Lesson 3 – Synchronization of Analog Modules

Example of signal-to-trigger delay and its effects for sampling the

output of DAC:

Trigger-to-Signal Delay Example for DAC Testing

In addition, there are two kinds of signal delays that are caused by

the electrical length of signal lines on the DUT board:

Delay caused by the electrical length of the trigger line on the DUT

board between the digital pogo pin for the trigger and the trigger

input pogo pin of the analog module (trigger line delay)

Delay caused by the electrical length of the signal line between the

analog module's output/input pogo pin and the DUT input/output

pin (signal line delay)

Therefore, you can precisely synchronize the digital channel

operation and analog module operation by considering the

following three delay factors:
