Interchangeable Virtual Instruments (IVI) is a standard for instrumentation drivers that is designed to reduce the time and effort needed to integrate measurement devices into new or existing systems. It does this by providing a standard application programming interface (API) that defines common measurement functions. This is, in turn, provided by a standard set of shared components that must be used by all compliant drivers and ancillary software. These components provide services to drivers and driver clients that need to be common to all drivers.
In early 2012, engineers at a prime aerospace manufacturer were assigned the task of replacing several existing integrated test adapters (ITAs) used to test multiple line replaceable units (LRUs) belonging to an Air Force program. One goal was to replace the existing ITAs with as much commercial off-the-shelf (COTS) technology as possible.

The Sorensen SG Series is designed for exceptional load transient response, low noise and the highest power density in the industry. With a full 15 kW available down to 20VDC output in a 3U package the SG Series leads the industry in power density. The power density is enhanced by a stylish front air intake allowing supplies to be stacked without any required clearance between units.
The Sorensen™ SGX Series is the next generation of our successful SG Series of programmable DC power supplies. Like the SG Series, the SGX Series has exceptional load transient response, very low noise, and high power density. What sets the SGX Series apart is the new touch screen display. This new feature makes the Sorensen SG Series of programmable DC power supplies even easier to use.
For multi-channel data acquisition systems, getting the correct readings in the correct timed order is crucial. System designers have two options for acquiring data in a deterministic fashion. They can use a real-time operating system (RTOS), that has a known buffer delay/ processing order or acquire data with a time-stamp for every sample and use precise hardware triggers and an accurate clock.
