Agilent 34461A controlled with Labview

Hi,

 

I need some support from the you in regards to a problem that i have when I'm trying to communicate with an Agilent 34461A using labview.

I am using the examples from labview and when i run the application the DMM goes into remote state but everything freezes.

Even if i try to abort the execution is not doing anything. 

I think I have everything installed and I also did a firmware update to 2.17 version on the agilent which is the latest.

I have downloaded the Keysight benchVue just to validate the cable and USB port and with this is working fine.

Please see attached screenshots from MAX with all the SW, Labview with the diagram and from BenchVue wit hthe measurement taken.

 

What else should I try to acquire data from the DMM?

 

Thank you!

As the BenchVue software is simply sending SCPI commands, you can do the same. 

The 10MOhm impedance plus Auto Zero settings have there default settings for DC Measurements.  All you need to do is send the following:

MEAS:VOLT:DC? 10

The 10 implies the 10 Volt range for Vdc measurement.  There is no entry needed for the 10 NPLC as that is the default.  Use this simple VISA vi to perform the task.
