Power levels for low frequency signals not correct
By default, the R&S
FSMR3 uses AC coupling for RF input. For very low frequencies,
the input signal may be distorted with this setting. In this case, use DC coupling
instead. To change the setting, select "INPUT/OUPUT" > "Input Source Config > Radio
Frequency > Input Coupling > DC".
Invalid trace display
If output to the "IF
2
GHz
OUT" connector is activated, the measured values are no
longer sent to the display; thus, the trace data currently displayed on the R&S
FSMR3
becomes invalid. A message in the status bar indicates this situation.
Web browser access to instrument fails
If an error message ("Failed to connect to server (code. 1006)") is displayed in the web
browser instead of the instrument's user interface then the LAN web browser interface
was probably deactivated.
