Turnkey Vibration Acquisition and Analysis Hardware Running on Easy to Use, Versatile, and Powerful Software

Compact and rugged, the 900 Series hardware is designed for the most demanding field or lab applications. With a modular, distributed architecture, the 900 Series can be expanded to over 1,000 channels for laboratory use.

906 901 and Quattro


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

Simplified Test and Analysis

The new SignalCalc 900 Series software makes the process of defining a test, making measurements, analyzing data and generating high-quality reports easier than ever before.  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

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.

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.

1 Math Channels

Math channels appear in setups, graphs, and data with physical channels. All related signal processing for the measurement or control are also performed on Math Channels.

2 Combine Math Operations

Use multiple math operations in a single function to build virtual channels.

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.

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.

Custom Reports and Data Review/Export

Fully Customizable Plots

Include readouts including test parameters, customer and test article name, operator, test time, etc

Overlay Data

Data from one or more runs can be overlaid in Review Mode within seconds.  The overlaid plots can be placed in a report.

Data Export

Sweep data can be exported automatically at the end of a test.

Create Custom Report Templates in Microsoft Word

Create a report template in Microsoft Word and have SignalCalc 900 populate the report parameters, plots, and images automatically after each test (DP900-68)

Images and Media

Attach images of the test article or setup and have them printed in the report

Generate Reports Anywhere

Generate Reports on the PC that conducted the test, or on any networked PC
