RadioProcessor
Appendix II: Arbitrary Waveform Generation
This document describes the shaped-pulse feature available on certain models of the RadioProcessor. If
equipped, the RadioProcessor is capable of arbitrary waveform generation on its analog output. This feature
allows for the following:
•
RF outputs can be shaped by an arbitrary waveform (for example, a sinc waveform).
•
RF outputs can be scaled by a constant value.
•
The RF output itself can be set to waveforms other than a sinewave (e.g., triangle wave, square wave,
etc.).
•
The shortest possible pulse is 66.6 ns, the longest is 693 days.
This allows, for example, the generation of soft pulses as shown below in Figure A2.1.
The AWG system is flexible and can be programmed with a wide variety of parameters. For example, as
shown in Figure A2.2 and Figure A2.3, pulse sequences that have pulses with multiple different amplitudes
can be generated and it is also possible to generate both hard and soft pulses in a single pulse program. The
shape of the pulse is not limited to a sinc-shape; it is user-loadable with any arbitrary waveform.
