Smaart Operator Fundamentals Class Curriculum

Smaart Operator Fundamentals:

Standard Session Length: 2 Days, 8 hrs. ea. (16 hrs.  total)

Course Description: 

This course covers the fundamentals of setting up a Smaart measurement rig and using Smaart to make basic RTA, Spectrograph, Transfer Function and Impulse Response measurements. Special attention is paid throughout the course to the subject of how to make valid and useful measurements, as opposed to simply making cool squiggly lines appear on the screen.
