Featuring built-in preselection, ESPC is able to perform accurate interference measurements with pulse repetition frequencies (PRF) to as low as 10 Hz in line with CISPR 16-1. An overload detection system for the complete receiver signal path from the input through to the IF stages warns the user in case of erroneous measurements.
Preselection and overload protection ensure reliable and reproducible measurements which is a particularly important aspect in automatic test runs. Incorrect EMI diagnostics at an early production stage cause high costs, delay the product launch and hence put at risk the return on high investment. If a product does not pass the compliance test for whatever reason, it is all the more important that the test receiver used for post-qualification is absolutely reliable so that rework can be performed within the shortest possible time and the compliance test repeated as soon as possible.
