► 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.
5.4.2.4 Triggering Measurements
In its default state, the R&S ZVH 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 ZVH stops measuring the signal until a trigger event occurs.
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 ZVH takes the delay time into account when
drawing the trace.
