R&S ESU
This chapter provides a brief introduction to operating the R&S ESU EMI Test Receiver. A
more detailed discussion of the basic operating steps, e.g. selecting menus and setting
parameters, plus measurement examples are provided in the Operating Manual, chapters 2
and 4.

5.1 Introduction

This section describes a typical and simple measurement task for an EMI test receiver. Each
operating step is explained with the aid of R&S ESU for rapid familiarization of the user without
the need to know all the details of the operating functions.
In the introductory example a standard measurement of level and frequency is performed with
the aid of the SCAN TABLE. This measurement is an overview and pre-certification
measurement to be performed before the final standard-conformal measurement is carried
out. Each operating step is explained with the aid of R&S ESU for rapid familiarization of the
user without the need to know all the details of the operating functions.
In the following example, the R&S ESU is set to default values in the receiver mode. The
default setup is activated by pressing first the RECEIVER hotkey and then the PRESET key.
The main default parameters in receiver mode are listed in the following table:
Parameter
Receiver frequency
RF attenuation
Preamplifier
Quick Start Guide 1302.6163.62 - 04
If unknown (RFI) signals are to be measured, it is strongly
recommended to provide for at least 10 dB RF attenuation at the RF
input in order to protect the input circuit.
