Eimac's spec sheets show two-tone numbers ca. 65% of the single tone value.
As such, the 1200 watts of two-tone power would reprecent about 1800 watts
of carrier.
The only way I know of to measure two-tone PEP is with a calibrated scope
or spectrum analyzer. Use the scope to measure the peak voltage across the
dummy load and calculate power as E^2/Z.
