I am using Keysight PNA-X Network Analyzer, N5245B to capture data. I can load .csa file, but do not know how to query current .csa file.
Unfortunately, the VNA firmware does not keep track of the name of the last state file loaded (at least not in a way that is exposed in the remote API). The VNA application does not follow the document view architecture. the VNA is a state machine and when you load a .csa (or any other state file), you are just instructing the instrument to go to a particular state, but after loading the file if you interact with the instrument, then the state changes. therefore knowing what file you loaded may not guarantee that you are in a known state.
That is a long way of saying no, but hopefully the details help you understand our reasoning behind this decision.
Are you asking if the state and calibration data is given some internal name on PNA-X?
I want to query the .csa file under current use before I make my decision to load or not a new .csa file. If the current under use .csa file is what I want, I do not need to reload it.
Wow. I was supposed to have capability to query it since the current loaded .csa file name is shown on on right-upper corner of the screen.
