 05.10.2012 VTI Instruments Corporation is pleased to introduce the EMX-4350 4-channel, 24-bit, 625 kSa/s smart digitizer module for the PXI Express platform. As the latest addition to VTI's sentinelEX series of PXI Express instruments, the EMX-4350 is one of the most advanced data acquisition modules available, delivering 625 kSa/s data rates simultaneously across all channels. The EMX-4350 has been optimally designed for high speed data acquisition, ground vehicle test (GVT), acoustic analysis, impact test, vibration analysis, order analysis and modal test applications.
The EMX-4350 provides granularity in 4 channel increments allowing for scalability and matching with any PXIe or PXI (in hybrid systems) modules in building a modular system to fit any application. Combining the EMX-4350 digitizer with the CMX09, 9 slot PXIe chassis allows for deterministic slot-to-slot communication and control with data bandwidth of up to 8GB/s. Maximum data rates can be achieved across all channels on fully loaded 9 slot and 18 slot chassis for up to 68 channels acquiring data simultaneously on one PXIe 3U rack mounted chassis.
Scalability from four channels to thousands of channels through the utilization of the IEEE-1588 standard gives users the flexibility to distribute the location of their acquisition instrumentation to maximize measurement accuracy. This industry standard allows measurement data to be synchronized to within 100ns across multiple chassis in different locations.
Best-in-class noise immunity and exclusive low frequency common mode trimming combine with the highest quality instrumentation grade 24-bit ADC's to deliver superior measurement fidelity (-125 dB SFDR). Cross channel phase matching to within ±0.01° delivers the uncompromised phase response required for accurate single and cross channel measurements common in most DSA and high-speed data acquisition applications. In addition to unmatched DC and AC transducer input performance, the complete measurement chain is further optimized with uncompromised excitation flexibility from 2 mA to 20 mA, designed to maximize transducer performance and response.
FPGA-based, 'smart' synthetic instrument customization extends traditional hardware performance by combining nearly unlimited user-defined computational, processing, and control possibilities to deliver unmatched measurement performance and flexibility. "For the first time our 'smart' line of PXIe digitizers gives our customers the power to access and customize the on-board FPGA to tailor signal filters and DSP algorithms to their specific requirements," said Tom Sarfi, VTI's VP of business development, "customers can now use industry-standard tools such as MATLAB® and Simulink® to graphically implement and reuse FPGA designs as well as pick from hundreds of signal conditioning filters and analysis algorithms."
Industry standard drivers and open application programming interfaces provide the flexibility and freedom of choice to customize or select the environment best suited to the specific development requirements. Alternatively, the EMX-4350 can be paired with a variety of turnkey software packages geared towards common applications for an intuitive, easy to use, data acquisition solution.
