Abstract
A pair of programmable state machines may be included in a transmitter integrated circuit of a scanner (e.g. a body scanner) to control the sub-circuits of the transmitter integrated circuit. The first programmable state machine may be used to control the signal processor of the transmitter that facilitates generation of a signal to be transmitted at a target, such as a user to be scanned. The second programmable state machine may be used to control the transmitter's selection of a transmission channel for transmitting the signal in which provides the signal to be transmitted to an antenna. Further, the receiver integrated circuit of the scanner may include a similar pair of programmable state machines for controlling the receive signal processor and receiver of the receiver integrated circuit. The inclusion of the state machines can reduce both the scan time and the circuit complexity of the scanner.
