7. Power meter
Level 0,5 ... 20 W (up to 50 W - w/ external attenuator FAD-2, up to 100 W - w/ FAD-3, by agreement with the Customer) Note that when using the FAD type fix attenuators or analogs for measuring parameters of radio transmitter with the output power above 20 W, the power value measured by the device must be multiplied by the attenuation (fading) ratio of the attenuator by the formula Ratt=10 to the power of Ratt, dB/10)
Error < [10+(Pk/Pmst)] %
