Feature Specification

RF attenuator switchable in 10-dB
Steps in the range 0 to 120 dB
One pre-selector with fixed tuning and five tracking pre-selectors, option ESVD-B2 with four additional filters with fixed tuning
Pre-amplifier with wide dynamic range, can be switched between pre-selector and 1^st 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 1^st 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 1/Q demodulator
Highly linear envelope detector with more than 70 dB dynamic range
Peak, overage 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

For field-strength measurements in the planning stage and operation of mobile radio networks (GSM, PCN)
