Spider-80X Dynamic Measurement & Vibration Control

High Precision Front-end Design
The Spider-80X analog input channels provide extremely high precision measurements. Each channel has single-ended or differential AC or DC input coupling. It can also provide IEPE (ICPTM) input mode (AC coupling with a 4 mA constant current from a 22 VDC source) for use with industry-standard accelerometers with built-in amplifiers. The ability to read TEDS (Transducer Electronic Data Sheet) identification from the attached transducer completes the channel’s compliance with IEEE 1451.4. Each channel provides an unprecedented dynamic range of 175 dBFS. This is accomplished by applying two 24-bit analog-to-digital converters to each channel and combining their outputs in accordance with our United States Patent number 7,302,354.

In the Spider-80X, built-in charge amplifiers are available.

Time Accuracy and Synchronization
The Spider-80X complies with the IEEE 1588 Precision Time Protocol (PTPv2). It also supports integration with a grandmaster clock, enabling sub-microsecond time-stamping accuracy. This allows for multiple physically disconnected Spider-80X units to be synchronized within a 100-nanosecond time accuracy. The Spiders can maintain a phase match of less than 1 degree making it possible to compute frequency response functions, cross-spectra, autocorrelation, and various other signal analyses with high precision.

Black Box Mode
Black Box mode enables Spider-80X operation without a PC. In this mode, a PC is used only to configure the control system before the system starts operation and to download data after the test is completed. During the test, the data acquisition system operates autonomously, according to a preset schedule or in response to external events such as input trigger or digital input.

Simple Network Connection
Ethernet connectivity allows Spiders to be located far from their host PC. This distributed structure greatly reduces noise and electrical interference in the system.

• Spider-HUB Ethernet Switch
  The Spider-HUB Ethernet switch made by Crystal Instruments supports the latest IEEE 1588v2 technology. The Spider-HUB guarantees time-stamping accuracy within 50 nanoseconds and can be configured for 1588v2 Master, Boundary Clock, and Transparent Clock functionality. Accurate phase match between all measurement channels across the modules are guaranteed.

• Spider-NAS Storage Device
  The Spider-NAS (Network Attached Storage) is a dedicated storage device designed to work with Crystal Instruments Spider front-ends, including the Spider-80X and the Spider-81. Each Spider-NAS device supports up to eight Spider front-ends to collect both streaming time waveform data and spectral data. An Ethernet connection in back connects to a computer for data download and configuration. At the center of the Spider-NAS sits a removable 250 GB solid-state drive (SSD) with a storage upgrade option of 2 TB. This SSD not only provides greater shock protection than a classic hard drive but it also features a faster boot up time (less than 15 seconds) and is particularly energy efficient.

• Spider-80SG Strain Sensing Device
  Has the same mechanical form factor as the Spider-80X. These two systems can combine into a system that measures various dynamic signals, including strains or other sensors requiring excitation.

• Spider-80Ti Temperature Measurement System
  The Spider-80Ti has the same mechanical form as the Spider-80X. It is a temperature DAQ that be combined with the Spider-80X to form a system that can measure various dynamic signals alongside temperature data.
