Original Manufacturer Description:
The 1121 incorporates selectable output impedance of 50, 150 and 600 ohms, 16 volt RMS output, additional 0.3 mV full scale measurement range, and quasi-peak detection. The 1121 Audio Analyzer also tunes and manages auto-ranging automatically for maximum accuracy and resolution. Distortion, frequency response, AC and DC voltage measurements require only one single keystroke. The instrument is ideally suited for stimulus response applications because of an on-board low distortion audio source. Internal control of the source and analyzer allows for swept measurements.
For the accurate measurement of complex waveforms and noise, the audio analyzer uses true RMS average or quasi-peak detection. Accurate distortion measurements can be made to -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 and accurate characterization of audio frequencies.
