keithley 2400 SCPI commands for Measurement Speed

[Ryien]

Hi,

I am using Labview 2012 and Keithley 2420 to measure Current Response Time (Current output vs. Time) for our solar cells. I downloaded the template on keithley's website for I-V curve but modified the SCPI command parameters slightly to increase the sampling rate.

However, even with the settings now, I am only still recording 60 points / sec. After saving the code, I have another event that reads it at 256 byte. Also, when I set "TRIG:COUNT 100+" i get an error -410 about queries.

Is there a way to collect more points per sec than this? I read that the keithley 2400 can record up to 1700 points per sec.

Unless the problem lies within my Labview code and not the SCPI command?

Any help would be appreciated! ( i have attached an image of the SCPI command below):

Here is a more complete simplified version of the code structure with the SCPI command. It is still only recording about 60 points per second.

Hi Ryien,

Thank you for contacting National Instruments regarding your Current Response Time system. Have you downloaded the full set of Keithley 24XX Examples? If so, which particular example are you working with?
