Cost effective EMI test receivers with expandable features

Rohde & Schwarz unveiled two versatile EMI test receivers, the EPL1001 and the EPL1007, at EMV2025. The EPL1001 operates up to 1 GHz, while the EPL1007 extends the range up to 7.125 GHz. These test receivers offer engineers a flexible and cost-effective solution for EMI measurements, with expandable capabilities that allow for optimization and protection of investments. Additional options can be seamlessly integrated as needed, making them suitable for various stages of product development and certification preparation to ensure compliance with the latest EMI standards.

Engineers can begin with a basic model that aligns with their current requirements and budget. As needs evolve, the devices can be easily upgraded with advanced features. The base versions of the test receivers support EMI bandwidth for CISPR 16-1-1, DO-160, and MIL-STD-461, along with detection to CISPR 16-1-1, RF input protection, and automatic adaptable attenuation in 1 dB increments to handle strong signals effortlessly. Optional preselection enhances the measurement of broadband signals and short pulses, with the preamplifier in the preselection option enabling the detection of small signals. By adding option EPL1-B1611, users can achieve full CISPR 16-1-1 compliance, facilitating equipment certification.

The Time Domain Scan (TDS) feature allows for the capture of entire CISPR bands A or B in a single shot and measurement above CISPR band B in 20 MHz steps, utilizing resolution bandwidths associated with CISPR bands. This approach saves time during testing and enhances the detection of intermittent emissions. Detailed analysis is provided through spectrogram, zero span, and bar graph display functions. Additional upgrade options include real-time spectrogram, IF analysis, and 4-channel click rate analysis. Battery and DC power operations enable testing in diverse environments without the need for a power outlet. The test receivers offer functionalities beyond EMI measurements, such as an integrated spectrum analyzer and an optional signal generator with tracking generator capability.

The EPL1001 and EPL1007 cater to both EMC test engineers and R&D engineers. EMC test engineers rely on precise, rapid, and standard-compliant measurements to ensure devices meet regulatory standards. On the other hand, R&D engineers benefit from detailed signal analyses for troubleshooting, continuous emission monitoring, and user-friendly interfaces during the development process.

Overall, the introduction of the EPL1001 and EPL1007 EMI test receivers by Rohde & Schwarz marks a significant advancement in EMI measurement technology. With their flexible and expandable capabilities, these devices provide engineers with a versatile solution for EMI testing throughout the product development lifecycle. By offering a range of features and upgrade options, these test receivers empower users to adapt to evolving requirements and ensure compliance with the latest EMI standards, making them essential tools for EMC test engineers and R&D engineers alike.
