LynxTM Software Modules and Test applications:
Sine Module
Spectral Dynamics software modules always provide you with the best in control technology. Our LynxTM Sine Module incorporates a true analog-quality sine sweep with a double precision integrated phase algorithm in order to ensure the lowest signal distortion possible. Our easy-to-use flexible user interface, will allow you to configure your control parameters: manual or automatic test, control with the fundamental signal (tracking filter) or with the RMS of the broadband, control strategy. Other Sine based software modules; Stepped Sine and Search& Dwell can be easily incorporated into your testing control suite with your original system configuration or added later to your system as your testing needs to expand down the road.
Random Module
Spectral Dynamics developed a control algorithm with separate controls loops dedicated to controlling the shape of the drive spectrum and overall RMS level. This optimizes the random control signal while providing both control speed and stability during your test. This “forward looking” technology allows the LynxTM to adjust the control speed in real time to the next measure of error that is about to occur. This control algorithm is one feature of our Adaptive Technology which ensures the control and repeatability you demand when testing to higher tolerance random control spectra while exciting your test product to give you the test confidence you need.
Shock Module
The LynxTM Shock Module solution generates different types of shock pulses to simulate the test item experiences in its real environment. As an expert in the field, Spectral Dynamics developed algorithms for shock testing with transfer function updating and coherence smoothing to accurately and quickly compensate for non-linearity or time varying changes which may occur with a dynamic load. The control strategy is easily defined by the user with pulse compensation, tolerances, number of control channels. SRS testing, automation of the shock test and repetitive pulse mode are available with our solution. The LynxTM stands alone in the industry as the “true tool” in realistic shock environment simulation.
Sine on Random Module
This application consists in combining pure sinusoidal signals with random signal waveforms. The highest quality random signals are generated and controlled via our advanced algorithm signal generation. The sinusoidal signals are then combined with the random waveforms and a high-quality spectrum is generated which can be then swept across your desired band of interest.
Random on Random Module
Random on Random simulates complex narrowband random on broadband random vibration environments. Narrow-bands may be swept or stationary. This vibration environment is typically seen in reciprocating equipment, repetitive impacts from tracked vehicles, and aircraft gunfire vibration.
Road simulation (Time replication) Module
Road Simulation application makes it possible to reproduce actual measured time history vibration data in the laboratory on your vibration system.
Signal Analyzer Module
The analyzer provides a comprehensive set of tools for data acquisition and signal analysis. Tests can be performed with or without output generation.
Options available for LynxTM software
Spectral Dynamics offers specific options to help you to increase the efficiency of the testing process from the definition to the report.
- Stream to disk: Time record and storage
- Remote control features: ActiveX or RCI
- Test schedule and Mission simulation: linking of multiple profiles
- And much more.

Our technology protects your test article and the test system while allowing for the ultimate in response delivering you the confidence in test results you desire.
Accuracy
The JaguarTM is the only system in the world capable of changing the input ranges during a test with no adverse effects on the data. This occurs in our Sine or Random applications ensuring optimal use of the available dynamic range.
MIMO Capabilities
MIMO (Multiple Input – Multiple Output)
The JaguarTM has the power to recreate multiple degree of freedom environments in your test laboratory. Applications as diverse as vibrating a complex configuration of electronics in 3 axes simultaneously, driving a very heavy structure in one axis while sharing the load over many shakers or even recreating 6 DOF movement at each of the four wheels of an automobile may now be accomplished with the Jaguar™ MIMO application.
The Jaguar™, well known throughout the world for advanced vibration controller testing, also has a strong application success for acoustic control technology. The Jaguar™ is unmatched in its ability to control and analyze advanced test configurations when performing Direct Field Acoustic Testing (DFAT) for Satellites. Contact local Spectral Dynamics sales representative to find out more about our DFAT capabilities and experience as well as see the detail below MIMO Random acoustic Module.
The JaguarTM solution provides a complete software suite for all your applications.
MISO Control software (Multiple Input Single Output)
Tests configurations with multiple input and requiring only one output drive, can be configured easily with the Jaguar™.
Sine Module
The main analysis of the test consists in using tracking filter to bandpass the desired data, synchronizing the center frequency of the bandpass filter and locking it to the drive frequency. Our team is proud to provide one of the best tracking filters with the JaguarTM solution.
Random Module
The purpose of random excitation is to expose the test article to all frequencies, all phases, and all amplitudes in a truly random nature. The only condition to this is the customers shape must be produced and maintained, without losing the true random nature of the energy.
Shock
The JaguarTM uses patented adaptive control algorithm with transfer function updating and coherence smoothing to accurately and quickly compensate for non-linearities or time-varying changes in the dynamic load.
Mixed mode (Sine on Random / Random on Random / Sine & Random-on-Random)
The mixed mode consists in combining broadband, narrow band and tones to perform vibration tests.
MIMO Control software (Multiple Input Multiple Output)
As a majority of vibration testing is performed with single shaker excitation systems, conditions often exist where single excitation is not appropriate to achieve the desired test control and results. For these applications, Spectral Dynamics has developed a MIMO applications software suite to simulate the “real world” and allow a multiple channel input while allowing for multiple output drive generation.
MIMO Random Module
MIMO Random provide digital real-time closed loop shaker control for production testing, design qualification, and reliability testing applications. The system allows the definition, simulation, and closed loop control of random vibration excitation of a system with multiple exciters.
MIMO Sine Module
During manufacturing and use, all products encounter stress. MIMO sine tests are performed on both prototype and production-line products to ensure that the product will survive actual production and in-use conditions. MIMO sine vibration environments generally consist of a single sine wave frequency that changes frequency over time at several driving (excitation) points.
MIMO Shock Module
Do you have a need for closed loop control shock testing with multiple vibration actuators? Our MIMO Shock application is the solution.
MIMO Replication Module
This application allows the replication of field measured time history vibration data. Real vibration environment can be played back and controlled on the test system in a laboratory environment.
MIMO Random acoustic Module
Closed-loop acoustic tests are typically performed on products to ensure that the product will survive actual in-use conditions. Random acoustic environments are characteristically non-repetitive in time, the energy is generally present at all frequencies over a frequency range. This acoustic environment can accurately simulate many real-world operating conditions.
The JaguarTM can generate a wide range of random acoustic environments to satisfy nearly any commercial, industrial, or military test requirement. For instance, Direct Field Acoustic Testing (DFAT) for satellites can be performed thanks to the Spectral Dynamics’ MIMO random acoustic application.
