R&S®ESCI EMI Test Receiver
For compliance tests meeting all civil standards from 9 kHz to 3 GHz
The R&S ESCI sets new standards in scope of functions, measurement speed and measurement accuracy up to 3 GHz.
The use of innovative techniques such as an LSI frontend and largely digital signal processing, in conjunction with ASICs developed by Rohde & Schwarz, yields excellent specifications and high reliability.
The functionality of a conventional "compliance tester" for civil applications has been expanded by a wide range of spectrum analyzer functions.
EMI test receiver
- Integrated preselection and 20 dB preamplifier
- Weighting with peak, average, quasi-peak, RMS, CISPR-AV and CISPR-RMS decetors (max. three detectors simultaneously)
- CISPR-conforming EMI measurement bandwidths: 200 Hz, 9 kHz, 120 kHz, 1 MHz
- Pulse weighting conforming to CISPR 16-1-1, including single pulses
- For all civil EMI standards such as CISPR, EN, ETS, FCC, ANSI C63.4, VCCI and VDE
Spectrum analyzer
- Resolution bandwidths from 10 Hz to 3 MHz (in steps of 1/3/10)
- RMS detector for measurements on digitally modulated signals
- Channel filter bandwidths from 100 Hz to 5 MHz
- Test routines for determining TOI, ACPR, OBW, amplitude statistics
Further EMC performance features
- Total measurement uncertainty < 1 dB (receiver mode)
- Noise figure typ. 7 dB
- Fast overview measurements in spectrum analyzer mode
- User-programmable scan tables
- Combination of prescan and spectrum analysis (split-screen/mixed mode)
- Display and comparison of results with limit lines
- Inclusion of correction values for cable loss, coupling networks and antennas in the form of transducer factors and transducer sets
- Data reduction and modification of frequency list for weighted final measurement
- Bargraph display for various detectors with Max Hold indication
- Autoranging and overload detection
- Built-in AF demodulator with loudspeaker
- Bright 21 cm TFT color display
Split screen display with prescan results (two traces), final results (peak list) and bargraphs (three parallel detectors)
Display of a modulated or drifting signal, mapped to the center frequency
MIXED mode bargraph and spectrum measurement: simultaneous display of standard-conforming bargraph measurement and fast sweep
Display of a prescan results (pk and avg) including the selected phase and grounding condition (EMI conducted)
Setting of parameter coupling between analyzer and receiver mode
