THE SPIDER-80X DYNAMIC SIGNAL ANALYZER
SCALABLE DYNAMIC MEASUREMENT SYSTEM
The Spider-80X is a highly modularized, truly distributed, scalable dynamic measurement system. The Spider-80X excels in industries that demand quick and accurate real-time signal processing. It is ideal for a wide range of industries including machine condition monitoring, automotive, aviation, aerospace, electronics, and military.
Multiple Spider-80X modules are combined to form a high channel count system and are accurately synchronized through the IEEE 1588 protocol. Data acquired through all measurement channels are synchronized on the same time base. Accurate time synchronization results in excellent phase matching in the frequency domain between all channels, either on the same Spider-80X module or across different modules.
HIGH DYNAMIC RANGE
The Spider’s performance is the best in class with the highest dynamic range of any similar product. With patented technology, the Spider-80X achieves 150 dBFS input dynamic range (defined in the time domain). Each measurement channel detects signals as small as 6 μV and as large as ±20 V. Such high dynamic range eliminates the need for input range and or gain settings of traditional data acquisition systems.
A high speed floating point DSP manages the data input/output and real-time processing. The Spider-80X is also configured with RAM and onboard flash memory for mass data storage. Special thermal and low power designs eliminate the need for a cooling fan.
FREQUENCY RESPONSE FUNCTION (FRF)
The Spider-80X performs FRF analysis, a function which computes the structural response to steady-state osciliatory excitation. An important application of Dynamic Signal Analysis is characterizing the input-output behavior of physical systems. This is the domain of network analysis. With linear systems, the output is predicted from a known input if the Frequency Response Function of the system is known.
OTHER DYNAMIC SIGNAL ANALYSIS FUNCTIONS
The Spider-80X performs many dynamic signal analysis functions, including the following:
Data recording, Math (+,-,*,/), integration, differentiation, FFT, average, window, auto power spectra, cross-spectra, FRF, coherence, real-time filters, RMS, swept sine, limiting, alarm/abort and many more.
HIGH CHANNEL SYSTEMS
For systems configured with more than one Spider-80X module, the Spider-HUB is recommended. The Spider-HUB is a high performance industrial ethernet switch designed and manufactured by Crystal Instruments. With a total of ten Ethernet ports, the modular design of the Spider-HUB makes network planning easy, allowing for greater flexibility and quick expansion of multiple switches. Along with a choice of either front or rear wiring, its small size footprint and low energy consumption make the Spider-HUB suitable for a variety of industrial applications including high speed data acquisition and dynamic signal measurement.
