I am working with an N5224A with firmware A.09.50.08.
Our automation software connects and issues the following commands:
*OPC? (and it says +1)
This used to work. We sent out the NA for calibration and when it came back the last command DISPLay:WINDow1:TRACe:NEXT? times out, even if I set the timeout to something like 20 seconds.
Also, the response to CALC1:PAR:CATALOG:EXT? comes back "NO CATALOG" when it used to have contents after issuing the FPRESET.
FPRESET is supposed to put the instrument in a known state, correct?
Why would this be?
