摘要 |
A programmable time advance circuit functions to offset the inherent delay in a printed circuit board test system (107) used to provide a clock signal (106) that exactly matches the clock signal (129) of a printed circuit board under test (103). A clock advance signal (104) is inserted into a phase locked loop (140) to advance the timing of the clock signal generator circuit (101) to compensate for the delay occasioned by the system components. |
