HGL Dragonfly Acquisition Card

Dragonfly Acquisition Card :: Front  Dragonfly Acquisition Card :: Back

 

The Dragonfly8 acquisition cards are robust, highly accurate acquisition cards ideal for vibration and sound recording and measurement. Capable of sampling at up to a 250kHz sample rate, these acquisition cards were developed in response to a need for a small, portable, and highly accurate acquisition card within the aerospace industry. With multiple signal conditioning options, flexibility is a key component in the design of these cards. Controlled over Ethernet, the Dragonflyacquisition cards are network based by design, allowing for multiple cards to be used simultaneously with ease.
