900 Series

Data Physics 900 Series Vibration Control and Signal Analysis Systems

The Data Physics 900 Series Vibration Controllers integrate innovating vibration control algorithms with a new distributed real-time signal processing engine to provide extraordinary vibration control performance. With a modular, gigabit Ethernet architecture, the 900 Series can be expanded to over 1,000 channels for laboratory use.

The SignalCalc test suite includes a broad range of vibration control and dynamic signal analysis tools and provides a seamless environment for simultaneous vibration control and signal analysis.  The 900 Series Vibration Controller applications include:

• Random Vibration Control
• Sine Vibration Control
• Shock Vibration Control
• SRS Synthesis Control
• Mixed Mode Control (Sine on Random, Random on Random)
• Sine Resonance Search and Dwell Control

Simplified Test and Analysis

The SignalCalc 900 Series user interface simplifies test setup and run-time operations. Enter the test profile and the configuration wizard automatically sets up associated control and measurement parameters. Import shaker parameters from a large database of standard models to verify test feasibility. All setup, project, test article, and customer information is saved along with measurement data in a database. Easily search for data from different test runs and test types for analysis and report generation.

• Manage tests and data using the built-in relational database
• Streamline testing by running multiple simultaneous real-time measurements
• Define custom real-time signal processing functions using mathematical operations, including, integration, differentiation, addition, subtraction, multiplication, division, matrix operations, filters (low pass, high pass and bandpass), Fourier Transform, Inverse Fourier Transform
• Generate high-quality custom reports

Modular, Scalable Hardware

The new Abacus 900 Series hardware platform is a powerful, real-time, distributed digital signal processing system. The Gigabit Ethernet network architecture allows the systems to be used independently or combined to create larger systems with over 1,000 channels. Systems are comprised of channel cards with up to six channels per card. Two channels on each card are reconfigurable by the user as inputs, outputs or tachometers allowing the system to be configured as needed for each test.

 

• Up to 216 kSamples/s for 80 kHz of alias-free bandwidth
• 24-bit analog-to-digital conversion with up to 150 dB dynamic range
• Channel-to-channel phase accuracy of better than 0.5 deg at 40 kHz

The Abacus 901 is an ultra-portable system well-suited for both laboratory and field use.  Multiple systems can be combined for larger tests.

• Six channels (input/output/tach)
• Passive cooling for silent operation
• Power over Ethernet
• Remote and autonomous operation

The Abacus 906 is a compact, durable system for both lab and field applications. Multiple 906 and 901 systems can be combined to create larger systems.

• Up to 36 channels per chassis – expandable to over 1,000
• Flexible input/output/tach configuration
• Quiet mode for acoustic applications

Enhanced Signal Analysis Tools

The SignalCalc 900 Series has a unique ability to add signal analysis measurements to a vibration control test. For example, narrowband FFT, third octave, and histogram measurements can run simultaneously with the vibration control test. These measurements are configured using independent sample rates, bandwidths, block sizes, etc. Independent acquisition, analysis and control systems with separate hardware are no longer required. Signal analysis measurements are immediately available, removing the delay of waiting for post-processing of recorded data.

The 900 Series Dynamic Signal Analyzer software offers signal analysis solutions for a wide range of dynamic testing applications:

• General FFT Analysis
• Data Acquisition and Waterfall Analysis
• Throughput Recording & Playback Analysis
• Structural Analysis
• Acoustic Analysis
• Rotating Machinery Analysis
• Environmental Test Data Analysis

User-Defined Real-Time Signal Processing

SignalCalc 900 Series signal processing tools set includes user-defined custom signal processing. These algorithms are processed during the test in real-time using the embedded digital signal processors in the 901 hardware. The results of these algorithms may be displayed during the test and saved with test data.

User-defined signal processing options include:

Channel Math – Creation of “User Channels” using mathematical operations on time-domain signals from input channels: Integration, Differentiation, Addition, Subtraction, Multiplication, Division of Channel, Matrix Math, Low Pass, High Pass, and Band Pass Filtering.

Signal Math – Creation of “User Signals” using mathematical operations on processed time and frequency domain signals: Addition, Subtraction, Multiplication, Division, FFT, IFFT, CFFT, ICFFT.

Network Access to Multiple Tests
Multiple workstations can connect and disconnect to a test in process. With proper permissions, users can remotely connect, configure, run, transfer control, and monitor multiple tests.
