One of the key aspects of a hydronic mechanical system is the pump. If the pump isn’t designed or selected correctly, the entire system will not function. Using general principles and rules of thumb ...

Three tools are typically used to measure vibrational noise (noise) - a storage Oscilloscope (scope); a vibration sensor (sensor), which is generally a 'seismic grade' accelerometer 1; and a ...

Some brief theory and typical measurements of phase noise. How to produce the lowest phase noise at a PLL output. A standard design procedure for a typical Type 2, second-order loop. As stated in ...

The phenomenon of curve squeal noise in railway systems is a critical issue in urban rail transport, affecting both commuter comfort and community acceptance. This tonal high-frequency noise, ...

NTi Audio says a firmware update to its XL2 Analyzer offers on-site measurement of commonly used noise curves according to ANSI and ISO standards. The curves are visualized and presented with the ...

Factoring confidence and accuracy into the measurements for wireless systems can be somewhat complicated. By spending some time before running the test and doing some analysis afterward, the test ...
