Dennis,

I'm sorry I cannot find Measurement and Automation Explore in MAC. Thanks anyway!

Hi John,

You cannot use Measurement & Automation Explorer on a Mac. Use the following KnowledgeBase to access the NI 488.2 Interactive Control.

How Do I Find GPIB Devices With NI-488.2 for Mac OS X?

You are receiving Error 1073807202 because you do not have NI-VISA installed or there was an error in installation. You can install NI-VISA from the link below. Please check the readme to make sure the operating system and LabVIEW version is compatible with the driver version.

Thank you,

Hi Simran,

Thank you very much for your suggestion!

I don't have "Interactive Control" option in my NI-488.2. My system is MAC OS 8.1. I have a NI-488.2 Test. Is that the similar function? Thanks

Hi John,

What version of NI-488.2 are you using? Try downloading version 7.6.1. Also, can you please give me some information about NI-488.2 Test?

Thank you,

Hi Simran, I'm sorry to response so late. I took a vacation. My NI-488.2 version is 7.6.3 and NI-488.2 version is 7.1.2 I'm trying to install NI-Visa. I found a software named NI-VISA 2.6 Runtime which is match our system. Is that correct?

Hi Simran and Dennis,

We figure out the reading problem. It is address conflict (two meter shared the same one address)! Thanks for your efforts!

Hello

I have a problem with my 34420A. I use the driver that you put here and works fine, what I want is to know the string command that I have to send to select the both channels (Ch1 and Ch2 at the same time).

I look in internet but don´t find a document that tell me any string command to send to the 34420A nanovoltimeter, the commands that i´m talk about are like " :TRIG:SOUR IMM; or :READ?" if its possible to help me to know the command to select the both channel I apreciate.

PS - I work with labview for windows not for MAC. 

Regards,

Ricardo Gomes

Hi Ricardo,

I think you may use concatenate strings to combine "rout:term fron1" and "rout:term fron2". The program is enclosed.

Good luck!

John

Where did you look on the Internet? All you had to do was go to the manufacturer's web sit (www.agilent.com), search for 34420A, and download the manual.

I took a brief look and I don't think it is possible to select both channels for a simultaneous reading. You can give it a more thorough read and if necessary, contact Agilent to ask about the capabilities of their instrument.

Hi Dennis,

You are right, it is impossible to read both channel simultaneously. But if he/she want to measure voltages through the two channels, it is possible to do it within a second.
