Synchronous Accumulation (Order Analysis) -
ZETLAB Company
Order analysis is one of the most convenient and efficient methods for diagnostics and balancing of rotating mechanisms and transmission gears. With an RPM sensor and a vibration sensor, it is possible to study the time characteristics of gear vibration signals. It is a well-known fact that a signal from a vibration sensor is affected by signals from other sources. To tune out from the disturbing signals, the synchronous signal accumulation method is used. For each shaft rotation, the RPM sensor provides a rotation mark. This signal serves as a triggering strobe for the vibration sensor signal sweeping. The obtained signal sweeps are combined. All the sources of the signals related to the shaft frequency (frequency of rotation) are accumulated and increased in the accumulator linearly proportionally to the N number of rotations. All other signals that are not correlated with the shaft frequency are accumulated proportionally to N1/2 and in case of a greater number of averagings, the useful signal exceeds the interference level.

CKC Laboratories, Inc.
EMI is emitted radiation and its effects – a phenomenon. EMC is a device’s ability to limit the levels of unintentionally emitted EMI (that can harm other devices) and also a device’s ability to operate normally when subjected to EMI. Therefore, EMC testing seeks to ensure that a product possesses the characteristic of Electromagnetic Compatibility (EMC): the ability to limit creation of EMI (Electromagnetic interference) and the ability to operate properly when subjected to EMI. Stated differently, EMC testing measures the level of EMI control found in a device, and therefore helps to ensure that unwanted effects are prevented.

Com-Power Corporation
Com-Power broadband high gain preamplifiers were designed for electromagnetic interference (EMI) testing and certification. EMC test labs use preamplifiers to improve sensitivity of the test system during EMI radiated emissions measurements. Without a high gain preamplifier, signals picked by the antenna that have amplitudes below the noise floor of the test system cannot be measured. The preamplifier gain has minimum variations for the entire operating frequency range for accurate emissions measurements. The Com-Power preamplifiers were primarily intended for EMC applications. However, it can be used for other applications that require signal amplification.
