Optional timing module: it distributes clock, trigger and synchronization across the units, with a system clock of 20, 50 or 100 MHz selected by the part number. It accepts an external GPS/GNSS reference and a low-jitter analog clock, and reports which source the system clock is locked to. Configuration by DIP switches or serial port.
