Transmit Signal Path

The transmit signal is configured via the operating mode that was selected by the user. When this mode

is selected, it sets those operating parameters for the FEC, and the FEC sends a signal to the high

voltage power supply (HVPS) to program one of the supplies (HVPS1 or HVPS2).

Once the signal is transmitted, it is received by the transmit pulsor (TP) which is a switching device that

will propagate the signal between different elements of the probe. The propagation of that signal

depends on the way in which the FEC programs the Front board RAM table.

The signal from the HVPS comes in to the TP; the TP then generates a signal to the probe (connected

to the Front board), in accordance with a command generated in Timing Pulse Generator (TPG). The

TPG operates according to tables in the RAM table - see
