I am trying to measure/record temperatures using Agilent 34901A and 34970A. I have all the T type TCs connected. I am not familiar with Agilent drivers so if anyone can provide some guidance. I just need simple VI. I am familiar with typical DAQ Assist VI and acquire signal from NI Hardware but no experience with Agilent. I got the drivers for Agilent but it seems much more complex than I need it to be.

I have been messing with a variation of Agilent drivers for the last couple of days. Labview's built in Visa drivers don't handle Agilent stuff quite correctly, and so you need to install their driver version (with the Agilent IO Libraries Suite). There is lots of documentation showing you how to configure LabVEW to work with their Visa drivers. Once you get that taken care of, I'm sure there are sample programs you can model off of. For example, try here:
And don't forget to apply the thermocouple coeffecients in to your program if you scan the voltages directly 🙂

LabView has no problems with NI-VISA and the Agilent 34901A.
For quick and dirty thermocouple measuring I suggest you look at the Initialize and EZ-Config to start with.
For best results you need to take several steps.
Configure the communications
Configure your channels for measurement type
Configure and build a scan list
Scan the channels each time you need a reading
