Power Meter Operation
Measuring Pulsed Signals
To set the duty cycle:
1. Press System , A Input Settings. The current setting of the
Inputs
duty cycle is displayed under the Duty Cycle softkey.
2.To change this setting press Duty Cycle . The power meter displays the duty cycle in a pop up window. Modify this value (see below) until the desired duty cycle is displayed.
■Use 
or 
to modify the digit on which the cursor is currently positioned.
■Use 
or 
to move to other digits.
3.To confirm your choice press % .
4.Duty Cycle Off On is automatically set to “On” when a value is entered using Duty Cycle .
Duty cycle can be disabled and
Duty Cycle Off On.
Note | Pulse power averages out any aberrations in the pulse such as |
| overshooting or ringing. For this reason it is called pulse power |
| and not peak power or peak pulse power. |
| In order to ensure accurate pulse power readings, the input signal |
| must be pulsed with a rectangular pulse. Other pulse shapes (such |
| as triangle, chirp or Gaussian) will cause erroneous results. |
| The pulse power on/off ratio must be much greater than the duty |
| cycle ratio. |
