Chapter 1. Introduction

This document provides a detailed example of how to use the triggering subsystem of Platinum firmware for CMG-EAMs and CMG-NAMs. It also applies to integrated instruments and data acquisition systems incorporating modular EAMs, such as the CMG-5TDE networked accelerometer.

The example involves an EAM receiving data from two instruments. We will configure:

When a trigger occurs, we will compute:

The trigger summary configuration will include all five PGA values and the IJMA value.

Many other configurations are possible and it is hoped that this example will make clear the techniques required to build configurations to your own requirements.

The screen-shots are taken from a system running Platinum build 11205. Earlier builds do not include sufficient functionality. Later builds may show more options or minor differences in screen layout; the underlying principles remain the same.
