$400 · Hewlett Packard HP 3582A 2 channel audio spectrum analyzer

Hewlett Packard HP 3582A 2 channel audio spectrum analyzer in good operational and cosmetic condition. It covers 0.02Hz to 25.5 KHz per channel and can measure signal correlation / response / gain / phase / noise, etc. between 2 stereo channels. Pic 1 shows a 5 KHz sinewave at 0 dbV with relative 2nd and 3rd harmonic levels. Pic 2 shows the scale illumination turned down and the 2 pull out quick operational guides. Pic 3 shows the internal random noise source feeding a filter and the corresponding filter output spectrum with marker readouts. The last 2 pics show a 2 channel display of both low pass and high pass outputs of a selectable filter to simulate an audio speaker crossover. The display is bright and sharp. The operation / service manual is not supplied, but can be found on line. The reference pull out should get you started. This can be used to measure the THD of an audio signal. It's old school, but works fine. Local pick up only please.
