Sport Sensor Range
-
DHE (Differential Hall Effect) sensors give an output when subjected to a changing magnetic field. The field is set up by a magnet inside the sensor body and changes when ferromagnetic teeth are passed beneath the sensor (no magnets are required in the target). To improve noise resistance, the sensor has two Hall effect elements and only responds to changes in magnetic field strength corresponding to tooth passing frequencies above 15Hz. As each tooth passes the sensor, the digital state of the output changes

Acoustic Analysis
-
Noise is increasingly the subject of new regulations for the protection of human health and safety as well as for improving the environment in general. As well as sound levels, the perceived sound quality of products from washing machines to vehicles is often an important part of the customer buying decision so must be considered during product development. m+p Analyzer for noise and vibration measurement and analysis provides a full range of capability for these applications. Real-time fractional octave filters satisfy all acoustic applications from simple sound pressure, sound power for equipment legislative requirements, intensity mapping to isolate sources to sound quality metrics for product refinement.

Noise Source, 1 GHz up to 40 GHz
346CK40
-
The Keysight 346CK40 is the ideal companion to Keysight´s noise figure solutions when working on high frequency applications. Since it is broadband (1 GHz to 40 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source greatly reduces measurement uncertainty, which are commonly reflections of the test signals. This is a coaxial noise source with a 2.4 mm coaxial connector. ENR typically 14 dB at 1 GHz, decreasing to 5 dB at 40 GHz (typical).
