Compact test receiver with spectrum analyser provides flexible test capability in EMC laboratories

New EMI test receiver launches with spectrum analyser and signal generator for emission measurements up to 30 MHz

The R&S EPL1000 is a compact, complete and CISPR 16-1-1 compliant test receiver for quick and precise EMI measurements up to 30 MHz. The additional spectrum analyzer and signal and tracking generator make the R&S EPL1000 ideal for various lab applications and is of particular use for pre-compliance testing purposes. The new EMI test receiver made its first appearance to the EMC testing industry at the EMV 2023 event in Stuttgart in March this year.

The event saw instrumentation specialist, Rohde & Schwarz demonstrate the receiver as an instrument capable of reliable certification measurements with minimum test times. Being compliant to CISPR 16-1-1, the R&S EPL 1000 is suitable for being used for measurements that meet the standard’s certification requirements and so companies preparing for compliance tests at test houses are able to perform verification checks beforehand.

In this respect, the instrument is able to reduce the level of uncertainty in pre-compliance measurement tasks. The very fast time domain scan lets the R&S EPL1000 check all frequencies in CISPR bands A or B in a single shot for quick and seamless measurements over extended periods of time whenever desired or necessary. A user friendly GUI helps EMC engineers quickly find infrequent emissions and gain a good overview. Reproducible and standard compliant test results ensure the product under test meets its quality requirements.

The R&S EPL1000 has a pulse protected input – An autoranging function prevents the overloading of the signal processing chain to ensure correct measurement results. Built-in preselection ensures a high dynamic range and enables the acquisition of short pulses. For detailed signal analysis, the R&S EPL1000 has spectrogram and IF analysis functions.

Automation simplifies measurements and ensures exact reproducibility of test sequences. For example, all lines connected to a Rohde & Schwarz LISN can be checked for CISPR bands A and B at the push of a button. Results are automatically compared with configured limit values and the R&S EPL1000 displays the result for the entire measurement as PASS/FAIL. The integrated report generator allows the result and measurement details to be easily saved and printed.

The additional spectrum analyser functions help with a detailed EMI analysis. An optional integrated continuous wave signal generator with a tracking generator function characterises any accessories that are used along with cables without the need to use an external signal generator. In addition to the standard mains supply, the compact test receiver can be run on 12/24 V DC or battery, making it very flexible and portable.

The R&S EPL1000 is ideal for conducted voltage and current emission measurements. The frequency range to 30 MHz is ideal for testing commercial products against ISO, EN, CISPR and FCC standards. Apart from the pre-compliance usage capability, the R&S EPL1000 supports product certification, measurements during product development phases and market surveillance.

The R&S EPL1000 can be used with the R&S ELEKTRA test software. R&S ELEKTRA helps minimise test times and simplifies configuring test systems and running test procedures in line with the EMC standards. The instrument speeds up test execution and provides comprehensive and customizable test reports.
