Best Practices for Open Technology Test Stands

Posted by Kari Grosser on Aug 18, 2016 10:30:00 AM

Test stands are used to acquire, store and analyze data from a wide variety of sensors and devices. As such, they are required to have certain attributes:

  • can interface to many different type of sensors

  • can provide signal conditioning

  • can support many different communication protocols

  • can store large amounts of data

  • can host the wide variety of software programs used to view, analyze and distribute the acquired data

The main components of a test stand are the operator interface, the PC or other data processing and storage device, and the I/O. Best practices are to use open systems and components to configure the test stand because this provides the best price/performance ration and the highest degree of flexibility. 

Using a PC as the data processing and storage device provides the utmost in terms of an open system, and it also helps designers provide the attributes listed above. PC-based data acquisition cards can interface to many different types of sensors, and PCs can also support multiple communication protocols. A PC can store large amounts of data, and it can host most any data acquisition and analysis software program, like this PC-based acquisition software.
