Spider DSA User’s Manual
65
Using a patented dual parallel A/D design, the Spider-81 is the first vibration
control system that achieves 160 dBFS input dynamic range. Each measurement
channel can detect signals as small as 6 μV and as large as 20 V. This design
completely eliminates the need for the input range or gain settings found on
traditional controllers.
The Spider-81B is designed to meet the requirements of basic vibration testing
applications. It has 4 inputs, 1 output, and 4 pairs of digital I/O.
Here’s a comparison table of all members of the Spider-81 series. For the full
hardware specification of each product, please refer to the hardware specification
sheets.
