I remember using Lissajous in the early 1970's when I worked for RCA servicing two way radios systems. I laugh at it now, but for about five (5) years using a Cushman service monitor and analog O-scope checking and calibrating tones. The lissajou was more accurate than the counters (we had) at that time.

As I recall. Lissajous figures only make sense if the two frequencies
have an integer relationship such as 2:1, 3:1, etc, otherwise all you
see is a jumbled mess. With a DSO (or frequency counter) you just
measure each frequency and ether's your answer.
