Chameleon is a simple, out-of-the-box, intuitive DAQ system with scalability to 1000+ channels.

PVI Systems, Inc. developed Chameleon – A powerful and intuitive data acquisition program – to take full advantage of DAQ hardware from NI (National Instruments). Chameleon’s unique architecture provides flexibility with an easy-to-use interface. Whether configuring basic channel count (10-100) or high channel count (1000+) systems, Chameleon provides the same intuitive interface allowing you to expand your system in any direction while using the same user-friendly software tools.

Chameleon is ideal for structural test (static, fatigue, and dynamic), design validation, and system health monitoring. Chameleon is being used across a wide variety of industries including Aerospace and Defense, Manufacturing, and Academia.

Chameleon PXI version 1.8.3 has been modified to enable high speed data acquisition above 2M/samples per second. Certain features and functions of Chameleon had to be modified to enable this much higher speed than normal.
