Rohde And Schwarz EPL1000 EMI Test Receiver with 5 kHz to 30 MHz Frequency Range and Color Display for CISPR16-1-1 Compliance Testing

The R&S®EPL1000 fully complies with CISPR16-1-1. The very fast time domain scan can check the complete CISPR bands A or B in a single shot. Built-in preselection ensures a high dynamic range and enables the acquisition of short pulses. The R&S®EPL1000 offers 4-channel click rate analysis, a real-time spectrogram function, IF analysis and further functions for detailed analysis. Automation simplifies measurements and ensures exact reproducibility of test sequences. These and many more functions make the R&S®EPL1000 ideal for conducted voltage and current measurements. Typical applications include precompliance measurements, precertification and certification in line with IEC, EN, CISPR and FCC.

• Preselection filters
• Time domain scan
• Tracking generator
• Battery operation
• Pulse protected input

• EMI detectors: peak, quasi-peak, CISPR-average, RMS-average (CISPR16-1-1)
• EMI bandwidth (6 dB):

  • 10 Hz, 100 Hz, 1 kHz, 10 kHz, 100 kHz and 1 MHz (MIL-STD-461 and DO-160)
• Preselection to increase dynamic range (filters for CISPR band A and B)
• Identify short pulses and small signals in the presence of strong signals
• Transducer factors to include used accessory characteristics
• Signal level adaptation to correctly measure strong or weak signals
• Limit line display and checking to easily evaluate measurement results
• Report generation to easily record, document and exchange results

The scan table enables the definition of multiple frequency ranges with individual measurement settings. This way, for example, the RBW can be defined individually for CISPR band A and B. Using the configured settings, the R&S®EPL1000 automatically measures all defined frequency ranges sequentially.

Line impedance stabilization networks (LISNs) from Rohde&Schwarz connected to the R&S®EPL1000 with an R&S®EZ-21 control cable can be remotely controlled by the R&S EPL1000, including selection of the line to be measured by the R&S®EPL1000. This function allows all lines connected to a LISN to be measured automatically.

The R&S®EPL1000 supports conventional level determination with only one frequency measured at a time (stepped scan). To reduce the total time, the measurement can be divided into preview and final measurement with peak search. With this method, final measurement is usually performed only for critical frequency points (peaks) using a detector required by the standard with a longer measurement time, allowing the total time to be considerably reduced.
