Product Overview

The R&S ESPI7 Test Receiver implements many benefits of the Rohde & Schwarz full-compliance EMI test receivers for the precompliance class. When equipped with option R&S ESPI-K50, the ESPI7 can be used to measure the field-strength profiles of radio communications and broadcast networks.

Due to acommon platform system, the R&S ESPI7 offers 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 ESPI7 defines vital criteria such as functionality, measurement speed and accuracy for middle-end equipment and is 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.

Features and benefits of the Rohde & Schwarz ESPI7 Receiver include:

  • Frequency Range: 9 kHz - 7 GHz
  • EMI diagnostic measurements in development, production, quality assurance, service and maintenance
  • Pre- and post-certification testing in accordance with all civil EMI standards
  • Fast and easy interference testing in mobile use
  • Evaluation of field-strength coverage at very high measurement rates
  • Use as spectrum analyzer, including with selective input
  • Low measurement uncertainty (
  • Preselection filters and built-in 20 dB preamplifier (option)
  • Unprecedented measurement speed (measurement times from 100 µs)
  • Low noise level (NF = 12 dB with preamplifier)
  • Programmable scan tables with up to 10 subranges
  • Predefined limit lines and correction factors
  • Transducer factors and transducer sets
  • Autoranging and overload detection
  • Spectrum analyzer
  • Built-in AF demodulator and loudspeaker
  • USB interface, WinXP embedded
  • Bright 21 cm TFT color display
  • Battery or AC supply operation
