Rohde & Schwarz EMI test receiver

Rohde & Schwarz has extended its R&S ESR family with the release of an EMI test receiver that covers the frequency range from 10Hz to 26.5GHz. The R&S ESR26 performs conducted or radiated certification measurements in line with commercial standards such as EN, CISPR and FCC as well as military standards. The North American FCC standard and the CISPR standard both specify EMI measurements up to 18GHz.

As a result of its broadband architecture, the R&S ESR26 performs standard-compliant disturbance measurements up to 6000 times faster than other testers, stated the firm. EMI measurements that took hours in the past can now be completed in just seconds, saving users valuable time on the way to obtaining desired results, added Rohde & Schwarz.

In addition, the instrument offers comprehensive diagnostic tools to support design engineers. The persistence mode allows users to clearly differentiate between pulse and continuous disturbances. It displays the probability of amplitudes occurring at specific frequencies using different colours, making it possible to detect disturbances that are hidden by broadband signals. The frequency mask trigger responds to specific events within a disturbance spectrum. If the mask is violated, a trigger is activated. The measurement is stopped, and the user can analyse the disturbance and its effect.

Users can verify existing results by means of the conventional stepped frequency scan of the R&S ESR26. Plus, the instrument is a full-featured spectrum analyser, providing tried and tested analysis tools such as IF analysis and time domain display.

Besides the test receiver's compact, robust design and its low weight, a number of options make the R&S ESR26 ideal for field use. These include a DC power supply with rechargeable battery pack, a solid state drive (SSD) and an optional ruggedized housing, the company detailed.

The R&S ESR26 not only features outstanding functionality, it also scores top marks for ease of operation and its clearly structured touchscreen. Complex measurements and automated test sequences are easy to configure. The R&S EMC32 software can be used to remotely control the R&S ESR26 and integrate it into complex EMC test systems for automated measurement sequences.

The R&S ESR26 is available from Rohde & Schwarz.
