Advantest TR9404 Digital Spectrum Analyzer
TR9404 Digital Spectrum Analyzer is a sophisticated instrument cobining high-speed, high-sensitivity analog design with precision digital computing and signal processing tecnologies.
The TR9404 incorporates all analyzing functions needed for a dual channel FFT spectrum analyzer: i.e. transfer frunction, coherence function, correlation function and impulse response analysis, spectrum zooming, and so forth.
The wide-band, high-sensitivity specifiactions include a mesurable frequency range of 0.0025 to 100 kHz, input level range of +30 to -120 dBV (31.6V to 1 microV rms), and dynamic range of more than 72 dB. The TR9404 may be used to measure input-output and statistical relationships associated with the analysis of vibration, noise, structures and audio equipment, as well as chemical analysis, somatological researches, communication line instrumentation, semiconductor...
