R&S ESR

5 Receiver Mode

In receiver mode, the R&S ESR measures the level at the set frequency with a
selected bandwidth and measurement time. Signal weighting is by means of detectors.
A frequency scan can be performed after setting the start and stop frequency and the
step width. Scan subranges are defined in a table.
Functions for data reduction and the control of line impedance simulating network are
available.
Preselection is always switched on in receiver mode.

5.1 Measurements and Result Displays

The R&S ESR provides several types of measurements.
●
The bargraph result display shows the signal level on a single frequency.
●
Fast prescans together with several data reduction methods are used to reduce the
amount of data in the final measurements. The final measurement is then per-
formed only on frequencies that have a high interferer level.
●
The final measurement may be either automatic or in interactive mode. Automatic
control functions for line impedance stabilization networks (LISN) are available.
●
Time domain scans (option R&S ESR-K53) reduce the required overall measure-
ment times enormously by using fast fourier transform (FFT) of frequency sections.
Time domain scan may even eliminate the need for preliminary measurements.
●
Fixed frequency mode for click analysis and IF spectrum analysis mode for manual
tuning are available.
●
The spectrogramm result display provides an additional data evaluation method by
showing the signals over time.

5.1.1 Bargraph Measurement

The bargraph result display shows the signal level on a single frequency. It is a basic
result display that indicates the signal level numerically and graphically.
The length of the bar represents the signal level at the current receiver frequency eval-
uated with the currently selected detector.
