VXI Switching
-
The Aerospace and Defense industries were early adopters of modular test platforms. One of the first successes was VXI test systems and VXI switching. They served these industries very well for more than 20 years. Now, as VXI test systems become obsolete, test systems developers are looking to PXI as the next generation modular test platform for their industries. We offer a few different references to help you in making a switch to PXI.

Sound Level Calibrator
511E
-
Accepted internationally 1 kHz represents the "0 dB" reference point of A, B, C Weighting and other filters utilized in acoustic measurement. The Pistonphone - a mechanical sound source - offers a slightly higher degree of accuracy at a substantial increase in cost. In addition, the 200 or 250 Hz operating frequency is mechanically limited and not suited for measurements of filtered inputs. The 0.2 dB accuracy is quickly lost in the 0.7 to 1.5 dB tolerances acceptable for weighting filters at frequencies around 250 Hz.

Ultrasonic Sensing
-
Ultrasonic sensing is the measurement of the time between an ultrasonic signal being sent and received. The interval between these two signals is typically referred to as time-of-flight (ToF) and depends on the distance the ultrasonic wave travels until it is reflected due to an impedance change and the speed of the ultrasonic wave. The basic equation time = distance / speed can be used to measure fluid level, fluid identification/concentration, flow, or proximity.
