Intermodulation distortion for both transmitters and receivers can be
measured by using a two-tone signal, as seen in the usual ARRL Lab reports.
I used informal shorthand in referring to the third and fifth order
intermodulation distortion products for the transmitter as IP3 and IP5, but
those are common terms.
IPx for the transmitter refers to Intermodulation Product rather than
Intercept Point, where x is the order of the product; hence IP3, etc.
