(3) "Configure Trigger "button
Set the Delay, Width, and Blank of the selected trigger.
Delay & Width: 0 ~ 65535 Blank: 0 ~ 16777215
The total settable frequency is f = 1 / T, so 1 / ((65535 + 65535 + 16777215) * 10ns) =
Ref.) If you set Delay / Width / Blank as 0/0/0, it is total 50ns (10 + 40).
It is output at 20Mhz and each option increases by 1 as shown below.
