SRS Shock Control

SRS Shock Control is used to Simulate the Complex Vibration Environment Seen in Earthquakes and Pyrotechnic Shock

SRS Shock Control synthesizes a time history that conforms to the given SRS reference.  The SRS controller is the optimal controller choice for high frequency shock control, and has the ability to make independent SRS or Frequency domain measurements while the SRS controller is running – with SRS parameters independent of the controller SRS

SignalCalc 900 SRS Control

Streamlined SRS Setup Parameters

SRS Breakpoint Table

SRS shock breakpoints are entered in a table, or can be imported/pasted in from another application

Waveform Generation

Generate a waveform that conforms to the SRS reference, with a user-defined duration

Wavelet Types

Damped Sine, velocity/displacement compensated damped sine, Random, or Sine Beats wavelet types

Editable Wavelet Table

Wavelet table can be copied/pasted to/from other applications; and additional wavelets frequencies can be added

Minimize TE

Minimize TE algorithm can be applied when generating time waveform

SRS Max/Pos/Neg Display During Setup

Display the Max/Pos/Neg SRS reference while setting up the reference SRS pulse

Velocity or Displacement Computations

Math Channels (gap free) can be used to compute the velocity or acceleration of any accelerometer; or combined math across multiple accelerometers

Eliminate waveform offset

Apply a highpass filter to eliminate any offsets in the generated pulse

Features for the Power User

Use Your Own Damped Sine Table

The software allows you to forego generating the pulse from the SRS – and instead will allow you to enter your own SRS profile and wavelet table

Copy/Paste the Damped Sine Table

Copy and paste the damped sine table to/from Excel or other application to easily define your own custom SRS pulse

Time Domain and SRS Tolerances

Abort the test based on a time domain tolerance excursion from the reference waveform; or because of an excursion in the SRS of your control channel

Advanced SRS Control and Measurement

High Frequency SRS

Band limit the shaker drive to run an SRS test to a higher frequency than the shaker is capable of exciting

Secondary Measurements

Run secondary, independent SRS Measurements live during test, and recompute the SRS live during test with different parameters (min/max freq, 1/n octave, damping, etc) 

Manual Controls

Increase shock level manually before running the full test schedule. This helps ensure that control is optimized before running full level pulses

Stored Drive

Correction can be turned off once a desired drive signal is obtained (stored drive)

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

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

Create Custom Report Templates in 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

SRS Control and Analysis

1 Full Manual Control
Automatic or manual control of pulse polarity, level, control parameters, and number of pulses.

2 Recompute SRS Live
Change SRS parameters live between pulses during a test and recompute SRS signals – completely decoupled from the SRS Control


3 Recomputed SRS Display
Display the recomputed SRS in the same plots as  the reference SRS and abort tolerances

4 Live Control Display
Live, customizable plots that can be printed in reports
