Advantest TR4135 Spectrum Analyzer
The Advantest TR4135 Spectrum Analyzer uses
a synthesized local oscillator to enable high stability spectrum analysis.
It features frequency coverage from 10 kHz to 3.6 GHz, input range of -131
to +20 dBm, a maximum resolution of 30 Hz, residual FM of 30 Hzp-p and
skirt noise characteristics of -105 dBc/Hz at 20 kHz from the carrier. The
Advantest TR4135 is suitable for measurements on 900-MHz mobile
radiotelephone equipment, fixed broadcast stations and mobile A-band
equipment. It can be used for satellite broadcast received field strength
measurements and in the evaluation and testing of CATV equipment. It
enables high-precision frequency measurements and directly readable field
strength measurements by means of antenna calibration and is further
capable of quasipeak-value measurements conforming to CISPR standards.
