Small Portable Measurements
Being away from your home base also means you want to be sure to collect all the data you think you need, plus enough extra data to prevent a repeated trip. In these types of situations it is always helpful to be able to collect the data of interest and all the possible supporting data.
This often means a combination of analog data, such as acceleration and sound, along with digital data from the CANbus that brings in all the embedded data of the system.
"When faced with
testing scenarios which present with either relative motion between
components of interest or large physical dimensions, distributed
measurement systems offer a way to accomplish the measurement
In these situations, a cluster of small battery powered systems synchronized over GPS can offer the most efficient solution."
This fuller picture often enables the source of unwanted behaviors to be traced and resolved versus only having the symptomatic data without an explanation.
For this holistic picture to come together, the digital and analog data needs to be synchronized not only channel to channel but potentially between multiple systems.
