Rohde & Schwarz ESPI3 Test Receiver

The Rohde & Schwarz ESPI3 is a test receiver designed for pre-compliance electromagnetic compatibility (EMC) testing in the frequency range from 9 kHz to 3 GHz. It combines the functions of a test receiver and a spectrum analyzer, providing high accuracy and measurement speed.

Main Specifications:

• Frequency Range: 9 kHz – 3 GHz
• Bandwidth: EMI bands of 200 Hz, 9 kHz, 120 kHz, 1 MHz; resolution bandwidths from 10 Hz to 10 MHz
• Detectors: Peak, Quasi-Peak, RMS, Average; supports simultaneous use of up to three detectors
• Measurement Accuracy: in spectrum analyzer mode — 0.5 dB; in receiver mode — less than 1.5 dB
• Displayed Average Noise Level (DANL): –155 dBm (1 Hz) for frequencies below 1 GHz
• Phase Noise: –113 dBc/Hz at 10 kHz offset and 500 MHz frequency
• Interfaces: GPIB, Centronics, RS-232-C; optional LAN

Features:

• High Measurement Speed: measurement times from 100 µs to 100 s in receiver mode
• User-defined Scan Tables: supports up to 10 subranges with different parameters
• Optional Pre-amplifier and Pre-selector (ESPI-B2): enhances dynamic range and overload protection
• Large 21 cm Color TFT Display: convenient display of results and measurement parameters

Applications:

The ESPI3 supports all major commercial EMI standards, including CISPR, EN, ETS, FCC, ANSI C63.4, VCCI, and VDE, making it an ideal tool for developers and engineers involved in pre-compliance EMC testing and diagnostics.
