[TenTec] Voltages on 50 ohm Dummy Load

Hello All,

I need to calibrate the watt meters on my Titan, Omni VI+ and 253 Tuner.
I have a Drake 2 kw PEP dummy load and a nice 200 mHz storage scope.  In
order to measure output, should I measure RMS, or Peak voltage, (if I
use a sine wave input), and what are the voltages for 100 watts and the
legal limit?

My guess for a sine wave would be that for 1500 watts PEP out, I should
see a peak voltage of about 274 volts, and 70 volts for 100 watts, if
the dummy load is truly 50 ohms.  Is this correct?

Thanks,
Barry
