[Premium-Rx] R&S EK56

[Paolo Mantovani]

Hello everybody,

I have recently acquired a R&S EK56/4. Does anyone in the group have 
experience with it? I suspect that the AFC function is not working 
properly. Not sure what the proper behavior is supposed to be, however 
in USB mode, if a signal is correctly tuned with AFC off, when I turn 
AFC on the same signal gets tuned off by approximately 1kHz below the 
correct frequency. Any help would be appreciated.

Regards
Paolo
