10 Reasons Test Engineers Prefer Data Physics 900 Series Analyzer / Controller for High Channel Count Vibration Testing
01: Data Accuracy
If channels from different cards/chassis are not phase-synchronized, computations comparing measurements from different cards/chassis will be inaccurate. FRFs, Transmissibility, Math Channels, and more – all will be inaccurate.
The 900 Series delivers the industry’s most accurate data – made possible via our industry leading 0.025deg @ 2kHz (0.5deg @ 40kHz) phase-snychronization – of every sample – across every channel – even with multi-chassis configurations.
02: Channel Flexibility
Wish you could use any channel from any card/chassis as a control or limit channel in a vibration control test?
Competitive products don’t allow this. Critical channels are then restricted to the number of channels in the primary chassis, limiting the total number of channels in a given test.
With the 900 Series, you can measure, control, and limit on any channel, on any chassis. Math channels (summed forces/moments, relative displacement, etc.) can be computed across any channel/chassis, and can be used for control, limiting, or measurement.
03: Processing Speed
Still tolerating bottlenecks?
Other high channel count systems can have processing or data transfer bottlenecks – reducing the system performance when using lots of channels.
With the 900 Series, there are no limitations on sample rates, block sizes, analysis parameters, or control capability regardless of the number of channels or chassis.
04: Workflow Efficiency
Are you wasting time with post-processing?
Other systems limit recording and analysis capability to not exceed their bottleneck.
With the 900 Series, traditional “post-processing” can be performed live on any/all channels. Independently defined measurements are executed during a vibration control or another signal analysis measurement. These include:
- FFT Analysis
- Transfer Function Analysis
- Waterfall Analysis
- Time Recording, with Automatic Export
05: Sample Rate Flexibility
Are you confined to using the same sample rates on all channels?
Other systems impose restrictions on time data sample rate, or only allow one sample rate across all channels.
With the 900 Series, you can record multiple time history streams simultaneously at different sample rates and export the time histories to Matlab and other formats while the test is still in progress.
06: Power + Agility + Stability
Is your control or acquisition software unstable when you use hundreds of channels?
Other acquisition/control systems aren’t optimized for high channel count tests – and become unstable when configuring or running many channels.
The 900 Series’ software is designed and optimized for high channel counts. Menu’s update quickly, displays don’t lag, and the user interface remains responsive before, during, and after testing.
07: Easy to Set Up and Run
Is connecting and configuring multiple chassis to run together time-consuming? What about configuring sensor parameters on hundreds of channels?
Other systems take hours to connect and configure as a multi-chassis system, as they were primarily designed for single chassis use. Additionally, they don’t have tools to simplify entering channel names, sensitivities, and units. Configuring hundreds of channel parameters and plots one-by-one is unacceptable.
For 900 Series users, setting up multiple chassis to work together is as easy as checking a box and connecting the clock cable. Software manages all IP addresses and connections between chassis. Other ease-of-use features include:
- Configure channels programmatically, directly from Excel, or by copy/paste.
- Filter by metadata fields in every channel or signal selection menu.
- Simple plots/template setup, native multi-monitor support, and more.
08: Intelligent Licensing
Is Licensing a hassle when daisy-chaining chassis?
Other solutions have arcane software licensing processes, which require new licenses to be installed when combining systems.
With the 900 Series, software licenses are completely managed by the software, and the appropriate licenses are automatically selected when combining multiple chassis.
09: Test Data Security
Can your system continue running if the host PC stops?
Other systems are dependent on a dedicated PC per test setup, and the dedicated host PC is often a processing bottleneck.
If the host PC, analysis software, Windows, or the network connection crash during the test, your data can be irrecoverable.
With the 900 Series, all measurement processing and control is performed on the chassis. If the host PC disconnects, the test can be configured to either continue or ramp down safely.
10: Live Test Accessibility
Can multiple PCs view the test as it is running?
Other systems are often limited to a single PC to view live and post test data.
The 900 Series allows remote monitoring of live tests from any PC on the network. Remote monitoring enables independent access to all test data, and viewers can customize signal displays without impacting the execution of the live test.
About Data Physics
Data Physics, owned by Battery Ventures, was founded by two Alumni of Hewlett Packard in 1984. Dave Snyder had designed hardware and software for the Fourier Analyzers developed at the Santa Clara Division of HP. Sri Welaratna had worked for HP in England, Europe and then in Santa Clara developing applications of Fourier Analyzers. The first project Dave and Sri did together was the design of the UD 400AT vibration controller, the first to use a PC as the host computer and a DSP based signal processing peripheral. This project began in 1983 and used the Texas Instruments TMS32010, the very first Digital Signal Processor.
Starting with the SignalCalc software library for HP Basic computers Data Physics evolved to signal processing solutions on PCs using add on DSP hardware to provide the computational power required for realtime measurements and analysis.
In 2014, Battery Ventures bought a controlling stake in Data Physics. DP is the fifth active industrial-technology platform in the Battery portfolio. In 2015, Battery Ventures acquired a controlling stake in both Lansmont and Team Corporations, establishing the foundation of the Noise & Vibration Technologies (NVT) Group.
