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.
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.
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.
20 Channel Digital Delay Generator with 5 Picosecond Jitter: Model 745-20C-T
As its model number implies, the 745-20C-T is a digital delay generator with 20 channels in one unit. It features a 100 ps time resolution (standard, with an optional 250 fs time resolution), 5 ps jitter (internal trigger), a 25 ps jitter (external trigger), 1 ns output rise times, and more.
Varactor Tuned Navigation Band Preselector: TF0112
MtronPTI’s TF0112 varactor tuned aviation navigation band preselector improves safety in cross country and landing operations by attenuating interfering signals that might cause a cockpit radio to lose lock on a desired VOR or localizer/glide-slope signal.
Test, Control, And Verify: New Location, Better Solutions
Corry Micronics recently moved to a new facility in accordance with their new product development initiatives, particularly in the microwave space. RF Globalnet recently made the trip to check out the new digs and to catch up with Don Pavlek, president and CEO, and Jim Price, vice president of engineering.
Modeling Material Properties Based On Measurement
This webinar video presents how to use CST STUDIO SUITE® for a number of techniques for extracting material properties based on the measured S-parameters of simple geometry samples. The video will also discuss the importance of manufacturing technology in the extraction process in relation to the robustness of the specific technique. Important effects such as etch factor, over-etching, over-milling, metallization thickness, and the connection repeatability of low-cost end-launchers will also be addressed in real-world examples.
How Wireless Works
This is a short, animated video explaining what happens each time someone uses smartphones, tablets or other wireless devices.
Attenuation Made Easy
Bryan Walker with JFW closed out our IMS 2015 coverage with a short and sweet demo of the ease-of-use of their 50P2014 SMA attenuator.
Switch, Amplify, Split, Route
Dominic Overton and Dr. Esen Bayar took a few minutes out of day three of IMS in 2015 to familiarize us with their wide range of offerings. Watch the video for an overview of solutions designed for telecoms operators, global satellite operators, and the government and military sector.
