Are You Using The Best Oscilloscope For That Application?

The quality that makes oscilloscopes invaluable in any electronic laboratory is their range of utility. While all oscilloscopes perform the same essential function and follow the same central principles, there are several specialized instruments used in various applications. In this article, we give you a bird’s-eye view of the different types of oscilloscopes, as well as some suggestions on their ideal usage.

ETL Systems In Action: Customized Solution Helps Arqiva Expand UK DAB Network

Arqiva, a UK based communications infrastructure and media services company, has been working on a number of projects to expand the UK nationwide DAB network. Since these projects demanded a smart and cost effective solution for distributing critical L-band satellite signals at multiple UK transmitting stations, Ariqiva chose ETL Systems to construct compact products to meet their requirements. This case study discusses how Arqiva relied on ETL Systems to help increase local DAB coverage so that millions of customers can receive their favorite radio stations digitally.

Selecting Microwave/RF Cable Assemblies For Reliable Performance Over Time

A study shows that more than 75 percent of microwave/RF cable assembly users replace their cable assemblies frequently. The only way to ensure reliability is to select a cable assembly that has been tested to survive in real-world conditions. This white paper presents information on what kinds of cable assemblies are good for signal integrity, long-term durability and performance, and a lower lifetime cost.

Crossing Enemy Lines – The Growing Demand For Submersible Technology

This paper examines USSOCOM's emerging requirements for new and updated submersible equipment, with a focus on the factors that qualify such equipment for operation in combat environments. Specifically, it addresses the components most often considered the weakest link – namely, electrical cable connectors. Typically, significant changes in military equipment requirements such as this spawn innovation in the private sector. So the paper concludes by reviewing the types of equipment for which the 20-meter submersible capability may soon become standard.

Bird 8941 Series Oil Loads

The 8941-115SC13, 15 kW, Oil-Cooled Termination with 115 VAC Blower Assembly is a general purpose, 50 ohm, coaxial RF transmission line termination, useful as standby reject load or dummy load. It provides accurate, dependable, and low reflection line termination over a frequency range of dc – 20 MHz. Up to 15,000 watts can be dissipated. The loads have a coolant chamber surrounded by radiator fins. The front and rear fins form mounting flanges which can be used as supports for freestanding use or as brackets for fixed mounting. A vent plug at the top of the unit relieves internal pressure from coolant expansion and a blower assembly with three axial fans that line the bottom of the load.
