Overloading
At a reference level of -10 dBm and at an external generator output level of the same
value, the R&S
FSW operates without overrange reserve. That means the R&S FSW is
in danger of being overloaded if a signal is applied whose amplitude is higher than the
reference line. In this case, either the message "RF OVLD" for overload or "IF OVLD"
for exceeded display range (clipping of the trace at the upper diagram border = over-
range) is displayed in the status line.
Overloading can be avoided as follows:
●
Reducing the output level of the external generator ( "Source Power" on page 396
in "External Generator > Measurement Configuration")
●
Increasing the reference level ( Reference Level in the "Amplitude" menu)
8.2.4.3 External Generator Control Settings
Access : [INPUT/OUPUT] > "External Generator Config"
The "External Generator" settings are available if the R&S FSW External Generator
Control option is installed. For each measurement channel, you can configure one
external generator. To switch between different configurations, define multiple mea-
surement channels.
For more information on external generator control, see Chapter 8.2.4.2, "Basics on
External Generator Control" , on page 382.
