R&S FSH Power Meter
Performing Pulse Power Measurements (R&S FSH-K29)
Operating Manual 1173.6275.12 - 30 150
4.4.2.3 Averaging Traces
Selecting the trace mode
The Power vs Time result display provides two trace modes.
● The "Clear / Write" mode overwrites the trace data after each measurement.
● The "Average" mode forms an average over several measurement and displays
the data according to the selected detector.
When you select this mode, you can define the number of measurements over
which the trace data is calculated.
► Press the TRACE key.
► Press the "Trace Mode" softkey.
► Select the trace mode you prefer for the measurement.
Selecting the detector
When you are averaging traces, you can also select a detector. The detector defines
the way the measured data is evaluated and which data is displayed.
In the Power vs Time result display, you can select the "Average" detector or the "Max
Peak" detector. The "Average" detector displays the averaged measurement data,
while the "Max Peak" detector displays the highest values that have been measured on
each pixel.
► Press the TRACE key.
► Press the "Detector" softkey.
► Select the detector you prefer.
4.4.2.4 Triggering Measurements
In its default state, the R&S FSH starts a measurement on completion of the previous
measurement ("Free Run" measurements).
However, you can also perform triggered measurements with the power sensor. When
you choose to do so, the trigger event (the moment when the actual measurement
starts) is either a rising slope in the signal or a falling slope ("Positive" or "Negative"
trigger).
► Press the SWEEP key.
► Press the "Trigger" softkey.
► Select either the "Positive" or "Negative" menu item.
The R&S FSH stops measuring the signal until a trigger event occurs.
