A measurement example of real time mode trigger function with the MSA500 si gnal analyzer is introduced.

Application

In real time mode of signal analyzer MSA500 series, p owerful trigger functions can be used.
By using these trigger functions, the signal can be measured immediately before and after the change has occurred in the waveform.

Solution

As a example, the trigger function is used for the me asurement of the change of carrier wave frequency of FM signal. In the measurement, the center frequency is set to a carrier wave frequency before change ,and the trigg er settings are channel trigger and slope FALL.

Figure:before change/after change

Trigger settings : Channel power trigger CH3, Trigg er slope FALL, Trigger point 50%.

It is possible to measure the waveform after and before the change.
