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. 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.
