rcles, with each representing a time offset, varies with the
complexity of the timing between the reference and input signals.
Integer multiples of reference rates. If you are timing input signals with rates that
are integer multiples of the reference rates, the instrument can measure the timing
deterministically and displays the relationship as one circle (offset) relative to
the cross-h
air. (See Figure 23.)

Such cases include timing an NTSC input (multiplier of 1) or a 525 SDI input
whose frame time is 33.36 ms (multiplier of 2), against an NTSC reference, which
hasaframetimeof66.73ms.
