Exactly so."Harmonic distortion measurements are useful and significant up to
Now if the generator uses preemphasis and is distortionless including
the sine stimuli wed still have the fact that the distortion of the
analogue parts after the detector will have its distortion deemphased at
a rate of 6 dB/octave.

They say either use a wave analyser to measure each individual harmonic
or use a thd analyzer.
Right this measurement tells a LOT.It later proscribes using for the IM test 15,000 and 14,600 Hz at
No the two tone CCIF test makes for even WORSE figures than simple 15IM is a good test, but it still is ignoring all the spurs and
kHz stimuli will do.
AND ohhh yessss the spurs and garbage will be even greater with TWO HF
tones than one...............
