R&S FSL Tracking Generator (Models 13, 16 and 28)

Ref Value Position
Switches the reference line on or off. The reference line marks the reference position at which
the normalization result (calculated difference with a reference trace) is displayed. For details on
the reference line see "Calibration mechanism" on page 4.136.
Remote: DISP:WIND:TRAC:Y:RPOS 10PCT
Ref Value
Opens an edit dialog box to enter a position value that shifts the reference line vertically. By
default the reference line corresponds to a difference of 0 dB between the currently measured
trace and the reference trace.
If, e.g. after a source calibration, a 10 dB attenuation is inserted into the signal path between
DUT and R&S FSL input, the measurement trace will be moved by 10 dB down. Entering a
reference value of –10 dB will shift the reference line also by 10 dB down 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: DISP:WIND:TRAC:Y:RVAL –10dB
Recall
Restores the settings that were used during source calibration. This can be useful if device
settings were changed after calibration (e.g. center frequency, frequency deviation, reference
level, etc).
