The Agilent 332A Distortion Analyzer is a solid-state instrument for measuring distortion and ac voltages. The 332A includes a high impedance AM detector which operates from 550 kHz to greater than 65 MHz. Distortion levels of 0.1% to 100% full scale are measured in seven ranges for any fundamental frequency from 5 Hz to 600 kHz., harmonics are indicated up to 3 MHz. The high sensitivity of these instruments requires only 0.3 V rms for the 100% set level reference. An output is provided at the OUTPUT connectors for monitoring the distortion with an oscilloscope, a true rms voltmeter, or a wave analyzer. The instruments are capable of a dc isolation voltage of 400 volts above chassis ground.

The transistorized voltmeter contained in the 332A can be used separately for general purpose voltage and gain measurements. The voltmeter has a frequency range of 5 Hz to 3 MHz (20 Hz to 500 kHz for 300 µV range) and a voltage range of 300 µV to 300V rms full scale.

The AM detector included in the 332A is a broadband dc restoring peak detector consisting of a semiconductor diode and filter circuit. AM distortion levels as low as 0.3% can be measured on a 3 V to 8 V rms carrier modulated 30% in the standard broadcast band, and lower than 1% distortion can be measured at the same level of the carrier up to 65 MHz.
