R&S FSH Power Meter
Performing Pulse Power Measurements (R&S FSH-K29)
Operating Manual 1173.6275.12 - 30 151
In case of triggered measurements, you have to define a trigger level by which the
signal must rise or fall in order to be recognized.
► Press the SWEEP key.
► Press the "Trigger" softkey.
► Select the "Trigger Level" menu item and define a trigger level.
In addition, you can define a trigger delay time. The trigger delay time defines a time
that must pass after the trigger event has occurred before the measurement starts. A
negative trigger delay time is called a pretrigger.
► Press the SWEEP key.
► Press the "Trigger" softkey.
► Select the "Trigger Delay" menu item and define a delay time.
When a trigger event occurs, the R&S FSH takes the delay time into account when
drawing the trace.
4.4.2.5 Selecting the Result Unit
In the pulse measurement application, the R&S FSH can display measured power in
relative units (dBm) or in absolute units (W).
► Press the AMPT key.
► Press the "Unit" softkey.
► Select the unit you prefer.
The R&S FSH adjusts the y-axis accordingly.
4.4.2.6 Scaling the Y-Axis
The functionality to scale the y-axis is similar to that of the Spectrum application.
For more information see "Setting a Display Range" on page 98.
4.4.2.7 Using Markers
The Power vs Time diagram supports markers. The functionality is similar to that of the
Spectrum application.
For more information see "Using Markers" on page 116 (note that marker functions are
not available in the Power Meter mode).
