Why you should use LXI instruments in your next T&M system
Test & Measurement Designline Blogs  
3/9/2011   Post a comment
Once, combining separate instruments into an integrated test system meant GPIB interfaces. Today, a world of interface options are available, including Universal Serial Bus (USB) and LAN eXtensions for Instrumentation (LXI). Although there’s definitely a role for USB in T&M system integration, from the perspective of a test system integrator, I think LXI offers an edge.

Over the last 20 years, many different types of software applications have evolved to help relieve the test engineer from spending huge blocks of time writing code. Today, software products exist to create waveforms, analyze vector signals and make highly accurate measurements using advanced methodologies. These software tools can be integrated into a larger automated test environment and many instruments are now PC-based so the applications can now run directly on the instrument.

A virtual instrument reality check: Where's it really at?
Test & Measurement Designline Blogs  
11/12/2004   Post a comment
Leaps in processing power, I/O speeds, and local memory characterize today's system-ready test instruments. Agilent Technologies' program manager Marsh Faber tells why system-ready equipment is a major evolutionary phase in test, packing every bit as much impact as IEEE-488/GPIB did when it was introduced back in 1972. This in spite of so-called virtual instruments.
