Anritsu FAQs
I am attempting to set the discrete frequency sweep on my MS4624B VNA. On occasion I will receive the message "DISCRETE FILL NOT ALLOWED" when I try to set it via the button sequence: FREQ->DISCRETE FILL after defaulting the VNA I can do it without problem, which leads me to suspect that there is another setting that I have set that prevents this. What other configurations on the VNA would prevent me from setting the discrete frequency sweep?
There are several conditions that will bring up the "DISCRETE FILL NOT ALLOWED" warning. The most common is when there is an active cal on. The customer should set up his frequencies prior to calibrating and with any previous calibrations turned off. This warning is to prevent the user from selecting discrete frequencies that do not have associated cal data.
