R&S FSQ Signal Analyzer - Rohde & Schwarz

R&S FSQ Instrument Functions
External Generator Control – Option R&S FSP-B10
Fig. 4.31 Normalized measurement, shifted with REF VALUE POSITION 50%
Remote command: DISP:WIND:TRAC:Y:RPOS 10PCT
REF VALUE The REF VALUE softkey activates the input of a level difference which is assigned
to the reference line.
In the default setting, the reference line corresponds to a level difference of 0 dB. If
e.g. a 10-dB attenuator pad is inserted between DUT and R&S FSQ input between
recording of the calibration data and normalization, the trace will be shifted down by
10 dB. By entering a REF VALUE of –10 dB the reference line for difference formation
can also be shifted down by 10 dB so that it will again coincide with the trace
(see Fig. 4.32).
