R&S Rohde And Schwarz EPL1000 EMI Test Receiver For Compliance Testing

Description of R&S Rohde And Schwarz EPL1000

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.

Features & benefits for EPL1000

Automatic measurement of multiple frequency segments with individual settings

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.

Automatic measurement of multiple lines connected to a LISN

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. On the R&S®EPL1000 GUI, the user simply selects the lines to be measured automatically

Preview and final measurement

The R&S®EPL1000 also 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. Preview measurement, peak search and final measurement with evaluation can be completely automated in the R&S®EPL1000.
