# TDS3FFT Tektronix Module Used

**Additional Features:**

-   For TDS3000 and TDS3000B Series of Oscilloscopes

The FFT application module adds FFT (Fast Fourier Transform) measurement capabilities to your oscilloscope. The FFT process mathematically converts the standard time-domain signal (repetitive or single-shot acquisition) into its frequency components, providing spectrum analysis capabilities.  
Being able to quickly look at a signal’s frequency components and spectrum shape is a powerful research and analysis tool. FFT is an excellent troubleshooting aid for:

-   Testing impulse response of filters and systems
-   Measuring harmonic content and distortion in systems
-   Identifying and locating noise and interference sources
-   Analyzing vibration
-   Analyzing harmonics in 50 and 60 Hz power lines

**FFT Windows**  
Four FFT windows (Rectangular, Hamming, Hanning, and Blackman-Harris) let you match the optimum window to the signal you are analyzing. The Rectangular window is best for nonperiodic events such as transients, pulses, and one-shot acquisitions. The Hamming, Hanning, and Blackman-Harris windows are better for periodic signals.

**Analyze Repetitive, Single-Shot, and Stored Waveforms**  
You can display an FFT waveform on any actively-acquired signal (periodic or one-shot), the last acquired signal, or any signal stored in reference memory.

**dB or Linear RMS Scales**  
The FFT vertical graticule can be set to either dB or Linear RMS. A dB scale is useful when the frequency component magnitudes cover a wide dynamic range, letting you show both lesser and greater- magnitude frequency components on the same display. A Linear scale is useful when the frequency component magnitudes are all close in value, allowing direct comparison of their magnitudes.

**Time Signals and FFT Waveforms Displayed Together**  
The time signals and FFT waveforms can be shown together on the display. The time signal highlights the problem; the FFT waveform helps you determine the cause of the problem.
