Techniques for Precise Power
Measurements in the Field
Using FieldFox Handheld Analyzers
This application note will discuss techniques for measuring average and peak power
and the associated equipment options available for field testing. As there is a range
of instrument types that can measure power, this application note will focus on the
two most widely employed RF/microwave instruments, namely, the power sensor
and the spectrum analyzer. Measurement examples will include signals such as CW,
pulsed and digitally modulated waveforms. It is important to understand the accuracy
and limitations of each instrument including factors that can affect the instruments'
performance in the field. Comparisons between different power sensors and spectrum
analyzers will be presented.
