Informação

Correct interference weighting to CISPR 16-1 down to 10-Hz pulse repetition frequency Integrated preselection For all commercial EMI standards such as CISPR, EN, ETS, FCC and ANSI C 63.4, VCCI as well as VDE Automatic overload detection Power sourcing from internal or external battery Easy to use thanks to built-in macro functions EMI Software under Windows supplied as standard EMI Precertification Test Receiver ESPC has been derived from various Rohde & Schwarz full-compliance re­ceiver models and thus opens up ver­satile applications in the field of EMI precompliance. It is a budget-priced solution for emission tests at all stages of development and production of electrical products. With a view to ob­taining the CE conformity mark, this test receiver will be used wherever EMI tests become necessary prior to acceptance testing in order to mini­mize the risks involved and the time taken for full-compliance tests. 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. Special features of ESPC Large frequency range from 150 kHz to 1000 M H z Options for frequency extension to 9 kHz and 2500 M H z Parallel detectors for average, peak and quasi-peak reading Fast synthesizer: frequency resolu­tion 10 and 100 Hz
