Synchronization 7 Analog Modules

control the trigger-to-signal delay for the master and

slaves to the same time. Hence, uncertainty between

analog modules is eliminated even if you use different

master clocks for digital channels and analog modules.

Note that uncertainty in the trigger-to-signal delay

between a digital channel and analog modules remains

regardless of the use of the master trigger function.

The following figure is the block diagram for when the

master trigger function is used.

Figure 126 Master Trigger Function

Only when you use the master trigger function for the dual

high speed sampler, the trigger-to-signal delay for master

and slave modules changes according to the number of

slave modules as follows:

Trigger-to-Signal Delay = 70 ns + (N x 15 ns)

where, N is the number of the slave modules for one

master module.

For high speed AWGs, the trigger-to-signal delay for

master and slave modules is always fixed to 200 ns.
