Acquire, Analyze, Import Vibration Data

Reproducing actual field vibration data is a key feature of the APEX Series Vibration Controllers! It provides four distinct and important choices for analyzing and importing data for creation of random, transient shock, and time replication acceleration control (TRAC) tests. Collecting data and importing the information into the controller is accomplished by using the Signal Analyze/Transient Capture and Data Acquisition modes, or by importing stored ASCII file data. The Import Data Manger provides guidance and extensive editing options for optimizing the new test. The resulting test reference (time or frequency spectrum) can then be performed at the vibration test system.
