VISA resource Agilent 34980A

[Zuc_lab2]

Hi,

In my application (LabVIEW 2019), I need to manage both generation and measurement of an Agilent 34980A. I have searched around and I found only a little about the integration between the device and LabVIEW. However, since in the error buffer I have found the “+350 error: queue overflow” I have thought that two command at the same time are bad managed by the device.

So is there anyone who has already dealt with this problem?

In analyzing the VISA commands I have found this “duplicate session” parameter that I do not get if it can be helpful or not for my aim, since it only says: “If duplicate session is TRUE and there is currently a session opened to the resource, another session is opened to the resource. If duplicate session is set to FALSE and a session is opened to the resource, the open session is used. A VISA session is a unique logical identifier used by VISA to communicate with a resource. The VISA session is maintained by the VISA resource name control and is not seen by the user.”

Thank you for the help!

Best regards,

Zuc

Hi,

It seems that a driver is available for this instrument : https://www.keysight.com/us/en/lib/software-detail/driver/34980a-multifunction-switchmeasure-mainfra...

For the VISA duplicate session = true, it will just create a new VISA session if you recall VISA Open. It doesn't seems useful for your case, it can be used in case of re-init or just close, clear error and re-open session. But anyway, there is a driver.
