Two-tone tests are often used to test SSB transmitter output power and gross linearity. The two audio tones used need to be non-harmonically related, and the RF output resulting from each tone individually should be the same amplitude. Then, the RF output of the two tones beating with each other can be used to easily on the scope measure power and look for gross linearity problems.
