Elite Invests in Nine R&S ESW Receivers

We’re proud to announce the recent acquisition of nine Rohde and Schwarz ESW EMI receivers for our Downers Grove laboratory operations. The units are presently being integrated into our EMC test stations and we’re quickly recognizing the significant benefit these state-of-the-art instruments will provide to our clients.

Elite’s ESW receivers will be supporting conducted and radiated emissions testing for our automotive, military and commercial aviation projects. OEMs such as BMW, Ford, and Fiat-Chrysler are encouraging the use of this time-saving technology to accelerate emissions testing. 

The ESW offers conventional stepped-frequency scans plus an ultrafast FFT-based time domain (TD) scan. The TD receiver significantly reduces the time required for standard-compliant certification tests and can also be operated with two CISPR detectors to carry out parallel measurements. 

It’s also a diagnostic and troubleshooting tool. For example, Elite clients can take advantage of real-time spectrum analysis. The spectrogram function displays the analyzed spectrum versus time, making rapidly changing interferers visible, and using frequency triggers information reveals critical and hidden signals. 

The ESW offers integrated notch filters, especially for the license-free ISM bands around 2.4 GHz and 5.8 GHz, which are used by wireless transmission technologies such as BluetoothTM and WLAN. Strong carrier signals in these bands can severely impact the dynamic range of instruments during EMI field strength measurements, and minor interference signals outside these bands can go undetected. With this instrument, we can perform more reliable and efficient certification measurements. 

The ESW incorporates a configurable auto-test feature, which makes it possible to automate complex measurement processes. This test configurator allows users to define parameters and criteria independently for preview measurements, peak search, and final measurements, using quasi-peak, CISPR-average, and RMS-average detectors. 

The test report generator helps operators document all parameters required for certification directly after measurements are taken.
