Claim Text:
1. A system for sampling exhaust produced by an engine comprising: a first instrument measuring a first flow rate of the exhaust leaving the engine and generating a first signal including a first flow rate component indicating said first flow rate and a first instrument time stamp component associated with sampling at a first time; a second instrument measuring a pollutant concentration and generating a second signal including a pollutant concentration component indicating said pollutant concentration and a second instrument time stamp component associated with sampling at said first time and generating a tertiary signal including a component indicating a parameter that has been influenced by said first flow rate and including said second instrument time stamp component; and a synchronization module receiving and processing said first signal, said second signal, and said tertiary signal to determine a time relationship between said first signal and said second signal by comparing said first flow rate component and said first instrument time stamp component of said first signal to said influenced parameter component and said second instrument time stamp component of said tertiary signal.
