Cost-effective EMI test receivers offer expandable features
Rohde & Schwarz has introduced two highly flexible EMI test receivers at EMV2025, the EPL1001, which operates up to 1 GHz, and the EPL1007, which operates up to 7.125 GHz.
Offering engineers a flexible and cost-effective solution for EMI measurements, the EMI test receivers feature expandable capabilities to optimise and safeguard investments, as extra options can be integrated at any time as necessary. Depending on the configuration, these receivers can be used for measurements during the development phase, certification preparation, and final testing to ensure compliance with the latest EMI standards.
Engineers can start with a basic model that fits their current needs and budget. As requirements grow, the devices can be easily upgraded with advanced features. The basic versions of the test receivers include EMI bandwidth support for CISPR 16-1-1, DO-160 and MIL-STD-461 and detection to CISPR 16-1-1, RF input protection and automatic adaptable attenuation in 1 dB steps to easily handle strong signals. Optional preselection improves the measurement of broadband signals and short pulses. The preamplifier included in the preselection option enables the measurement of small signals. Adding option EPL1-B1611 results in full CISPR 16-1-1 compliant EMI test receivers, allowing the certification of the equipment under test.
The Time Domain Scan (TDS) enables the capture of entire CISPR bands A or B in a single shot and to measure above CISPR band B in 20 MHz increments, utilising CISPR band-associated resolution bandwidths. This approach saves valuable testing time and improves the detection of intermittent emissions. Detailed analysis is offered through spectrogram, zero span, and bar graph display functions. Additional upgrade options comprise real-time spectrogram, IF analysis, and 4-channel click rate analysis. Battery and DC power operations facilitate testing in diverse environments without being confined to a power outlet. The test receivers mitigate the need for extra equipment, as they provide functionalities beyond EMI measurements, such as an integrated spectrum analyser and an optional signal generator with tracking generator capability.
The EPL1001 and EPL1007 are intended for both EMC test engineers and R&D engineers. EMC test engineers require precise, rapid, and standard-compliant measurements to ensure that devices meet regulatory standards. R&D engineers seek detailed signal analyses for troubleshooting, continuous emission monitoring, and user-friendly interfaces during development.
