ROSS ENGINEERING CORPORATION
These supply 120V or 240V AC continuous power for equipment that must operate while at a high voltage to ground or power source. For example, a fiber optic transmitter at the HV level for waveforms to be received and measured or recorded by grounded instrumentation might be powered by an isolation transformer secondary to primary either insulated by potting, oil or air. The low dielectric constant of air insulation provides lower capacitive coupling between the secondary and the primary or ground than would solid or oil insulation. The lower capacitance provides better isolation both at line frequency and especially at high frequency voltages such as lightning or switching transients.

LXinstruments GmbH
Manufacturers of electrical or electronic products are required by law to carry out an electrical safety test before placing them on the market. This final test takes place at the end of the manufacturing process and is therefore also referred to as an EOL test (end-of-line). Depending on the prescribed standard and directive, the following parameters are tested:- Leakage current and discharge current- Insulation resistance or the insulation strenth- Dielectric strength or electric strength- Correct installation of the protective conductor (ground continuity and ground bond test)- Faultless functioning of the product under the conditions defined for intended use (function or run test

ITS-9050 -
Innovative Technical Systems
The Innovative Technical Systems ITS-9050 Detector is a sensitive, harmonic mixing detector designed to measure millimeter-wave free-space radiation. It is ideal for measuring radiation patterns of antennas inboth the near and far-field. The ITS-9050 employs a free-running dielectric resonator oscillator (DRO) and an integrated harmonic mixer with a waveguide RF input that either connects directly to a circuit under test or to an antenna for radiation detection. The resulting IF is amplified and detected by an IF log-detector that drives a front panel LCD voltmeter to provide an indication of signal strength. A DC output voltage from the log detector is available on a BNC connector to drive external data acquisition instrumentation. Also, a sample of the IF output is provided for measurement on a spectrum analyzer.

Validyne Engineering
Featured are an integral variable reluctance transducer, solid state electronics module, 3 digit liquid crystal display (LCD)* and battery pack with six 1.5V penlight cells for truly portable operation. The units can also be powered from an external DC power supply or AC battery eliminator (converter) module. The transducer features all corrosion resistant materials in contact with the pressure media (both ports in differential units), very low internal cavity volumes and ultra-low volumetric displacement with full-scale pressure excursion. Transducer calibration is unaffected by dielectric properties of the sensed fluid. Gauge and differential transducers may be disassembled and range changed by simple diaphragm replacement.

ERAVANT
A lens antenna is a directional antenna that uses a shaped piece of microwave-transparent material to bend and focus microwaves by refraction, as an optical lens does for light.[1] Typically it consists of a small feed antenna such as a patch antenna or horn antenna which radiates radio waves, with a piece of dielectric or composite material in front which functions as a converging lens to collimate the radio waves into a beam.[2] Conversely, in a receiving antenna the lens focuses the incoming radio waves onto the feed antenna, which converts them to electric currents which are delivered to a radio receiver. They can also be fed by an array of feed antennas, called a focal plane array (FPA), to create more complicated radiation patterns.

Test Electronics
The most important features of the surge tester are its ability to test the entire winding insulation system. A high voltage surge generates turn to turn, coil to coil, and phase to phase voltage stress, as well as ground insulation stress. When used as a dielectric test, accurate voltage readings are essential. The HV Surge Tester monitors the voltage directly across the winding under test. This voltage is displayed on an oscilloscope and recorded on the Pass/ Fail LED latch monitor. This voltage will be accurate despite the impedance of the winding being tested. The insulation system can be tested way above the operating voltage because of the brief duration of the applied voltage test pulse. This allows faults to be detected long before they become apparent at operating conditions.

Fairview Microwave Inc.
Fairview Microwave’s semi-rigid test probe assemblies come in multiple cable diameters to help when attaching the unterminated end of the probe to a circuit board trace. There are two versions including straight-cut probe ends for those that would like to customize the dimensions of the center conductor and dielectric dimensions, as well as pre-stripped probe ends that are ready for immediate use. By soldering the outer conductor to the signal ground and the exposed center conductor to the trace carrying the signal of interest, simple sampling measurements can be made without having to create a separate subassembly circuit board or add a connector to the circuit layout which can take up valuable real estate. Fairview provides 3 diameters of semi-rigid coax and 3 different lengths from 3 inches to 12 inches to fit a variety of trace widths and applications. All test probes are 100% RF tested to ensure the cable assemblies operate to 6 GHz and also to make sure that the SMA connector interface meets the 1.35:1 VSWR specification prior to shipping. To protect the small diameter coax from damage, each part is shipped in a clear protective tube that can also be used for storing the probes for future use.
