Using Agilent 34970a DAQ with 34901a 20 channel multiplexer to measure voltage

[mahen15385]

Hi,

I am trying to measure voltages from mulitple channels using agilent 34970a DAQ with 34901a 20 channel multiplexer through a GPIB interface. I am sourcing voltage and measuring voltage. I would like to know if there are any labview programs that are already available for use.

Thanks,

Mahender

Sure. Go to Tools>Instrumentation>Find Instrument Drivers.

(I could have given you the direct link but you should understand how to do the search yourself and you should also visit the instrument driver main page to understand what a driver is and how to use one.)

Hi,

I am using the program "agilent 34970 advanced scan.vi" that I downloaded from the instrument drivers page with slight modification on the output side for which I have attached the image below. I am getting an output from different channels row wise which cannot be used to generate plots. Can anyone suggest me modifications to get data column wise for different channels. 

I have attached the image for output as well.

Thanks,

Mahender.

The while loop in the middle of your block.jpg file is actually manipulating the string that is returned from your instument. You want to use the String and File IO palettes to manipulate the string the way you want. I would recommend copying that while loop and the Write to Spreadsheet VI to a new VI. You can use this new VI to experiment and tweak the string manipulation in order to suit your needs.

Cheers,
