Select the Import tab on the Random Test Settings dialog box.
From there, you can automatically generate a spectrum profile from input data. The input can be a set of frequency/amplitude breakpoints or a time/acceleration history stored in a text file.
To input data from a file, perform the following procedure:
- Select the input method from the drop-down list.
- Select the input file button and choose a file. The software will scan the file, and the dialog box will update to reflect the contents of the file.
- Set the sampling rate, header lines, and column number for the acceleration data, and the acceleration units used in the file.
- Select the spectrum generation method. The import procedure will divide the file into 1,024 sample blocks, compute the spectrum for each block, and then combine the blocks according to the selected method. Average will average all the spectra using a uniform average. Peak hold will extract the peak values over all the blocks at each frequency.
- Select the Create Table button to process the file and create the frequency/amplitude breakpoint table from the input file.

How can I view a controller's dynamic range?
The importance of a vibration controller’s dynamic range is often misunderstood. A controller may specify the input or output dynamic range or the overall range.
Rather than referencing the specifications, you can run a test with the controller to view the total system dynamic range. To run the test, create a random profile with a section of the profile reduced to nothing. You can determine the random dynamic range by observing the actual level of the profile.
The Chinese government uses test specification JJG 529-88 to specify a system’s dynamic range. The engineer can run the test on a shaker system or on the controller “looped on itself.” The test has the following breakpoints:
|20 Hz||-40 dB|
|80 Hz||0 dB|
|300 Hz||0 dB|
|350 Hz||-40 dB|
|350 Hz – 500 Hz||no energy|
|500 Hz||-40 dB|
|600 Hz||-20 dB|
|650 Hz||-20 dB|
|700 Hz||0 dB|
|750 Hz||-20 dB|
|800 Hz||-20 dB|
|1000 Hz||0 dB|
|1500 Hz||0 dB|
|2000 Hz||-20 dB|
The VR9500 demonstrated a dynamic range of 90+dB with JJG 529-88. Many controllers that claim 80dB of dynamic range show only 50dB or 60dB with these specifications. Lack of adequate dynamic range may cause system problems when controlling a fixture with a large resonance.
The figure below displays a more detailed explanation of the dynamic range.
For a more detailed explanation, please click here.
Is my controller working properly?
Sometimes a vibration testing system is generating errors or is not operating at all, but the cause isn’t clear. It could be a loose connection, frayed cables, issues with the amplifier, a malfunctioning shaker, or, in rare cases, a problem with the controller itself. Loopback Diagnostics is a straightforward way to determine if your controller is working properly.
Loopback Diagnostics is a VibrationVIEW tool that allows the user to verify the functionality of a VR9500/VR10500 controller. It internally connects the Drive or Cola to the input channels (usually during a System Check test), which eliminates the need for BNC cables or running a shaker.
CAUTION: The Drive and Cola outputs remain active in Loopback mode. By looping the Drive back to the control channels, you are running the controller open-loop (the control channel is disconnected from any accelerometer connected to the input channels). Make sure to disable your shaker or disconnect the drive cable to prevent shaker movement.
CAUTION: Channels connected in Loopback mode must be disconnected from any accelerometers or input sensors. Any channel limits defined in the System Check Test Profile will be enforced on the Loopback signal, not the actual input signal.
For detailed instructions on setting up and running Loopback Diagnostics, see the video below:
If the input channels are displaying accurate voltages, then the problem is in one of the other components and not the VR9500/VR10500.
Where can I get an electronic copy of the manuals?
There are several manuals that coincide with our hardware and software:
- VibrationVIEW operation manual
- ObserVIEW operation manual
- VibrationVIEW Quick Start Guide
- ObserVR1000 Quick Start Guide
- Hardware manuals (VR9500, VR10500, and ObserVR1000)
All manuals are located on the software CD in the Manuals directory in a Word (.doc) or PDF format. The Word version requires Microsoft Word or the MS Word Viewer. The PDF version requires the Adobe Acrobat Reader.
The manuals relevant to VibrationVIEW/ObserVIEW can be accessed in the Help file of the software.
The manuals can also be manually downloaded here.
Why is the emergency stop button an important safety feature?
The emergency stop (e-stop) button provides further safety measures for lab personnel, testing equipment, and products under test. It gives lab personnel a quick option to stop a test without putting a transient shock into the test product.
How do I install an emergency stop button?
If you selected the optional e-stop button for your controller:
- Plug the Phoenix connector to the back of the I/O unit.
- In VibrationVIEW, select to Configuration > Remote Inputs.
- Point to the eighth drop-down box and select “Emergency Stop Button.” Select the OK button.
How often should I calibrate my VR hardware?
We strongly recommend an annual calibration. The system arrives factory calibrated, so you do not need to calibrate it again until the due date on the calibration certificate.
What are my options for calibration?
There are three calibration options for the VR hardware:
- Send the hardware to Vibration Research for calibration.
- Calibrate the hardware yourself with VR Software.
- Perform the calibration yourself.
Please see our calibration page to read more about these options.
