There are two models of R&S ESPI test receivers at the pre-compliance level, integrating all the advantages of Rohde & Schwarz's certified EMI test receivers. If the optional R&S ESPI-K50 is selected, the test receiver can be used to measure the field strength coverage of communication and broadcast networks.

R&S ESPI — Models
R&S ESPI3: 9 kHz to 3 GHz
R&S ESPI7: 9 kHz to 7 GHz

R&S ESPI — Multiple Applications
EMI diagnostic measurements during R&D, production, quality assurance, repair, and maintenance
Pre-compliance and post-compliance testing in accordance with all civil EMI standards
Fast and simple interference testing in mobile applications
Field strength coverage evaluation with extremely fast measurement speed
Use as a spectrum analyzer, including selective input
R&S ESPI — Outstanding Performance
Low measurement uncertainty (receiver mode <1.5dB)
Preselector filter and internal 20dB preamplifier (optional)
High measurement speed (measurement time starting from 100 μs)
Low noise level (with preamplifier NF=12dB)
Programmable scan table, up to 10 sub-frequency ranges
Predefined limit lines and correction factors
Correction factors and combinations of correction factors
Automatic range adjustment and overload detection

Spectrum Analyzer
Built-in audio demodulation and speaker
USB interface
21cm TFT color LCD display
Battery or AC power operation

Thanks to the use of a universal platform system, both models of the R&S ESPI offer all the functions of the R&S FSP spectrum analyzer. These capabilities make them far exceed traditional pre-compliance test equipment in terms of performance and functionality. The R&S ESPI sets important standards for mid-range instruments, such as functionality, measurement speed, accuracy, and especially the ability to meet all EMC testing requirements during the R&D process.

When the optional preselector/preamplifier is installed, the R&S ESPI has a very large dynamic range, enabling precise EMI measurements in compliance with CISPR 16-1-1 for RF interference signals with pulse repetition frequencies above 10 Hz.
