Video: Basics of using FFT on a CRO

[VK4GHZ]

From W2AEW:

This video (by request) gives an overview of how to the FFT Math function on the Tektronix TDS2000 series oscilloscope. (same applies to the TDS1000).
A brief review of FFT fundamentals is given, followed by a demonstration of using the FFT function and controls, ending with a description of the mathematical relationships between the scope settings and the FFT results.
More modern scopes will have different (easier to use) controls for the FFT than this 12+ yr old scope, but it is instructive to understand the operation of this feature.
