EMC certification system

29 October 2008 Test & Measurement

The new ESL EMI test receiver from Rohde & Schwarz is designed to meet the needs of cost-conscious users who want to perform precise pre-compliance and diagnostic measurements up to 3 GHz or 6 GHz. This compact instrument offers fully automated test sequences using the latest weighting detectors that conform to CISPR 16-1-1 specifications. The unit can also be used as a full-featured spectrum analyser.

The module measures a DUT's (device under test) electromagnetic disturbance in accordance with currently applicable commercial standards such as CISPR, EN and FCC. It uses standard-compliant bandwidths and a selection of disturbance weighting detectors such as quasi-peak, CISPR average and RMS average. The unit’s ease of use and fully automated test sequences facilitate EMC measurements. By performing a quick overview measurement, the ESL first determines the critical unwanted frequencies. Its detectors then perform a second targeted and careful measurement of only these frequencies in order to weight the disturbance.

The module stores the measurement settings and results on its hard disk.

Users can generate comprehensive reports by means of pre-compliance software. Since the unit is compact, lightweight and can be battery-operated, it is suitable for network operators and government agencies that need to measure field strength on site or to locate sources of disturbance.
