Sine Data Reduction
Monitor Hundreds or Thousands of Channels in a Sine Vibration Control Test and Configure Abort Channel Profiles to Trigger the Controller to Abort
SignalCalc Sine Data Reduction is used during a swept sine test under the direction of a vibration controller, providing additional measurement channels to supplement the controller. Sine Data Reduction also serves as a critical safety system for protection of high value test articles like satellites, triggering the controller to stop within milliseconds of a pre-defined tolerance being exceeded.
The powerful analysis functions and easily customizable graphical user interface features facilitate data analysis and comparison with analytical models, enabling test engineers to make critical decisions when testing high value test articles.
Proven Sine Measurement Capabilties
Programmable Tracking Filter
User specified, high quality fixed or proportional frequency bandwidth tracking filters.
Transient Monitoring
Monitor gap-free for transient events on any channel, and trigger the vibration controller to abort if any occur.
Channel Averaging
Multiple channels may be averaged (average, RMS average, Maximum, Minimum) to calculate the average control used by the vibration controller.
User-Defined Alarm and Abort Profiles
Alarm and abort profiles provide additional safety for high value test articles by providing warnings and remotely aborting the vibration controller test.
Safe Shutdown
Trigger the vibration controller to abort the test with an ultra-low latency trigger – a critical part of a Soft Shutdown test system.
User-Specified Sine Measurement Processing
User specified Average, Peak, RMS, Tracking Filter, or DC amplitude measurement.
Advanced Test Capabilities
Channel and Signal Math (DP930-80)
Gap-free math operations may be applied on live data to compute summed forces/moments for force and moment limiting; or to calculate velocities or displacements.
High Channel Count
All signal processing is performed on the DSP cards themselves, allowing the system to expand to hundreds or thousands of channels
Simultaneous Multiple Measurements
Run a secondary measurement simultaneously with the Sine Reduction test to speed up data analysis. Eg. visualize harmonic excitation on a waterfall plot – generated live during the sine sweep with no post processing required.
Time Data Recording (DP930-23)
Raw time data may be recorded at up to 216 kSamples per second
Comprehensive Sine Data Reduction Features
1 Control Signals
Average control signals can be computed and overlaid on tolerances (reference, alarm, abort).
2 Abort Profiles
Abort profiles, used to protect test articles, can be displayed in graphs during testing.
3 Transmissibility
The transmissibility between any two channels can be computed, saved, and displayed during testing.
4 Time Data
Both sweep data and time data can be displayed during testing.
