Keysight 34461A Write block error

[UbaidAkbar]

Hi everyone,

I'm currently working on initializing a Keysight 34461A Digital Multimeter (DMM) using only VISA and SCPI commands. I've created a block intended to be used during the initialization phase of a state machine.

However, when I run it, I encounter an error in the VISA Write block. The error code I'm getting is:

-1073807360

I've looked into this extensively and tried several potential solutions (including those suggested by ChatGPT), but unfortunately, none have resolved the issue so far.

Has anyone experienced this error before or have any insights into what might be causing it?

Any help would be greatly appreciated!

Thanks in advance.

Make sure every VISA Resource you open gets closed when you are done with it. The VISA Close.vi is on the VISA -> Advanced pallet.

Hi Jeremy,
Thankyou for the reply. Adding close block means do I have to add close after every section lets say 
Write-Close
Read-Close 
or only one close at the very end of the block?

You open once at start and close once before end.

Typically there is a loop in between where you read/write multiple times…
