Seeking examples of continous data acquisition from multiple instruments

[wittyname]

Can someone point me to examples of acquiring continuous data from two instruments? I was acquiring the output from a power meter but now wish to integrate the signal from a HP DMM, plot current vs power as it runs and then generate a report. I'm interested in technique. Do I sequence them in a loop? Do I just run them in parallel? Synchronization methods?  It seems that there should be plenty of examples of multiple instrument data acquisition but I can't find anything useful. I am using LV8 and GPIB.

Thanks

Hi

Measuring two or more instruments over gpib can be done in different ways.
If you need exact timing (triggering on the same moment) you need to arm the instruments and trigger them together and after that read data from the instruments in any order.
If you are not time critical, you could do it in a sequence but instead of using sequence frames use the sequence by wiring by using the error in / error out wires.

I would not address the instruments in parallel, You should prevent race conditions.
Best non time critical approach seems to me write A, write B, read A, read B.
