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.
High Power Microwave Signal Generator: Model 845-HP
Higher power in their signal generators was Berkeley Nucelonics’ number one request from their customers, and they delivered on it. The model 845-HP microwave signal generator is very similar to the model 845, but its wide and accurately levelled output power range (up to +23 DBM) and high spurious suppression set it apart.

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.
