6 Receiver Mode
Equipped with firmware option R&S FSH-K43 (order no. 1304.5635.02), you can
perform receiver and channel measurements (or scans) with your R&S FSH.
In receiver mode, the R&S FSH measures the power level of a particular frequency or
a customized set of frequencies instead of sweeping over (parts of) the frequency
spectrum. The R&S FSH shows the scan results in result displays that have been
designed for just such measurement tasks.
The receiver mode also adds the necessary functions like bandwidths or detectors to
perform measurements according to CISPR.
By default, the R&S FSH is in the operating mode you have been in last after you have
turned it on. To switch to the receiver mode from another operating mode, proceed as
follows.
M
Press the MODE key.
M
Press the "Receiver Mode" softkey.
The R&S FSH starts the receiver mode in single frequency measurement mode.
6.1 Selecting the Measurement Mode
In receiver mode, the R&S FSH features two measurement modes.
C
Fixed Frequency / Channel
C
Frequency Scan / Channel Scan
Fixed measurement mode is designed for measurements on single frequencies. Scan
measurement mode performs scans on a defined set of frequencies.
6.1.1 Performing Single Frequency Measurements
The R&S FSH shows the result of the single frequency measurement in a result
display that contains three main elements.
C
Measurement (or receive) frequency
C
Power level measured at the receive frequency
C
Horizontal bargraph that graphically represents the currently measured power
level.
In the default state, the R&S FSH performs the measurement on a single receive
frequency. If it instead shows the result display for a frequency scan, you can access
the single frequency result display manually.
M
Press the MEAS key.
M
Press the "Fixed Freq" softkey.
The R&S FSH shows the result display for single frequency measurements.
