4 Measurement Modes

The R&S ESR provides several measurement modes for different analysis tasks.

When you activate a measurement mode, a new measurement channel is created. The

channel determines the settings for that measurement mode. Each channel is dis-

played in a separate tab on the screen.

SCPI command:

INSTrument[:SELect] on page 636

To change the measurement mode

1. Press the MODE key.

A menu with the currently available measurement modes is displayed.

2. To activate a different mode, press the corresponding softkey.

4.1 Receiver Mode

In Receiver mode, the R&S ESR measures the signal level at a particular frequency. It

also provides tools (e.g. detectors or bandwidths) necessary to measure the signal

according to EMC standards. The Receiver mode is the default mode of the R&S ESR.

The R&S ESR also provides function for IF analysis if you have equipped your

R&S ESR with firmware application R&S ESR-K56. IF analysis is not a separate mea-

surement mode but is integrated into the Receiver mode.

For more information on functionality available for the Receiver mode see Chapter 5,

"Receiver Mode", on page 142.

SCPI command:

INST REC

4.2 Spectrum Mode

In Spectrum mode the provided functions correspond to those of a conventional spec-

trum analyzer. The analyzer measures the frequency spectrum of the RF input signal

over the selected frequency range with the selected resolution and sweep time, or, for

a fixed frequency, displays the waveform of the video signal.

The Spectrum mode also provides spectrogram measurements. The spectrogram is

not a separate measurement mode, but rather a trace evaluation mode. Note also that

the Spectrogram available in Spectrum mode is independent of that available in real

time mode. It provides similar functionality but uses different data acquisition methods.

For more information on functionality available for the Spectrum mode see Chapter 6,

"Spectrum Measurements", on page 221.
