TESTED WORKING. NOT CALIBRATED. The HP 239A  Low Distortion Oscillator   The 239A low distortion oscillator appeared in the 1979 catalog. It would be the very last, fully analog signal source produced by HP. The 239A Oscillator is electrically similar to the built-in oscillator used in the HP 339A distortion measurement set. The 239A covers from 10 Hz to 110 kHz in 4 overlapping decade ranges with 2 digit resolution. The output level is variable from 1 millivolt to 3.16 Vrms into 600 ohms. The unequaled characteristic of the HP 239A is its distortion specification. For a 3 volts output, up to 20 kHz, the signal distortion is below -95 dB, which is equivalent to a 0.0018 %THD ! In the upper part of its frequency coverage, up to 110 kHz the distortion stay specified below -70 dB (0.032% THD) These unsurpassed characteristics make the HP 239A, a still today highly appreciated reference for distortion measurement on the audiophile test bench.
