Synchronization 7 Analog Modules

to consider only trigger-to-signal delay. For the second

level, your application needs to consider trigger-to-signal

delay, trigger line length, and signal line length. For the

third level, your application uses some high speed analog

modules, and needs more detailed synchronization that

takes account of the synchronization uncertainty.

Currently the system software does not compensate the

synchronization timing skew to account for the trigger-to-

signal delay, trigger line length, and signal line length

automatically. Consequently, you have to consider these

delay factors to satisfy the accuracy requirement of

synchronization when you program the edge location of

the trigger signal. The following sections describe how you

can program the edge location of the trigger signal to

satisfy the required accuracy of synchronization.

• For the first level, see “Considering Trigger-to-Signal

Delay Only” on page 249.

• For the second level, see “Considering Trigger-to-

Signal Delay, Trigger Line, and Signal Line” on

page 250.

• For the third level, see “Considering Trigger-to-Signal

Delay, Trigger Line, and Signal Line” on page 250 and

“Synchronization Uncertainty” on page 254.

Before going into the methods of synchronization for the

three groups, the next section describes how to send a

trigger signal.
