R&S®ESPI Test Receiver

The reference instrument for the EMI precompliance class

Features

Due to their common platform system, both R&S ESPI models offer the additional benefits of the R&S FSP spectrum analyzers. These benefits far exceed the capabilities and functions of conventional precompliance test equipment. The R&S ESPI models define vital criteria such as functionality, measurement speed and accuracy for middle-end equipment and are especially designed to meet all demands of EMC testing during development. When the optional preselector/preamplifier is installed, the R&S ESPI models feature an excellent dynamic range and can perform precise EMI measurements in compliance with CISPR 16-1-1 for RFI signals with pulse repetition frequencies (PRF) from 10 Hz.

EMI test receiver

  • Optional built-in preselection and 20 dB preamplifier
  • Weighting with peak average, quasi-peak, RMS and CISPR average detectors (max. three detectors simultaneously)
  • CISPR-conforming EMI measurement bandwidths: 200 Hz, 9 kHz, 120 kHz, 1 MHz
  • Correct pulse weighting in line with CISPR 16-1-1 from 10 Hz pulse repetition frequency
  • Internal test routines for automated or interactive preview & final EMI measurements
  • Evaluation functions for prescan, data reduction (peak list) and final measurement
  • For all civil EMI standards such as CISPR, EN, ETS, FCC, ANSI C63.4, VCCI and VDE

Field-strength test receiver (option R&S ESPI-K50)

  • External trigger input
  • Additional channel filters with bandwidths of 5.6 MHz to 8 MHz for DVB-T, ISDB-T and ATSC signals
  • Very high sample rate (>100 ksamples/s on a discrete frequency)
  • Measurement on channel list (max. 1000 channels)
  • AM/FM modulation analysis (option R&S FSP-K7)

Spectrum analyzer

  • Resolution bandwidths from 10 Hz to 10 MHz (in steps of 1/3/10)
  • RMS detector for measurements on digitally modulated signals
  • Channel filter bandwidths from 100 Hz to 5 MHz as standard
  • Test routines for determining TOI, ACPR, OBW, amplitude statistics
