R&S®ESPI Test Receiver
The reference instrument for the EMI precompliance class
Key Facts
The two models of the R&S ESPI test receiver implement many benefits of the Rohde & Schwarz full-compliance EMI test receivers for the precompliance class.
When equipped with option R&S ESPI-K50, the test receivers can be used to measure the field-strength profiles of radio communications and broadcast networks.
R&S ESPI — range of models
- R&S ESPI3: 9 kHz to 3 GHz
- R&S ESPI7: 9 kHz to 7 GHz
R&S ESPI — numerous applications
- 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
R&S ESPI — outstanding performance

- 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
EMI diagnostic measurements
Field strength measurements (PN scanner)
Result of measuring pulsed broadband interference with preselection (yellow) and without preselection (red). When preselection is disabled, the measurement result may be partly falsified by more than 10 dB due to compression and intermodulation.