My accelerometers require a recalibration: what do you suggest?
VR’s accelerometer calibration performs automatic and accurate calibration and verification of IEPE accelerometers and charge-mode piezoelectric accelerometers/transducers in your lab.
Otherwise, we suggest that you send your accelerometers directly to the manufacturer for recalibration. If you purchased your accelerometer directly from VR and are not sure who the manufacturer is, contact us for more information.
I am experiencing trouble with calibration verification in my lab. What could be the issue?
Performing calibration verification in your lab can save time and money, but sometimes the process stops and it is not clear why.
Problems usually arise at one of two steps:
- If the Next > button is unavailable after selecting the device and configuration, then the analog connections (output to channel inputs) are not functioning and the verification process cannot move forward (see image below).
Check the cables and the connectors, as some components may be worn or frayed and have stopped functioning.
- VibrationVIEW populates the Certificate Entry form with the appropriate data, including the type of digital multimeter (DMM). If the DMM is not connected properly, or if it is an unsupported DMM, then VibrationVIEW will not populate the form with the DMM information (see image below). The procedure may continue but will stop intermittently or fail because the appropriate connection between the DMM and the PC has not been established.
The most common DMM connection problem is due to a USB to serial adapter that isn’t fast enough to keep up with VibrationVIEW transmission speeds. Vibration Research recommends a B+B Smartworx USB to serial adapter (part number: 232USB9M). If you have a PC with a serial port, you may connect to the DMM directly with a null-modem cable instead.
If you are still experiencing trouble with the calibration verification procedure, please contact us.
What shakers can I control with my Vibration Research controller?
Vibration Research systems can control all electrodynamic and servo-hydraulic shakers.
How do I determine the correct shaker size?
The industry uses the equation Force = Mass x Acceleration as the basis for sizing shakers and determining if a shaker can perform a shock or vibration test. All shakers have a force rating that determines what combination of mass and acceleration the shaker can achieve.
To perform a quick F=MA calculation, visit our Calculations page.
What is total harmonic distortion?
Total harmonic distortion (THD) is the summation of the amplitudes of various harmonics when a pure sine tone is inputted into a system. THD not only measures the quality of a sine wave but can determine how well a system is replicating the signal from the controller. Small values indicate the system is performing as requested. In the physical test environment, a high value suggests a weakness or malfunction of the shaker system.
THD can be used to measure the accuracy of a vibration system and help to track system changes over time. You can buy harmonic distortion analyzers to perform the measurement for you or use equipment you already have in your laboratory: a vibration controller/analyzer.
How can I measure the THD of my shaker with my vibration controller?
You can measure THD by exciting your system with a sine wave, reading the g2/Hz displayed by the system, and noting the difference in dB between the fundamental frequency and higher-order harmonics. The harmonics occur at 2x, 3x, 4x, etc. of the fundamental frequency. As most controllers read directly in g2/Hz, a change in 10x g2/Hz is a 10dB change. For example, 0.1 g2/Hz to 0.01 g2/Hz represents a 10dB change.
Remember: dB = 20 log (A/B). Thus, a 10% distortion (0.1 ratio) will appear as -20 dB.
-20dB = 20 log (0.1)
The following is an example of harmonic distortion from a sine wave generator. The generator was set to 100Hz. The third harmonic is the highest spike at 40dB (4 major divisions) down from the 100Hz fundamental. This test reports the third harmonic distortion at 1%, which matches the specification for this waveform generator. Also, 40dB correlates to 1% on the table.
|Change in dB||Change in %||Change in dB||Change in %||Change in dB||Change in %|
What happens if I lose power to my computer, controller, and shaker amplifier?
The more recent versions of VibrationVIEW store data in a Temp folder even if “Save data to disk” is not selected on the Data tab in the test settings. The auto-saved Temp file is saved at the time interval set on the Data tab, even if the checkbox is not selected.
To retrieve the saved data, navigate to the Temp directory and select the last saved data file, which is named with a time-stamp. The default is C:\Users\username\AppData\Local\Temp (How to show hidden files, folders, and drives in Windows 10/11).
Refer to the time history or print a report to determine how long the test ran. This information will give you a starting point to continue with the test. You may have to reset your amplifier prior to restarting the test.
What happens if I lose power to my shaker and controller but have UPS backup on my PC?
After the test stop code message “Lost Contact with IO box s/n” appears, you can resume the test as long as power is restored to the amplifier and controller. Otherwise, the data can be manually saved by selecting the Save Data button.
You can also retrieve the data by navigating to the Temp directory and selecting the last saved data file, which is named with a time-stamp. The default is C:\Users\username\AppData\Local\Temp (How to show hidden files, folders, and drives in Windows 10/11).
If you have data set to automatically save at the end of the test, then all information will be saved up to the time that a communication error occurs. You may have to reset your amplifier prior to restarting the test.
What happens if the accelerometer cable breaks while a test is running?
The controller will gently stop the test to prevent transients from passing through your shaker. A stop code with a message similar to “Max acceleration on Ch X” will appear.
