A system and method of parameter measurement for a distributed computer system, the method including selecting a master unit; selecting slave units operably connected to the master unit on a bus, the slave units having a slave clock; determining slave unit latencies between the master unit and the slave units; generating slave unit synchronizing signals for the slave units, the slave unit synchronizing signals being adjusted for the slave unit latencies; synchronizing the slave clocks in response to the slave unit synchronizing signals; and measuring an operating parameter at the slave units at a synchronously determined time.
