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. 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 HP ECP-series
power sensors.
An example of a pulsed signal is shown in Figure 2-6.
