There is a growing requirement for determining the location of emitters in radiomonitoring, security services, military intelligence, etc. Spectral components used in spread-spectrum techniques can only be allocated to a specific emitter if the direction is known. Direction finding is therefore an indispensable first step in radiodetection.
This white paper describes the basic functionality of antennas. Starting with Hertz's Antenna model followed by a short introduction to the fundamentals of wave propagation, the important general characteristics of an antenna and its associated parameters are explained.
The new R&S RT-ZVC02/04 multichannel power probe can measure across large current and voltage ranges without having to switch ranges, making it possible to monitor the power consumption of chipsets, radio modules and wearables such as smartwatches. When used in combination with an R&S RTE or R&S RTO oscilloscope, the current drain can be clearly correlated with analog and digital control signals, enabling developers to optimize the battery life of such wearables and wireless devices early in the development cycle.
The R&S RTO2000 model with 6 GHz bandwidth allows developers to test the radio interfaces of 802.11ac WLAN components for IoT modules in the 5 GHz band as well as fast communications interfaces such as USB 3.1 Gen 1 with data rates of 5 Gbit/s. Thanks to its multi-domain functionality, only a single compact instrument is needed to analyze power supplies, processors and sensors with up to 6 GHz bandwidth.
The new R&S RT-ZP1X passive 1:1 probe from Rohde & Schwarz broadens the application range of its R&S RTO and R&S RTE series oscilloscopes. Both the probe and the oscilloscopes' front-end are extremely low noise, making this combination ideal for measuring the smallest of signals down to 1 mV/div, e.g., for power integrity measurements on integrated circuits and components.
The electronica trade fair will be held November 8-11, 2016, in Munich. Rohde & Schwarz will present its portfolio of T&M solutions tailored to the requirements of today's most significant technology trends (hall A1, booth 307).
Rohde & Schwarz follows the call to London to attend European Microwave Week, where the company will demonstrate its T&M highlights for demanding applications in the aerospace & defense, automotive and wireless industries. In focus: test solutions for satellite communications, for radar applications in the A&D and automotive sectors and for the next generation of mobile networks 5G.
Rohde & Schwarz has enhanced its proven test solution platforms to include advanced capabilities that are facilitating the research, development and standardization of 5G. The fifth generation of mobile radio will open up new frequency bands for commercial wireless communications in the microwave and millimeter wave ranges to increase date rates on a massive scale.
The new R&S RTO-K44 option from Rohde & Schwarz offers powerful triggering and decoding functionality for debugging designs with MIPI M-PHY based protocols. Defined as a physical layer, M-PHY serves as the basis for a number of protocol standards that have been optimized for rapid data transmission in mobile devices.
