 Network Analyzers using PXI software

The position of the external trigger determines the moment when the Analyzer expects an external trigger signal — before the frequency setup or before measuring (ADC sampling). The frequency setup precedes the measurement for each frequency point.

Trigger Position

Function

Before Sampling

[default]

The trigger signal is expected before the ADC sampling when the frequency is already set. After sampling the Analyzer automatically transits to the next frequency (See figure below).

Before Setup

The trigger signal is expected before the frequency setup. The frequency setup starts when the trigger signal arrives (See figure below). After the frequency setup is completed, the Analyzer begins ADC sampling.

Before Setup, Point trigger ON

note

This function is intended for use in conjunction with the On Point trigger function. In case of the On Sweep trigger function, the trigger position will be performed only for the first sweep point.
