1121 Audio Analyzer - BOONTON - #1

AUDIO TEST INSTRUMENTS

The Model 1121 Audio Analyzer is an enhanced version of our very successful Model 1120. The Model 1121 incorporates: selectable output impedances of 50, 150 and 600 ohms; 16 volt rms output; additional 0.3 millivolt full scale measurement range, and quasi-peak detection. The 1121 can be used as a direct re­placement in present 1120 applications. The instrument auto­matically tunes and autoranges for maximum accuracy and resolu­tion. Distortion, frequency response, AC and DC voltage meas­urements are a single keystroke away. With a built in low distortion audio source, the instrument is ideally suited to stimulus response applications. Microprocessor control of source and analyzer allows the instrument to perform swept measurements.

For accurate measurement of complex waveforms and noise, the audio analyzer uses true rms average or quasi-peak de­tection. Accurate distortion measurements can typically be made down to better than -90 dB (0.003%) between 20 Hz and 20 kHz. Over the same frequency range, flatness measurements are possible to 0.05 dB (0.5%). The audio analyzer precision recipro­cal counter gives fast, accurate characterization of audio fre­quencies.
