I am having trouble programming a PXI 1078 with multiple NI4145 SMU's with a trigger waveform from an EXFO tunable laser output. The laser outputs a trigger trace correlating to each step of the tunable laser as it scans wavelength. I am using one NI4145 as the trigger input. THe trigger signal is a 10 KHz, 2 volt, 100 us period. I want to use another NI4145 to apply a 2 volt bias and read the current at each trigger pulse. I will attach the trigger signal and the Labview vi I have so far. I have tried many variations and still cannot seem to get this right. Any ideas will be appreciated.
