The Tektronix TDS Oscilloscope is a superb tool for acquiring, displaying, and measuring waveforms. Its performance addresses the needs of both benchtop lab and portable applications.
Limit Testing
The TDS Oscilloscope provides limit testing, which can automatically compare each incoming or math waveform against a template waveform. You set an envelope of limits around a waveform and the oscilloscope finds waveforms that fall outside those limits. (See Figure 3ﾖ82.) When it finds such a waveform, the oscilloscope can generate a hardcopy, ring a bell, and stop and wait for your input.
Waveform Math
The TDS Oscilloscope provides a means for you to mathematically manipulate your waveforms. For example, you might have a waveform clouded by background noise. You can obtain a cleaner waveform by subtracting the background noise from your original waveform.
Fast Fourier Transforms (FFT)
The Advanced DSP Math capabilities of the TDS Oscilloscope include taking the Fast Fourier Transform (FFT) of a waveform. This section describes FFTs and how to set up the oscilloscope to display and measure FFTs.
The FFT allows you to transform a waveform from a display of its amplitude against time to one that plots the amplitudes of the various discrete frequencies the waveform contains. Further, you can also display the phase shifts of those frequencies. Use FFT math waveforms in the following applications:
