I need to build a better two-tone audio generator so that I can improve my ability to make IMD measurements. In this episode, I choose a new design, build and bring-up the PCB.

👍 As a side note: a Wien bridge oscillator doesn't necessarily needs lamps as it is typically suggested. Usual 1N4148 work just fine. My version of the schematic can be found by the query "two tone oscillator eax me pdf".

Yep, I should have commented on that when I was talking about the lamps. I built a Wien bridge a while back that used 1N4148's that I matched to within a few millivolts drop.

You could use a sound card with audio analyser software or FFT on your oscilloscope to check for audio IMD first.

Hi have you any of the board for sale or can i buy a copy of your design and get a few boards printed as this is beyond my cabilities. Thanks in advance.
