Low-frequency vibration sensors, operating typically below 10 Hz, are critical in seismology, structural health monitoring and aerospace navigation. Accurate calibration of these devices ensures ...
An accurate way to calibrate a frequency source is to use a high-resolution counter/timer to measure the beat frequency, or phase difference, between the source to be calibrated and a reference such ...
As commercial, military/aerospace, and other communications designs extend into the millimeter wave (mmWave) spectrum, engineers must adapt their testing procedures and require more from instruments ...
The key to accurate readings is calibration, says OSHA, and the agency notes the International Safety Equipment Association (ISEA) recommends, at a minimum, verification of sensor accuracy before each ...
