Mixed Mode Vibration Control

Sine-on-Random and Random-on-Random Vibration Test Types

Mixed mode testing is used to simulate the vibration environment of structures where there is a combination of broadband and cyclic (narrowband) energy. Cyclic energy can be in the form of sweeping sine tones or narrowband random. For example, simulating helicopter vibration incorporates random vibration due to turbulence and sine vibration due to the rotor shaft and drivetrain.

Mixed Mode Vibration Control

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

Test 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

Streamlined Profile Entry and Manual Controls

View all parameters at a glance

Enter and view all Sine/Random components on a single page, without clicking through tedious menus.

Test Parameter Selection

Tests setup parameters are chosen automatically, or can be taken from an existing test.

Full Manual Control​

Manually increase test level before running the scheduled full level test

Manual control of Components

Manually turn any component on/off, set its sweep on/off, or change the overall level of the test at any time

Lab Integration and Test Safety

Thermal Chambers and More

Relay Card functionality allows easy communication with any thermal chamber or other Lab system (DP900-45)

Sequence Tests

Sequence tests to run automatically without operator intervention (DP900-48)

Full Lab Automation

Command the 900 Series Controller with your own software application or through relay signals for integration into an automated lab environment (DP900-43)

Physical Stop Switch

A physical stop switch is included with every controller

Shaker Limits Verification

Controller checks profile against shaker capabilities to ensure the shaker is not overdriven

Abort Triggering

High speed abort triggers from external safety systems plug directly into the hardware and quickly trigger a controlled shutdown
