneously, with the same settings, in C. I got two 5443B here and I was experimenting with the C code driver example the last time. I was able to hardcode an export to CSV data and the triggersettings for the scope already, but for my project I need to take measurements both scopes at the same time, with external trigger source.

So far there are two options I consider:
- Hardcode one device per program and open two terminal sessions
- Fix the code to adress two scopes simultaneously

Do you have any suggestions ?

I should do the last one, just because it is more fun to do :D

Be aware that if you want synchronous data for both scopes you need to trigger both of the scopes with the same signal, so the signal that causes the trigger should be connected to both scopes.
The result of this is you have 1 chanel less data than the sum of the channels on both scopes.

P.S. what is the sample rate (samples / sec) you want to use.

I would definitely be looking at modifying the code to address two scopes, it is a relatively straightforward exercise :)
