Reference Value Position ← Source Cal
Switches the reference line on or off. The reference line marks the reference position
at which the normalization result (calculated difference to a reference trace) is dis-
played. For details on the reference line see Chapter 3.6.4.5, "Normalization",
on page 492.
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:RPOSition on page 751
Reference Value ← Source Cal
Opens an edit dialog box to enter a position value that shifts the reference line verti-
cally. By default, the reference line corresponds to a difference of 0 dB between the
currently measured trace and the reference trace.
If a 10 dB attenuation is inserted into the signal path between DUT and
R&S FSVA/FSV input, for example after a source calibration, the measurement trace is
moved down by 10 dB. Entering a reference value of -10 dB will also shift the refer-
ence line down by 10 dB and place the measurement trace on the reference line. The
deviation from the nominal power level can be displayed with higher resolution (e.g. 1
dB/div). The power is still displayed in absolute values.
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:RVALue on page 752
Recall ← Source Cal
Restores the settings that were used during source calibration. This can be useful if
instrument settings were changed after calibration (e.g. center frequency, frequency
deviation, reference level, etc).
Remote command:
[SENSe:]CORRection:RECall on page 791
Save As Trd Factor ← Source Cal
Uses the normalized measurement data to generate a transducer factor with up to 625
points. The trace data is converted to a transducer with unit dB and stored in a file with
the specified name and the suffix.trd under "c:\r_s\instr\trd". The frequency
points are allocated in equidistant steps between start and stop frequency. The gener-
ated transducer factor can be further adapted using the "Transducer" softkey in the
"SETUP" menu.
The "Save As Trd Factor" softkey is only available if normalization is switched on.
Remote command:
[SENSe:]CORRection:TRANsducer:GENerator on page 792
Modulation
Opens a submenu to define modulation settings. This submenu contains the following
commands:
●
"External AM" on page 478
●
"External FM" on page 478
●
"External I/Q" on page 478
●
"Modulation OFF" on page 478
