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.
