The Pitfalls of Replacing Obsolete Instrumentation

摘要

An emulation strategy can help you incorporate new test instruments as build standards are upgraded. Overcoming test-equipment obsolescence is paramount in military and aerospace applications where test systems are supporting equipment with a service life of more than 20 years. However, replacing one or more obsolete instruments in a test system can have major consequences for the deployed Test Program Set (TPS). Even if a form, fit, and function replacement is made, a TPS or system software rewrite generally is inevitable.
