Abstract
System and method for synchronizing multiple devices coupled to a system timing module (STM) via respective first transmission media, wherein two or more of the respective first transmission media have different respective transmission times. The STM and devices share a common clock, in phase and with respect to a common reference. Each device is configured to transmit respective signals to the STM within a common clock cycle. Respective delays corresponding to the devices are determined based on the respective transmission times, where the respective delays are applicable to respective signals received from the devices to synchronize received corresponding pulses in the signals to within a common clock cycle. The respective delays are applied to respective signals received from the plurality of devices to synchronize received corresponding pulses in the signals to within the common clock cycle, after which the STM is operable to trigger the devices as a single device.
