Remote command:
INST REC
In the receiver mode the R&S ESU measures the level at the set frequency with a
selected bandwidth and measurement time (see also
“RES BW” on page 4.21 and
“MEAS TIME” on page 4.31 ). Signal weighting is by means of detectors (see also
“DETECTOR” on page 4.29 ).
The functions for data reduction and the control of line impedance simulating net-
work are available in the
THRESHOLD SCAN and FINAL MEAS submenus.
A frequency scan can be performed after setting the start and stop frequency and
the step width. The scan subranges can be defined in a table (
DEFINE SCAN soft-
key).
The scan is started with the RUN SCAN softkey. In operating mode RECEIVER , the
RECEIVER hotkey and the MEAS hotkey directly open the RECEIVER menu. For a
detailed description refer to “Selection of the Measurement Function – MEAS Key”
on page 4.25 .
The R&S ESU is fitted with a preselection with switchable preselection. Preselection
is always switched on in receiver mode.
