The 1121A audio analyzer is a test instrument designed for accurate measurements of AC and DC voltage, distortion, SINAD, signal-to-noise ratio, and frequency, with an integrated low-distortion audio source. It features selectable output impedances of 50, 150, and 600 ohms, a 16 Vrms output level, and a 0.3 mV full-scale measurement range. The unit uses quasi-peak and true RMS detection, with frequency measurement via a 10 MHz TCXO timebase. Input impedance is 100 kΩ ±1% with <300 pF capacitance per side. It measures distortion down to 0.00001% and supports bandwidths up to 500 kHz. Dimensions are 45.1 cm wide, 14.9 cm high, and 45.8 cm deep, weighing 11.3 kg. It operates from 100 to 240 VAC, 50 to 400 Hz, and requires indoor use within 0°C to 55°C. Rear panel connectors include IEEE-488, monitor, SYNC, X CLK, X AXIS, Y AXIS, PENUP, and TTL inputs/outputs.
The 1121A audio analyzer provides fast, accurate measurements including frequency, AC or DC level, distortion, SINAD and signal-to-noise ratio. It also includes an audio source providing accurate low distortion signals over wide frequencies and level ranges.
