OVERVIEW High Performance Architecture The EMX-1434 is an arbitrary source/tach high performance modular PXIe board which has four channels arbitrary sources and two channels tachometer inputs. It is uniquely designed for sound/ vibration and DSA applications and can be easily synchronized with digitized data giving the capability to combine the required source and signal analysis into one single chassis to maximize flexibility. It supports various output modes such as Sine, Burst Sine, Chirp, Burst-random and continuous random. It also provides two 64-bit tachometer/counter input channels...

Analog Performance Built-in Tachometer inputs for Rotating Machinery/Order Analysis Tests The EMX-1434 has integrated dual tachometer inputs with signal conditioning for a wide range of Tach input signals. These inputs allow tight integration of tachometer information from rotating machinery with acquired data from a digitizer card. This provides the information the floating point processor needs to do RPM triggering of order analysis measurements. Data accuracy can be increased by the fact that the measurement data can be re-sampled and synchronized based on the edge of the tachometer....

Analog Performance Built-in self calibration Measurement accuracy is maximized utilizing a unique approach for run-time self-calibration eliminating the need to disconnect transducers or field connections. 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. Complete embedded NIST traceable calibration eliminates the need to remove the instrument from...
