Square Waveform Generation

To eliminate distortion due to aliasing at higher frequencies, the 33210A uses a

different waveform generation technique to create square waves. Square

waveforms are created by routing a DDS-generated sine wave into a comparator.

The digital output from the comparator is then used as the basis for the square

wave output. The duty cycle of the waveform can be varied by changing the

comparator's threshold.
