ABSTRACT:
A technique for performing frequency margin testing of communications system circuit boards incorporates a frequency agile clock source on a communications system circuit board. The clock source may be programmed to operate the circuit board at a nominal operating frequency and at frequencies suitable to characterize actual and/or apparent frequency tolerances of the circuit board. The technique maintains transmission line integrity of the on-board clock.
