R.F power measurement
Power accuracy using the 848X sensor family varying from +/-1.2 % at 1mW
Up to 10W using the coupler up to 1GHz at +/- 1.8% and 100W using the attenuator at +/-2.0%.
Amplifier power sources --
35W from 10KHz to 150MHz
3W from 150MHz to 1000MHz
The best uncertanty/resolution is +/- 0.1dB per 10db step
over the range
100KHz to 2.9 GHz (indipendant of miss-match uncertainty). Using a
NIST certified attenuator with the DC substitution power ratio as back-up.
