Ed,

This is correct.  Single tone is the standard method used by the ARRL labs for SSB suppression.  Single tone SSB suppression on the FLEX-6000 Series is -80 dBc when measured in the lab.  We also have independent test lab confirmation.  The external lab typically only reports to -70 dBc in their tests.  Two tone tests are usually reported as a separate measurement.  73, Gerald
