This section focuses on using the EDM to create a test for performing Order
Analysis and tracking. Based on the previous discussion, 3 measurements are of
prime significance in Order tracking. Order Spectrum and Order tracks with
phase, Continuous frequency spectrum or the FFT Spectrum and the Band RMS
Spectrum.
In this section, a detailed description on creating and measuring each of the
measurements is given starting with creating and setting up the basic properties
of an Order Tracking test. The following description is valid for both dedicated
tachometer compatible hardware units (7.5 and above) and non-compatible units
(7.4 and below) unless and otherwise specified. Henceforth, we designate the
dedicated tachometer compatible units as “7.5 Hardware” and the non-
compatible units as “7.4 Hardware”
Creating a Test
Order tracking is found under the “Dynamic Signal Analysis” section of the EDM.
Click on the Dynamic Signal Analysis to see the option for Order Tracking.
