Rohde & Schwarz Unveils Versatile EMI Test Receivers at EMV2025, Enabling Smarter Investment Strategies

Caption: Flexible and cost-effective: The new test receivers are designed to meet a broad range of EMC measurement requirements.

The new R&S EPL1001 (up to 1 GHz) and R&S EPL1007 (up to 7.125 GHz) EMI test receivers provide engineers with a versatile and budget-friendly solution for electromagnetic interference testing. Designed with scalability in mind, they allow for future upgrades, ensuring long-term value and secure investment. Based on configuration, these receivers are suitable for use throughout various stages—from development and pre-certification to final compliance testing—meeting the latest EMI standards.

The newly launched EMI test receivers from Rohde & Schwarz are engineered to address a wide spectrum of EMC testing needs, emphasizing adaptability, cost-efficiency, and measurement accuracy. Engineers can begin with an entry-level model tailored to their current requirements and budget, with the option to upgrade later as testing demands evolve. Standard features include compliance with EMI bandwidths (CISPR 16-1-1, DO-160, and MIL-STD-461), EMI detectors, RF input protection, and automatic attenuation adjustment in 1 dB increments to handle high signal levels efficiently. An optional preselection module enhances broadband and pulse signal measurements, with an integrated preamplifier to detect smaller signals. With the EPL1-B1611 option, the receivers become fully compliant with CISPR 16-1-1, enabling equipment certification.

The Time Domain Scan (TDS) function allows for fast, comprehensive scanning of CISPR bands A or B in one pass and captures frequencies above band B in 20 MHz increments using appropriate resolution bandwidths—saving time and improving detection of sporadic emissions. Advanced analysis tools such as spectrograms, zero-span mode, and bar graph displays offer deeper signal insights.

Additional enhancements include real-time spectrograms, IF signal analysis, and 4-channel click rate monitoring. Support for battery and DC operation ensures flexibility in testing environments without the need for a fixed power source. Beyond EMI testing, these receivers also serve as integrated spectrum analyzers and can be expanded with signal and tracking generator capabilities, reducing the need for additional test equipment.

Targeted at both EMC and R&D engineers, the R&S EPL1001 and R&S EPL1007 provide fast, accurate, and standards-compliant testing for certification, along with in-depth analysis tools for troubleshooting and emissions monitoring during development—all in an intuitive user interface.

These new additions to the EPL series follow the R&S EPL1000 (launched in 2023) and will be available for order starting Q2 2025. They will be showcased at EMV 2025 in Stuttgart from March 25–27 at booth 615.
