The VPD-6830-DLY module series provides selectable amounts of delay, up to 1235 ns. The delay submodule includes a delay line with jumper-selectable delay (0 to 235 ns), fine delay adjust (5 ns range), and a socket for an additional fixed delay line that can be one of 200, 400, 600, 800, or 1000 ns increments. Different model numbers allow users to specify how much total delay is desired.
