Remote command:
Setting the Reference Level Automatically (Auto Level) ← Reference Level
Automatically determines the optimal reference level for the current input data. At the
same time, the internal attenuators and the preamplifier (for analog baseband input:
the full scale level) are adjusted so the signal-to-noise ratio is optimized, while signal
compression, clipping and overload conditions are minimized.
In order to do so, a level measurement is performed to determine the optimal reference
level.
This function is only available for the MSRA/MSRT Master, not for the applications.
You can change the measurement time for the level measurement if necessary (see
"Changing the Automatic Measurement Time (Meastime Manual)"
Remote command:
Full Scale Level Mode / Value
The full scale level defines the maximum power you can input at the Baseband Input
connector without clipping the signal.
The full scale level can be defined automatically according to the reference level, or
manually.
For manual input, the following values can be selected:
●
0.25 V
●
0.5 V
●
1 V
●
2 V
If probes are connected, the possible full scale values are adapted according to the
probe's attenuation and maximum allowed power.
For details on probes see the R&S
FSW I/Q Analyzer and I/Q Input User Manual.
Remote command:
5.4.4 Frequency
The center frequency of the input signal is configured in the "Frequency" tab of the
"Input/Frontend" dialog box.
► To display this dialog box, do one of the following:
● Select the "Input/Frontend" button in the Analog Demodulation "Overview" and
switch to the "Frequency" tab.
● Select the FREQ key and then the "Frequency Config" softkey.
