Selecting Your Controller
Crystal Instruments (CI) offers more choices of vibration controllers than any other manufacturer. You can choose a very dedicated controller or a broad-application modular hardware platform. CI offers controllers with 2 to 512 input channels and 1 to 128 output channels. Every CI controller uses the same powerful Engineering Data Management (EDM) software providing exactly the same user-friendly control interface regardless of the selected hardware.
Each analog input is serviced by two 24-bit ADCs and a DSP implementing the cross-path calibration technology of our US Patent number 7,302,354 B2 to achieve better than 150 dB dynamic range, simultaneously measuring signals as small as 600 nV and as large as ±20 V, with time data retained in 32-bit single precision format (per IEEE 754-2008). 54 sample rates from 0.48 Hz to 102.4 kHz are provided with better than 150 dB of alias-free data from DC to 45% of any selected sample rate protected by steep 160 dB/Octave anti-aliasing filters. Successful control is all about dynamic range and no competitor can exceed ours.
All Crystal Instruments controllers are designed to function as networked servers. An Ethernet connection is used between the PC or laptop and the controller because it uses only differential signals and cannot cause a ground loop. In addition, Crystal Instruments employs Ethernet with IEEE 1588 Precision Time Protocol (PTP) time synchronization technology. Spider controllers and modules on the same network can be synchronized within 50 ns accuracy, even when hundreds of meters apart. This guarantees ±1° cross-channel phase match up to 20 kHz across the complete system. With this unique technology and high-speed Ethernet data transfer, the distributed components on the network truly act as one integrated system.
With the wide variety of Crystal Instruments controllers, you are sure to find one that is exactly right for you. Our most popular model is the Spider-81, a full-featured dedicated controller with eight inputs and four outputs. When more channels are a “must” consider the 16 input Spider-81A. If you are testing complex prototypes and need the utmost in flexibility, consider a Spider-80X-A35 dedicated enclosure and multiple Spider-80X modules. For a minimum-cost system ideal for academic applications look to the 4 channel Spider-81B. If your work centers on transportation Squeak and Rattle resolution, consider the Spider-81C, which allows you to control the shaker with your iPad® as you walk around and interact with the test specimen.
