Conducting RF measurements
The following sections describe how to conduct RF measurements.
Channel power
he Channel Power measurement is a common test used in the wireless industry to
T
measure the total transmitted power of a radio within a defined frequency channel. It
acquires a number of points representing the input signal in the time domain,
transforms this information into the frequency domain using Fast Fourier Transform
(FFT), and then calculates the channel power. The effective resolution bandwidth of
the frequency domain trace is proportional to the number of points acquired for the
FFT.
The channel power measurement identifies the total RF power, power spectral density,
and Peak to Average Ratio (PAR) of the signal within the channel bandwidth.

Internal: Uses a 10 MHz internal clock
External: Uses external 10 MHz, 13 MHz, or 15 MHz clock automatically set
by the instrument
GPS: Uses a built-in GPS as a frequency and timing source
NOTE
Make sure to set Frequency Reference for all measurement mode in 5G DSS
Signal Analyzer to sync the proper clock source.
