Advanced Setup Options
Overview
Introduction
This chapter describes the options available to users with applications that require
advanced setups. Although PowerVisa is designed to capture data no matter what the
setup is, users are able to configure combinations of setups unique to their task
applications.
Definitions
Setup: A pre-set condition of parameter thresholds and waveform capture settings for
each channel that determines what will constitute an event and what waveform data
will be saved when this event occurs.
Event: An event occurs when a pre-set or programmed threshold is crossed. Events
result in a contiguous collection of cycles that is saved into memory. An event consists
of pre-trigger cycle(s), trigger cycle(s), and post-trigger cycle(s).
Parameter threshold: A value that the PowerVisa compares to a measurement to decide
if an event occurs. Also called a limit. For example, if the input voltage is measured as
135 Vrms, and the parameter threshold for voltage is 132 Vrms, PowerVisa saves this
limit crossing to memory as an event.
