Introduction]%2$s[/h]
The HP339a was a state of the art (SOTA) distortion analyzer in the 1980s.
It is a full featured all-in-one product including a volt meter,
low-distortion oscillator, distortion analyzer, AM detector, and VU meter.
There was an in-depth analysis of low distortion oscillators
on DIYAudio on the following link:
<Low-disortion Audio-range Oscillator>
This was followed by a specific HP339a thread, linked here:
<HP339a>
This is a summary of those threads along with the links, conversations, and
posts, about the research and development that went into the suggested modifications to the venerable HP 339A.
