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.
