A system for providing signal trigger pulses comprises an equivalent time sampling unit providing transmit and receive trigger pairs, and a control unit controlling the equivalent time sampling unit to provide pseudorandom delay length variations between the trigger pairs.

Systems and methods for providing trigger timing

A variable delay apparatus comprises a calibrating unit receiving a signal from a variable delay unit and from a plurality of fixed delay sources, the calibrating unit comparing the signal from the variable delay unit with a plurality of signals from the fixed delay sources to control operation of the variable delay unit over a delay range independently of environmentally-induced drift.
