Cost-effective CISPR 14-1 Compliance Testing

12 April 2024 - The electromagnetic emissions of a wide range of household consumer devices that must comply with CISPR 14-1 require conducted tests up to 30 MHz. The R&S EPL1000 EMI test receiver of Rohde & Schwarz meets all requirements and complies with the CISPR test procedures for frequency bands A and B at an attractive price. The new R&S EPL1-K59 Click Rate Analyzer option provides click rate measurements in line with CISPR 14-1 and the Japanese DENAN Law requirements. These measurements are mandatory for household appliances and electric power tools with switching operations such as cookers, air conditioners and washing machines, because the switching process can cause discontinuous disturbance (“clicks”) or spikes in emissions.

The R&S EPL1000 supports both the conventional sequential frequency scan and the fast FFT-based time domain scan, enabling it to measure CISPR band A and B standard compliant in one shot. The latest edition 7 of CISPR 14-1 requires the click rate to be calculated separately for four frequencies in CISPR Band B. With the R&S EPL1-K59, the R&S EPL1000 can measure all four frequencies in parallel and evaluate the results four times faster than other EMI analyzers that measure each frequency sequentially.

The R&S EPL1000 is ideal for both PASS/FAIL compliance tests and troubleshooting during development. For development and debugging, hours of measured values can be evaluated in a few seconds. Users can save and recall settings and measurements for subsequent analysis. Data can also be exported for post-processing. Features such as zoom-in and markers help users to examine the values of individual clicks, and to easily measure time and level differences beyond standard click analysis.

The R&S EPL1000 is fully compliant with CISPR 16-1-1 (referenced by CISPR14-1) including the click rate analyzer measurement function. In addition to the standard calibration documents for the individual base units, documentation of the click rate verification using pulses defined in accordance with CISPR 16-1-1 is available, as required by EMC test houses.
