Input 50 Ω/75 Ω
Uses 50 Ω or 75 Ω as reference impedance for the measured levels. Default setting is
50 Ω.
The setting 75 Ω should be selected if the 50 Ω input impedance is transformed to a
higher impedance using a 75 Ω adapter of the RAZ type (= 25 Ω in series to the input
impedance of the instrument). The correction value in this case is 1.76 dB = 10 log (75
Ω/50 Ω).
All levels specified in this Operating Manual refer to the default setting of the instru-
ment (50 Ω).

Res BW Manual
Opens an input field to define the measurement or resolution bandwidth.
The R&S ESRP supports a selected set of resolution bandwidths. If you enter a num-
ber that is not supported, the R&S ESRP rounds the value up to next available band-
width.
You can also select some bandwidths directly with the corresponding softkeys in the
"Bandwidth" menu.
For more information see Chapter 5.2.1, "Measurement Bandwidth" , on page 142.
Remote command:
[SENSe:]BANDwidth|BWIDth[:RESolution]
on page 639
CISPR RBW Uncoupled
Cancels the coupling of the IF bandwidth to the frequency range with the activated
quasipeak detector, CISPR Average or RMS average detector.
See also Chapter 5.2.2, "Detectors" , on page 143.
Remote command:
[SENSe:]BANDwidth|BWIDth[:RESolution]:AUTO

Filter Type
Selects the filter type.
The available resolution bandwidths depend on the filter selection.
The R&S ESRP provides the following filter types:
