The test receiver ESVP measures and demodulates AM double-sideband,
single-sideband, pulse-modulated, and FM signals as well as narrowband and
broadband interference. High overload capacity, a wide dynamic range, and
manifold evaluation capabilities make the ESVP suitable for selective voltage
and twoport measurements - in automatic test systems, too - and all applications
in the field of radiomonitoring and EMC measurements.
Special features of the ESVP:
Synthesizer; frequency resolution 1 kHz, with SSB 100 Hz
High measurement accuracy (error <1 dB)
Wide dynamic range: noise figure typically 8 dB (preamplifier on),
third-order IP typically +20 dBm (preamplifier off)
Automatic gain correction in the whole frequency range after calibration
Measurement and display of voltage, field strength, current, spectral
density, and attenuation; conversion- and bandwidth- correction factors are
automatically taken into account
Additional evaluation capabilities for radiomonitoring:
modulation-depth and frequency-deviation measurements,
remote frequency and frequency-offset measurements thanks to internal IF
counter,
connection of radiomonitoring recorders (maximum of five ZSG 3),
SSB demodulator,
AF filter, squelch with programmable threshold, indication of date and time
of day
Storage of 10 complete device settings and of 5 data sets for automatic
frequency scanning
Special functions for frequency scanning with a set of up to 50 free
selectable fixed frequencies
Special functions for field-strength measurements in a moving vehicle.
