A measurement example of real time mode trigger function with the signal analyzer

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.

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.

Products introduction

Handheld signal analyzer MSA500 series

With Fast Fourier Transform (FFT) and conventional sweep systems, each strong point of both systems is usable.
