Measuring Pulsed Signals

The power meter can be used to measure the power of a pulsed signal. The

measurement result is a mathematical representation of the pulse power

rather than an actual measurement (assumes constant peak power). The

power meter measures the average power of the pulsed input signal and

then divides the measurement result by the duty cycle value to obtain the

pulse power reading. The allowable range of values is 0.001 % to 100 %.

The default value is 1.000%.

If duty cycle is enabled then “Dty Cyc” is displayed.

Note Pulse measurements are not recommended using Agilent E4412A

and E4413A power sensors.

An example of a pulsed signal is shown in Figure 2-10.
