Adjusting Synchronization Timing

Considering Trigger-to-Signal Delay Only

If the trigger line delay and the signal line delay are quite

smaller than the trigger-to-signal delay, you can ignore

trigger line length and signal line length. Suppose you are

using a digitizer to measure an analog signal from a DUT.

You have to program the edge location of the trigger signal

before the timing when the analog signal is output from

the DUT by the trigger-to-signal delay. The following is the

timing chart.
