Getting Keithley 2000-20 data faster (SCPI)

Post by krambambuli » October 19th, 2021, 10:04 am

We are asking our Keithley 2000-20 DMM with multichannel card via SCPI successfully for data with the RS-232 interface. Unfortunately, we just can get 3 values per second of channel 1 (3Hz). If we are asking the device for more than 3 values, there will be an error code on the display and a beep sounds (different baud rates are already tested without any effect).

I tested different SCPI commands. Here is my current code (VB.NET):

SerialPort1.WriteLine(":ROUT:CLOS (@1)")
SerialPort1.WriteLine(":FORM:ELEM READ, CHAN, UNIT")
SerialPort1.WriteLine(":MEAS:VOLT:DC?")


Is it possible to get more than 3 values per channel from the device? We want to get as many values as possible of channel 1 (DC voltage).

Best regards!

I think I found a good way to collect the data completely (Keithley 2000 data logger): http://it-experience.xyz/index.php/en/d ... a-loger-en

it's working good and very fast :)
