Yes I know it is a standard IMD test. :) That is why I asked what
they were doing with two tones without a spectrum analyzer.
You left out the last part of my post.
"To do much else with it you also need a spectrum analyzer."
Here's my guess: it's a standard, which would be available in almost
any professional radio test lab.
Hence, it may simply be a convenient signal to use when performing
ALC and audio-pathway calibrations.
As is sometimes said, "The best thing about a standard is, sometimes,
that it's a standard. If it happens to be a _good_ standard, so much
the better!"
