How do i use credentials for my instrument connection to setup a device password

[MalteGS]

Hi!

We're planning an architecture rearrangement to our test setup as we are planning on moving soon and I'd like to test how to lock instruments using credentials. I've managed to find this document(https://lxistandard.org/Documents/Articles/IviSecurityFeatures.pdf) talking about the use of "CredentialInformation" to connect to a VISA device but I've been unable to find any documentation on how to accomplish this. The current instrument I'm testing this on is a Rigol DP832A and for this instrument I'd like to figure out the following.

How do i set a password/credentials for the instrument?

What does the connection string used to access a password protected instrument look like?

Are there any other things i need to do in order to ensure no accidental connection to the test instrument?

Thanks in advance

Existing measuring instruments have no concept of security.
Once connected, anyone can control anything.
It seems that the concepts of authentication and encrypted communication (TLS) first appeared in HiSLIP 2.0, but I have never seen a measuring instrument that is compatible with HiSLIP 2.0.
Even the conventional HiSLIP 1.0 is not supported by many measuring instruments.
Also, NI-VISA does not support HiSLIP 2.0.
Keysight VISA (IO Libraries Suite) + Keysight Secure Instrument Communication Expert is required to use HiSLIP 2.0.

That is unfortunate to hear.

But thanks for the quick and detailed answer!
