R&S FSQ Signal Analyzer - Rohde & Schwarz

R&S FSQ Instrument Functions
Analyzer Mode
If only one line is active, the F1/T1 line is used as the lower limit; the upper limit is
the stop frequency. If F2/T2 is also active, it defines the upper limit.
Remote command: CALC:MARK:X:SLIM:LEFT 1MHZ
CALC:MARK:X:SLIM:RIGH 10MHZ
CALC:MARK:X:SLIM ON
THRESHOLD The THRESHOLD softkey defines a horizontal threshold line which represents the
lower limit of the peak search level range.

Remote command: CALC:THR -20dBm
CALC:THR ON
Deactivates peak search limits.
Activates and deactivates the markers symbol (x) that the R&S FSQ places on each
peak. The marker symbol is displayed only when the peak list is turned on.
Remote command: CALC:FUNC:FPE:ANN:MARK:STAT ON | OFF
Activates and deactivates the marker label that the R&S FSQ assigns to each peak.
The R&S FSQ ranks the markers according to their power level in descending order,
beginning with the strongest peak.
You can activate marker numbers only if the marker symbol is also active. If the
peak list is inactive, marker numbers cannot be displayed.
Remote command: CALC:MARK:FPE:ANN:LAB:STAT ON | OFF
Opens a input field to define the maximum number of peak list entries.
Remote command: CALC:MARK:FUNC:FPE:LIST:SIZE
The PEAK LIST EXPORT softkey stores the content of the marker peak list in ASCII
format to the specified file. The format of the decimal point is defined by the DECIM
SEP softkey.
Remote command: MMEM:STOR:PEAK 'C:\filename.txt'
DECIM SEP The DECIM SEP softkey selects the decimal separator between '.' (decimal point)
and ',' (comma) for the function PEAK LIST EXPORT.
With the selection of the decimal separator different language versions of evaluation
programs (e.g. Microsoft Excel) can be supported.
Remote command: FORM:DEXP:DSEP POIN
4.5.11.6 AF Demodulation
The R&S FSQ provides demodulators for AM and FM signals. With these demodulators,
a displayed signal can be identified acoustically through the use of the internal
loudspeaker or with headphones. The frequency at which the demodulation is
enabled is coupled to the markers. The sweep stops at the frequency determined by
the active marker for the selected time and the RF signal is demodulated. During a
measurement in the time domain (span = 0 Hz) the demodulation is continuously on.
