I am using Keithley 2601A and feeding TSP files directly to the machine through GPIB connection. 

I want to do an IV pulse sweep where I output voltage and measure current. There is an already existing function in the machine "ConfigPulseVMeasureISweepLin()" and "InitiatePulseTest()" that does almost exactly what I want. The problem is that allowed total time is limited. I want to be able to run longer measurements than allowed. 

I couldn't find code version of these functions so that I can do the changes I want to make. Is there a way to overwrite these functions such that I can run longer pulses? Or is there an code version of these function somewhere?

Thanks in advance for any kind of help.
