7 Analog Modules Synchronization

252 System Reference, January 2001

Adjusting Timing at DUT Pin

Assuming the DUT pin as the reference point of timing,

you have to compensate the signal line length, which is

between the DUT pin and pogo pin of the analog module,

when you program the edge location of the trigger signal.

For the AWG, you have to move the trigger signal edge

backward by the trigger line length plus the trigger-to-

signal delay plus the signal line length from the reference

point. As a result, the analog signal generated by the AWG

arrives at the DUT pin at the desired timing.
