產品詳細介紹Product Introduction

The R&S®ESL is a compact, cost-effective measuring receiver. It includes all of the functions, bandwidths and weighting detectors that are needed to make EMC measurements in accordance with commercial standards. The receiver provides useful support to manufacturers of components, modules and devices who need to detect disturbances at the early stages of product development. They can thus take any required actions and avoid the expense of having to redevelop completed products. This also saves time and money during the certification process. The combination of very good RF characteristics and all of the important functions needed for fast, precise measurement and evaluation of the EMC of a device under test in accordance with commercial standards is unmatched in this class of instrument. The diverse analysis capabilities, high measurement speed and time-saving automated test routines make the R&S®ESL the obvious choice for any development lab that needs to prepare for EMC certification tests.

Features

Frequency range from 9 kHz to 3 GHz or 9 kHz to 6 GHz covering almost all commercial EMC standards
First-ever combination of an EMI test receiver and spectrum analyzer in the entry-level class
All major functions of an advanced EMI test receiver, including fully automated test sequences
Weighting detectors: max./min. peak, average, RMS, quasi-peak as well as average with meter time constant (CISPR-Average) and RMS-Average in line with the latest version of CISPR 16-1-1
Compact, lightweight instrument, can be battery-powered for mobile applications
