An Introduction To Direction Finding Methodologies
All direction finding methodologies are meant to determine the physical or geographical location of a source of radio frequency energy. The choice of an appropriate direction finding methodology to use for a given application is largely a function of the target signal's characteristics, such as frequency and modulation, but is also influenced by the propagation environment as well as cost and complexity. Recent advances in the development of hybrid direction finding methodologies attempt to overcome some of these restrictions and increase accuracy by using a combination of methodologies.
Battery Cycle Tool For The R&S NGU401/NGU201/NGM200/NGL200
The battery cycle tool has several charts that display collected data and can be used to characterize battery samples and create battery models.
Battery Simulation With DC Power Supplies
This application note guides users in creating custom battery models for R&S^®NGM200 and R&S^®NGU201 power supplies, enabling gradual battery discharge via QuickArb and data logging, with recorded data adaptable for battery simulation using a provided developer tool.
Linearity Of The JFET And MOSFET When In Saturation Over The Entire Cycle
Performing RF amplification in a way that is simultaneously linear and efficient has been a challenge in power amplifier (PA) design. Single transistor PAs can either be operated in a linear, but inefficient, current source mode of operation or as efficient, but nonlinear, switches. These techniques use two FETs, but this paper demonstrates that linear amplification can be achieved at high power with an efficiency greater than 60%, using a single FET.
Radiated Wireless Coexistence Testing
This application notegives the reader a clear idea of how to configure standardized test instruments from R&S in order to generate the wanted signal as well as unintended interference signals and conduct measurement to monitor device performance.
