Hi nolsqn,
Unfortunately, I am unable to see the missing VIs from Keithley, but from what's left of the code, I see that the OLWrite VI is very similar to our DAQmx Write VI. Although my knowledge of Keithley's programming VIs are limited, I believe the problem may be with how you are passing the data to your OL write. I see that you kept your data as a complex double. Could we try and see what would happen if we changed the data to an array of double. If this works, you may want to separate both your real and imaginary components and make them into an array as Dennis showed in one of the previous posts. Also, if you decide to write to more than one channel, don't forget to include both channels on in your channel name.
