Interactive measurement software offers increased instrument connectivity

29 June 2005 Test & Measurement

National Instruments' SignalExpress is an interactive software environment for acquiring, comparing, automating and storing measurements on the benchtop. SignalExpress Version 1.1 delivers new high-speed digital I/O capabilities for mixed-signal design, validation and test as well as increased hardware support of NI modular instruments and data acquisition devices and other common standalone instruments. With the software, engineers can use virtual instrumentation on the benchtop to save time performing interactive analog and digital measurements.

"The new high-speed digital capabilities in SignalExpress 1.1 make it a great tool for performing common A/D converter measurements," said Mike Byrne, applications engineering manager at Analog Devices. "The unique SignalExpress interactive measurement environment enables designers to quickly and easily take mixed-signal measurements to characterise and validate their laboratory prototypes without the requirement to program. Furthermore, SignalExpress saves designers a significant amount of time by directly importing and comparing simulation signals with their live measurement data."

With the SignalExpress 1.0 release, NI introduced an interactive approach to taking benchtop measurements through virtual instrumentation. It featured an easy-to-use, drag-and-drop environment, which is ideal for engineers and technicians who require short time to measurement without programming. With SignalExpress 1.1 a suite of high-speed digital capabilities, including digital pattern generation, acquisition, processing, comparison and file I/O is introduced. With this functionality, engineers can accurately compare two digital patterns and convert digital patterns to analog signals for time-domain signal analysis and comparison. In addition, digital signals can easily be viewed by simply clicking and dragging them to the new digital data display in SignalExpress.

SignalExpress is available for Windows 2000/NT/XP.
