I want to record data using SR830 for time (say 't' minutes) and pause the recording for some user defined time (say 't1' minutes). The SR830 driver does not seem to use FAST2 command and does not have any provision to do such time lapse data acquisition. I am not able to get it going with the FAST2 command. Has anyone done such type of time-lapse data recording(continuous data recording with in-between pauses until user stops it from front panel) ? Can someone please help me to code this?
