4-11 Channel Power Measurement

Channel power measurement is one of most common measurements for a radio transmitter.
This test measures the output power, or channel power, of a transmitter over the frequency
range. Out-of-specification power measurements indicate system faults, which can be in the
power amplifiers or in filter circuits. Channel Power measurements can be used to validate
transmitter performance, comply with government regulations, or to keep overall system
interference at a minimum.
Frequency and span settings for many signal standards can be automatically set by pressing
the key and then the
