Range Start = Start frequency of the scan range. To avoid overlapping scan ranges, the stop frequency of
the previous scan range is adjusted if necessary.
Range Stop = Stop frequency of the scan range. To avoid overlapping scan ranges, the start range of the
next scan range is adjusted if necessary.
Stepsize
= Frequency stepsize within the scan range. If you define a stepsize that is larger than the
range itself, the R&S
ESRP only measures the start and stop frequencies of the scan range.
The step size is available if the
is either linear or logarithmic. If the step mode is
linear, the step size is a value in Hz. If the step mode is logarithmic, the step size is a per-
centage.
Res BW
= Measurement bandwidth used within the scan range, see
ESRP displays an exclamation mark if the selected
measurement bandwidth is not compatible to the bandwidth required by CISPR for the corre-
sponding frequency range.
Meas Time
= Measurement time applied to the scan range, also see
Auto Rang-
ing
= Turns automatic selection of the input attenuation on and off, see
RF Attenua-
tion
= Attenuation level at the RF input.
Preamplifier = Turns the preamplifier on and off. If you select "Auto", the preamplifier is also considered in
the auto ranging process.
RF Input
= Selects the RF input.

Peak List and Data Reduction
Peak List
The Peak Search function of the R&S
ESRP can be used to create a peak list contain-
ing only the measurement values of high interferers. In a fast prescan the signal is
measured against a limit line, and the level values above the set margin are written into
the peak list. The resulting peak list then is used for the final measurement where only
the frequencies in the peak list are measured with the required detector.
