But it would slow the rate considerably. The internal sweep feature where you could get this pulse always stores the data into the buffer.
Then you have to get the data out after the sweep.
But, if you want to, you can use SCPI commands to set a voltage value, take a reading and then set the voltage value to zero or negative or what ever you need and do it again. You could do this in a loop.
This would have a lot of GPIB communication and would slow it down.
With the internal sweep mode for pulsing yo ucould get probably 500Hz(maybe).
With the SCPI commands in a loop you could maybe get 100Hz?
These are just estimates.
Thanks so much for the reply. As far as the sampling rate goes, I only need to take data at about 200mHz so using the internal sweep method seems like it will work just fine. I am however having trouble syncing all of my measurements together in Labview. I am taking some data using a NI DAQ which has it's own internal timing, and shows my data in real time. However, I am not exactly sure how to display data taken by the Keithley on a similar timing clock. Also, is there a way to change how much data is stored in the buffer and when it will out put? For example, if I am sweeping from 0 to 1V, can I empty the buffer every 200mV or do I have to wait for the entire sweep to be completed before seeing the data?
