R&S ESU
Fig. 4.32 Normalized measurement, shifted with REF VALUE POSITION 50%
Remote command:
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 ESU 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 forma-
tion can also be shifted down by 10 dB so that it will again coincide with the trace
(see
4.338
Fig. 4.33).
