4540 Power Meter

Quick Start Guide

The measured result is the average

power of the signal. Since the

graphic display would basically just

show a straight line, measurements

in Modulated Mode use mainly the

Numeric Display Mode.

The example shows a two channel

measurement displaying an average

power of -29.952 dBm at CH 1 and -

40.030 dBm at Ch 2.

Examples of Modulated Signals

CW Signal – Continuous Waveform with static

power level

On and Off State.

Amplitude Modulated Signal – Information is

contained in the amplitude level.

contained in the frequency shift.
