Hi everyobody. I am new with programming in LabvView. I have made a program to control my Keithley 237 with LabView. I use an Agilent 82357A to control the Keithley. So far I havent had any succes in communicating with the device. As far as I understand, the way I must communicate with my Keithley device through the Agilent 82357A is by a VISA protocol right? I am able to make that LabView and MAX detect the Agilent Card, and now the VISA Address from my Keithley is available to be used in the LabView. However, when I send the typical comands such as Reset, or Set Voltage to the Keithley through the VISA Send command in LabView I get back some errors.
I would beglad if you could help me in some way.
Greetings,
Luis.

I am not really an expert at Labview or the Keithley 237. You do need to use the VISA protocol to communicate so you would need to open a VISA session and then use VISA reads and writes to communicate.
Are you able to communicate with the Keithley 237 in MAX? Have you tried using NI Spy to see what is going on over the bus?
Do you have the Agilent IO Libraries installed? It can be installed side by side with NI VISA. I have never used my 82357 with NI VISA. That might also help.
Thanks,
Matt
