Data Physics is pleased to announce the release of Version 1.6 software for the SignalCalc 900 Series Signal Analyzers and Controllers. This version features the latest generation of Stepped Sine, as well as numerous new features and improvements — along with enhanced ease of use capabilities. 

To access the full 1.6 release notes, please submit the form.

New Measurements:

Stepped Sine Analysis – Measures high resolution frequency response functions under particularly challenging conditions such as when the system under test has enormous dynamic range, when system signal-to-noise ratios are poor, and in the presence of non-linearities.​​​​

New Features and Enhancements:

Update Channel Table Information in 900 Tests from Microsoft Excel – Load channel data from an Excel document directly into SignalCalc 900. Update input, output, and tach channel parameters in a 900 test from an external spreadsheet.

High Speed Shutdown (Soft Shutdown) Support – A safety feature that protects high-value test articles from damage during the testing process. It is ideal when used with Data Physics soft shutdown amplifier/shaker system.

Optimizations for Large Databases or many 900 Series Units Sharing a Data Server – Optimizations to ensure fast operation when test databases get large or when a database has tens/hundreds of thousands of runs.

Resume Random Vibration Test from any Stage – Resume a random test at any stage of the run schedule or a sine test at any frequency.

Faster Time History Recording Transfers when using Multiple Chassis – Improved the time taken to transfer a Time History Recording from multiple 900 Series Hardware units to the PC (Data Server).

Export Signals to ASCII Format Directly from Graphs

Frequency Points on Nyquist, Lissajous, and Polar Plots – Adds clarity while identifying and studying resonances.

Custom Color Maps in Waterfall Plots – Apply custom color schemes to your waterfall data to enhance data quality and to see patterns clearly.

Search Database for Specific Sensor and Shaker Serial Numbers – Search across all the tests in your database for a specific sensor serial number, shaker model, shaker name, or system serial number.

Show Clipped Channels Only on Channel Indicators – Narrows down and displays just the channels that need your attention.

…plus many more improvements!

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.
