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
