ABSTRACT:
Time/frequency skew between a plurality of simultaneously operated swept instruments is minimized by sharing a common master clock signal among the instruments and resetting the phases of internal clocking signals in each instrument to known states. Once reset, the clocking signals in each of the instruments operate in tandem. Consequently, the triggering latency period among all the instruments is uniform and subsequent triggered sweeps begin at substantially the same instant, providing accurate sweep tracking among a plurality of instruments.
