-Instrumentation and data acquisition is focused on the collection of large volumes of [[ddsf:private:cookbook:​06_append:​glossary:​s:​sensor]] data in a short amount of time. One example, is an aircraft engine test bed ( for example, ​ [[https://​www.mtu.de/​e-papers/​MTU_ePaper/​Marketing/​Engine_test_beds/​epaper/​ausgabe.pdf | MTU Aero Engines]] where various sensors for things like temperature,​ pressure and vibration are place all around the inside and outside of an engine to collect data as the engine is running. ​+Instrumentation and data acquisition is focused on the collection of large volumes of [[ddsf:public:guidebook:​06_append:​glossary:​s:​sensor]] data in a short amount of time.

 Data acquisition is not limited to jet engines, but found in a number of industries. On a small scale, there might be eight to sixteen sensors collecting information maybe at the 10 hertz rate. On a large scale , such as testing a jet engine, there might be hundreds to thousands of sensors collecting data anywhere from 1 hertz to 20 kilohertz. ​ Data acquisition is not limited to jet engines, but found in a number of industries.

 Many of these data streams must be processed in real-time, in order to detect issues requiring immediate engine shutdown. Many of these data streams must be processed in real-time, in order to detect issues requiring immediate engine shutdown.

-A major benefit is to standardize an architecture around [[ddsf:private:cookbook:​06_append:​glossary:​d:​data_distribution_service_dds]]. These larger systems contain multiple data acquisition systems from multiple vendors developed at different times and locations. So, standardization on one [[ddsf:private:cookbook:​06_append:​glossary:​m:​midware]] and technology standard and interface allows for easy reconfiguration between different engine tests. ​+A major benefit is to standardize an architecture around [[ddsf:public:guidebook:​06_append:​glossary:​d:​data_distribution_service_dds]].
