CHAMELEON – Turnkey Data Acquisition Solution

Chameleon Data Acquisition

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

PVI 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 or high channel count 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 offers compatibility with a wide variety of NI controllers and data acquisition modules so you can configure a system to meet your specific application requirements. Have your system up and running in minutes, acquiring static and dynamic signals at multiple sample rates from a variety of sensor types.

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.

  • Out-of-the-box setup and operation
  • Mixed sensor configurations including microphones, accelerometers, bridge sensors, thermocouples, RTD’s, current sensors, and more
  • Data visualization, multiple traces and graphs, with live or pre-recorded data
  • Data export to popular file formats for post-test analysis
  • Channel alarms with visual, audible or digital output indicators

Hardware Platforms:

PXI, PXI Express

Provides power, cooling, and a communication bus for modular instruments or I/O modules. System runs without an external PC or lets you control your PXI system from desktops, laptops, or server computers. PXI hardware’s flexibility is ideal for use with applications that may change over time.

CompactDAQ (cDAQ)

Controls the timing, synchronization, and data transfer between NI C Series I/O modules and an external host.
CompactDAQ feature USB, Ethernet, or WiFi connectivity and come in multiple slot counts to provide the right amount of I/O for various applications. cDAQ hardware is ideal for applications where cost and hardware size is important.

Chameleon is ideal for use in a variety of test applicationsChameleon is ideal for use in a variety of test applications such as:

  • Structural, Acoustic, and Wind-tunnel testing (strain and bridge)
  • Thermal testing
  • Dynamic testing (vibration and acoustics)
  • Mixed sensor applications
