While switching to " Nose Figure Setup" or "Noise Calibration" window, an error message pops-up with "Error: ECal codes for model N4691-60009 are missing" . It blocks Noise Figure measurement class application.(N5242A rev 10.64.09)
But this Ecal works well for GCA measurement class, and no problem for standard 2 ports Calibration.
This is a bug, but it can be fixed without a firmware change in the short run. Here’s how to do that:
• Navigate to the ‘C:\Program Files (x86)\Keysight\Network Analyzer\Noise’ directory (in older PNAs the directory might be Agilent instead of Keysight).
• Open the file ‘ecal_states.xml’ with a text editor.
• After line 42, add this text:
<model name="N4691-60009">N469X</model>
The exact line location isn’t important, but it should be near the other N4691 model entries for clarity.
Restart the PNA application, and the error message should not appear again.
