Objective
To determine the level of interfering signal which will generate harmonics in the tuner, causing interference 40 dB below a desired signal at the intermediate frequency (IF) output of a tuner under test.
The interfering input signal is referenced to a 75 ohm load and the tuner is then substituted for this load.
The procedure described below is appropriate for any interference generation within the tuner when a proper choice of filters, signal generators, and other equipment is made.
