Test Receiver
20 MHz to 1.0 GHz
Option: B1- I/Q Demodulator

Preowned Instrument

-RF attenuator switchable in 10-dB steps in the range 0 to 120 dB
-One preselector with fixed tuning and five tracking preselectors, option ESVD-B2 with four additional filters with fixed tuning
-Preamplifier with wide dynamic range, can be switched between preselector and 1st mixer
-Crystal-stabilized synthesizer as 1st LO, variable in 100-Hz steps, sweep mode for fast frequency scans; frequency accuracy complying with GSM recommendations
-High-level mixer ensuring high isolation of 1st LO for converting the input frequency to the first IF (1354.7 MHz or 394.7 MHz)
-High-level mixers for conversion to the second (74.7 MHz) and third (10.7 MHz) IF
-IF filters (10 kHz, 120 kHz, 300 kHz and 1 MHz) in the third IF stage with group-delay optimization
-Precise I/Q demodulator
-Highly linear envelope detector with more than 70 dB dynamic range
-Peak, average and quasi-peak detectors operating in parallel, which enables simultaneous measurements in different weighting modes
-Peak indication with IF bandwidth correction factors for measuring broadband interference (PK/MHz) automatically taken into account
-Measurement monitoring by means of automatic overload detection in the relevant ESVD stages and by the permanently activated peak detector
-Logarithmic amplifier with more than 70 dB dynamic range
-12-bit A/D converter with short conversion time
-Measurement time selectable between 1 ms and 100 s
-Flash EPROMs allowing convenient and fast firmware updating with the aid of a PC
-Digital level indication on LC display and analog level indication on moving-coil meter taking into account transducer factors and their units
-Automatic calibration at a key-stroke with the aid of a high-precision built-in generator
-Demodulator circuits for FM, AM and A0; built-in loudspeaker and headphones connector
-Automatic monitoring of all synthesizer loops and supply voltages during operation
-Detection of faulty modules by built-in selftest facilities

The service-friendly modular design of ESVD ensures excellent results regarding RFI emission and immunity. A quiet, temperature-controlled blower minimizes self-heating of ESVD. Comprehensive built-in test functions allow any module requiring servicing to be easily identified and replaced independently of other modules.

The ESVD combines three instruments in one: 1)the system-compatible test receiver for GSM field-strength and EMI measurements; 2)the compact, manually tunable and battery-operated test receiver; 3)the automatic test receiver which performs EMI measurements and reports the results.
