Tuned half-wave dipoles have been among the most important antennas from thebeginning of rf-technique. The characteristics of half-wave dipoles havebeen calculable very early using the Maxwell and Hertz equations. Therefore the halfwave dipole became a reference antenna. The ideal (lossless) half-wave dipole has anisotropic gain of 2.15 dBi and an impedance of 73 Ohm. The directional pattern is circular inthe H-plane, "8-shaped" in the E-plane with the maxima perpendicular on the dipole axis.The half-power beamwidth (-3 dB) is approx. 78°. The impedance of real dipoles isdepending on the thickness/length ratio of its elements, typical values are 60-70 Ohm.Dipoles for industrial applications are available in the frequency range from 30MHz to up to approx. 4 GHz. The dipole elements are length variable (telescopic) orwith fixed length, the latter especially above 1 GHz. The most important applications aretest site evaluations (NSA, normalized site attenuation) and the determination of ERP(Effective Radiated Power) respectively EIRP (Effective Isotropic Radiated Power).

Analog Devices Inc.
The RS-485 specification meets the requirements for a truly multipoint communications network, and the standard specifies up to 32 drivers and 32 receivers on a single (2-wire) bus. Some RS-485 transceivers modify the input impedance to allow up to 8× more nodes to be connected to the same bus. Analog Devices offers a wide range of standard RS-485/RS-422 transceivers and iCoupler® isolated RS-485/RS-422 transceivers to suit many applications.

McLennan Sound Monitoring, Inc
The remote noise sensor assembly consists of a noise sensor mounted in a laser-cut, powder painted, 16-gauge metal chassis. The noise sensor assembly is connected to the main instrument with a four conductor cables and has an “on” indicator LED. Due to the power-balanced low impedance return signal, the remote noise sensor can be placed up to 1000 feet away from the McLennan sound level monitor main instrument without significant change in the signal.

12962A -
Ametek Scientific Instruments
The 12962A sample holder is designed to allow accurate impedance tests of solid materials to be performed at room temperature. The sample holder consists of two parallel electrodes, one of which is fixed in position and the other which can be moved into contact with the sample by adjustment of a micrometer. The sample holder makes use of guard ring and reference techniques in order to improve accuracy by reducing “fringing” effects at the edge of the sample. The standard electrode provided is 20mm diameter.

S96029B -
Keysight Technologies
This software application enables high-accuracy noise figure and noise-power measurements of amplifiers. It utilizes Keysight’s unique vector-source-correction technique, which uses a source-impedance tuner to remove the effects of imperfect system-source match. This approach yields accuracy that surpasses that provided by the Y-factor method and other cold-source implementations, especially for in-fixture, on-wafer, and automated-test environments. A scalar-calibrated method is also available that offers less accuracy but is faster and does not require an impedance tuner.
