HP Model 339A Distortion Analyzer

Ultra low distortion measurements
Built-in low distortion oscillator
Automatic
True RMS detection
Distortion Measurement Set
Ultralow distortion measuring system complete with total harmonic distortion （THD） analyzer, true rms voltmeter, ａnd sinewave oscillator. THD measurements over the 10 Hz to 110 kHz frequency band, including harmonics to 330 kHz. Also features built-in tracking oscillator.
Distortion Measurements

fundamental frequency range is 10 Hz to 110 kHz with 2 digit resolution
measurement range is 100% to 0.01%, （0 dB to -80 dB）
Oscillator

Frequency range is 10 Hz to 100 kHz with 2 digit resolution. Output level is variable from 4 V rms to 1 mV rms.

Oscillator distortion （ 〉600 ohm load, 〈3 Vrms）

10 Hz to 20 kHz 〈 -93 dB （0.0022%） THD
20 kHz to 30 kHz 〈 -85 dB （0.0056%） THD
30 kHz to 50 kHz 〈 -80 dB （0.01%） THD
50 kHz to 80 kHz 〈 -70 dB （0.032%） THD
80 kHz to 110 kHz 〈 -65 dB （0.056%） THD
