6 Spectrum Measurements
You can also perform conventional spectrum analysis with the R&S ESR.
When you start the R&S ESR for the first time or after a preset, it starts in receiver
mode. If it is inactive, press the [MODE] key and select the "Spectrum" softkey in the
corresponding menu to enter the spectrum mode.
This chapter of the manual describes all functionality that is available in spectrum
mode.

Chapter 6.1, "Measurements", on page 221
This section describes how to configure and perform specific measurements that
are available in Spectrum mode.
Measurement examples are provided in the Quick Start Guide, chapter 5 "Basic
Measurement Examples" and the Operating Manual, chapter "Advanced Measure-
ment Examples".

Chapter 6.3, "Analysis", on page 387
This section decribes the tools that are available to analyze measurement results.

Chapter 6.2, "Configuration", on page 342
This section describes general measurement parameters. The general measure-
ment parameters apply to all measurements performed in Spectrum mode.
6.1 Measurements
In the Spectrum mode, the R&S ESR provides a variety of different measurement func-
tions.
The individual functions are described in detail in the following sections.
6.1.1 Power Measurements – MEAS Key
With its power measurement functions, the R&S ESR is able to measure all the neces-
sary parameters with high accuracy in a wide dynamic range.
A modulated carrier is almost always used (except e.g. SSB-AM) for high-frequency
transmission of information. Due to the information modulated upon the carrier, the lat-
ter covers a spectrum which is defined by the modulation, the transmission data rate
and the signal filtering. Within a transmission band each carrier is assigned a channel
taking into account these parameters. In order to ensure error-free transmission, each
transmitter must be conforming to the specified parameters. These include among oth-
ers:
●
the output power
●
the occupied bandwidth, i.e. the bandwidth which must contain a defined percent-
age of the power
●
the power dissipation allowed in the adjacent channels
