Rohde & Schwarz ESPI7 EMI Precompliance Receiver, 9 kHz - 7 GHz  

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
