Keysight Technologies, Inc. is an American company that manufactures electronics test and measurement equipment and software. The name is a blend of key and insight. [2] [4] The company was formed as a spin-off of Agilent Technologies, which inherited and rebranded the test and measurement product lines developed and produced from the late 1960s to the turn of the millennium by Hewlett-Packard ...
An antenna designer must take into account the application for the antenna when determining the gain. High-gain antennas have the advantage of longer range and better signal quality, but must be aimed carefully in a particular direction. Low-gain antennas have shorter range, but the orientation of the antenna is inconsequential.
A reference antenna is an antenna with known performance. It is normally used to calibrate other systems. It is normally used to calibrate other systems. During a relative calibration, an antenna's phase center offset (PCO) and phase center variations (PCV) are computed with respect to the reference antenna which is normally assigned zero PCV ...

Several coaches are squarely on the NFL hot seat entering Week 18, with Mike McCarthy and Brian Daboll among those facing uncertain futures.
CISPR is the acronym of Comité International Spécial des Perturbations Radio, [1] or the International Special Committee for Radio Protection of IEC. CISPR Standards aim to the protection of radio reception in the range 9 kHz to 400 GHz from interference caused by operation of electrical or electronic appliances and systems in the electromagnetic environment.
The combination R-G-B = HH-HV-VV combines radar images of waves sent and received horizontally (HH), sent horizontally and received vertically (HV) and sent and received vertically (VV). The calibration of such instruments is done by imaging objects (calibration targets) whose radar brightness is known.
