Measuring Pulsed Signals

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
An example of a pulsed signal is shown in Figure 2-11.

Pulse measurements are not recommended using Agilent E4412A
and E4413A power sensors.
