Spider-20 Handheld Dynamic Signal Analyzer Handheld Field Testing Solution Spider-20 is a compact yet powerful dynamic signal analyzer and digital data recorder. It provides four 24-bit precise high-fidelity input channels, and a unique software-selectable tachometerinput/signal-source output channel (all using conventional BNC connectors). Each input is individually programmable to accept AC or DC voltage or output from an IEPE (ICP) sensor with built-in electronics. Spider-20 is a diminutive 5.3 x 4.3 x 1 inch tool weighing only 18 ounces. It has only three push-button controls and five...

Analog Signal Analog High Pass Filter (Op�onal) An�-Aliasing Filter A/D Converter A/D Converter Synchronous Clock High Precision Front-end Design The Spider-80X/Xi 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...

8 Strain Gage Inputs Output Channel Power Power Input Reset Bu�on Ethernet Data Port Master/Slave Switch The Spider-80SG Strain Gage Measurement System Strain Gage Measurement The Spider-80SG Strain Gage Module The Spider-80SG/SGi is a front-end in the Spider-80X/Xi hardware family platform. It is a high precision, general purpose data acquisition device featuring strain gage functionality. This device can be used in a variety of physical and measurement tests. The Spider-80SG can acquire data from a strain gage or a wide range of sensors. With the help of precision excitation voltage, the...

Dual Modes of Excitation The Spider-80SG is equipped with dual excitation modes. There is an option for Precision Excitation Voltage of ± 2.5 V or ± 5 V that can be used to excite a strain gage or a strain gage based sensor and to accurately measure the minute change in resistance. It is also equipped with a user configurable DC power supply of 2.5 V, 5 V and 10 V which can be used as an excitation voltage for a wide variety of sensors. Spider- 80SG Highlighted Features: • 8 Strain Gage/General Purpose Inputs Per Front-end • 24-bit ADC Channel • Supports Multiple Measurement Quantities...

General Data Acquisition & FFT Spectral Analysis Comprehensive Data Acquisition with the Spider System The FFT Spectral Analysis provides comprehensive data acquisition and FFT analysis functions. Acquisition Mode controls how the data is acquired block-by-block and processed with the signal analyzer functions. These time blocks can be either gap-free, overlapped, or with gaps, depending on the acquisition mode selection. Sampling Rate can be set from control panel directly. 54 sampling rate stages available and can be changed without stopping data acquisition. 3D waterfall processing...

Acquisition Mode includes free-run, continuous after trigger, single shot with trigger, single shot without trigger, auto-arm trigger and manual-arm trigger. Multi-Resolution Spectrum provides the ability to use different spectral resolutions at low frequencies and high frequencies within the same spectrum. When analysis requires a denser frequency resolution in the lower frequencies compared to the higher frequencies, multi-resolution spectrum can be used. The need for a higher block size (for better frequency resolution) is eliminated because the spectral resolution is eight times higher...

The Spider has strong System Failure Protection. With its Power Loss Emergency Shutdown, when a power loss is detected, the system will save all test data into non-volatile flash memory and safely shut down. With its Ethernet Connection Loss Detection, when a network loss is detected, the system can be configured to either save all data and ramp down the test or continue running the test in Black Box mode. Each Spider has 4 pair of DIO ports which is used to send and receive low level electrical signals to and from other devices to coordinate their operation during a test. The output...
