PXI Express 24-Bit, Arbitrary Waveform Generator With Dual Channel Counter Input Designed For Precision Test Application

VTI Instruments is pleased to announce the introduction of its EMX-1434 - a PXI Express 4-Channel 24-bit 204 Ksa/s Arbitrary Waveform Generator with dual-channel 1 MHz counter/timers and digital I/O. Building on the company's pedigree as a leading precision modular instrument supplier, the EMX-1434 provides unmatched hardware performance for low frequency, high- accuracy applications, such as Engine Control Unit (ECU), Sound and Vibration or medical device functional testing.

Measurement accuracy is further maximized utilizing a unique approach for run-time self-calibration eliminating the need to disconnect field connections or remove the instrument from service. Complete end-to-end self-calibration is performed using a precise onboard voltage reference source permitting execution at test time, at current temperature. This approach not only delivers the most accurate measurements possible, but also validates the instrumentation signal path prior to test, resulting in maximum test equipment utilization, reduced need for spares, and reduced down time.

The EMX-1434 is a multi-function

• 4-Channel, 204.8 kSa/s/channel, 24-Bit DACs
• -115 dB spurious free dynamic range
• Integrated 2-Channel 64-bit tachometer
• Integrated 4-Channel DIO for synchronizing with dynamic signal analyzers
• Ideal for rotational measurement, and stimulus-response applications such as vibration test
• Output modes including Sine, Burst Sine, Chirp, Burst-random and continuous random

"The EMX-1434 has the power and performance of a standalone instrument but on a PXI Express card. With "lean" instrument drivers it can be easily integrated within our users application programs whether written in LabVIEW, C or other languages. Alternatively for mechanical test applications VTI's powerful DSA driver and software packages like EXLab, IDEAS for Test, X-modal tightly synchronize the instrument with VTIs digitizers to form a complete turn-key solution for NVH" commented Chris Gibson, Product Manager - Data Acquisition & Control.
