(BVS) and EDX Wireless, leading providers of advanced wireless design and validation solutions to the domestic and international wireless telecommunications industry, have announced a collaboration to support each other‘s popular hardware (Coyote) and software (SignalPro) platforms. EDXSignalPro is the principal building block of EDX‘s comprehensive line of wireless network engineering tools. It offers all of the study types needed to design a wireless network, including area studies, link/point-to-point studies and route studies. The EDX family also includes Signal-IQ, a comprehensive software system for the design of in-building wireless networks, including Distributed Antenna Systems (DAS), picocell, femtocell and 802.11 Access Point (AP) deployments. EDX Signal-IQ is a fully integrated standalone indoor RF design tool focused on the unique and evolving needs of inbuilding design. Designed with simple operation, yet with accurate RF coverage predictions as its primary goals, Signal-IQ streamlines end to end design of in building RF networks of all types Coyote is a high performance, modular receiver system providing two unique and independent RSSI measurements using precision dual receivers. Coyote supports hot-swappable components including removable/rechargeable Li- Ion battery, CF storage cards, removable 12-channel GPS receiver module and two removable calibrated receiver modules for both indoor and outdoor drive-studies. ■ Berkeley Varitronics Systems www.bvsystems.com 48 hf-praxis 8/2012
RF & Wireless Test & Measurement Agilent Technologies Enhances FieldFox RF Analyzers with Options for Measuring Time Domains and Channel Power measurements, reducing errors caused by out-of-band signals. A large display, simple settings, and a price tag that‘s less than buying an external USB sensor make the channel power-meter option easy to use and ideal for today‘s cost-sensitive customers. The Agilent FieldFox RF analyzers-the N9912A and the N9923A-are designed for installation and maintenance engineers working in the wireless, aerospace and defense industries. Designed to withstand even the toughest working conditions, they accelerate workloads with a task-driven user interface that saves time in the field. The N9912A (4/6 GHz) is the world‘s most integrated handheld analyzer for wireless installation and maintenance with seven instruments in one. The N9923A (4/6 GHz) is the world‘s most accurate handheld RF vector network analyzer, providing the best measurement stability in the industry (0.01 dB/degree Celsius) and offering the world‘s first integrated QuickCal calibration capability available in a handheld VNA. Both the N9912A and N9923A are designed for indoor and outdoor use. They are MIL-PRF Class 2 compliant, have no fans and no vents, and weigh less than 2.8 kg. ■ Agilent www.agilent.com/find/FieldFox Agilent Technologies Inc. enhanced its FieldFox RF analyzers with options for time-domain analysis and channel-power measurements. These options give engineers the features they need to more easily and quickly test their RF communications infrastructure. With FieldFox‘s time-domain analysis (Option 010) engineers can determine the individual frequency response of one of a series of reflections. Using the powerful gating function, they can remove unwanted responses such as connector mismatch or cable discontinuities. For R&D and manufacturing engineers who design circuits or fixtures, the time-domain capability is especially useful when testing devices such as transmission lines, fixtures and connectors. With it, engineers can measure, visualize and characterize device discontinuities (whether resistive, capacitive or inductive) using a suite of analysis tools, substantially shortening the time it takes to remove or fix the cause of unwanted discontinuities. The new channel-power meter (Option 311) is geared toward engineers and technicians in the wireless installation and maintenance arena. It provides a simple way to make channelized average power measurements, without requiring an external USB power sensor. The channel-power meter provides better accuracy for banded power Wireless RFID SMT Antenna with comprehensive protection for automotive applications PREMO launches a new family of its TP0702 standard, universally adopted by industry. This format provides up to 50 mV/ Apk-pk/m (for 7.2 mH) sensitivity which gives it the best sensitivity in this transponder size. The new TP0702U and TP0702U- CAP is an SMD antenna for low frequency 20 kHz-150 kHz receiver applications. TP0702UCAP provide an upper and lateral side protection with co-polyamide polyhexamethylene polymer walls, gamma radiated with high thermal stability (supports up to 290 º C) and mechanical resistance (exceeds 150 Mpa if mechanical strength). This antenna is equipped with NiZn ferrite core with high surface resistivity (> 10Mohm/mm) that provides a highly stable behavior (better than ±3%) over a wide temperature range (-40 º C to 125 º C). The new TP0702UCAP, is particularly suitable for applications such as TPMS (Tire Pressure Monitoring Systems) which requires an excellent performance under extreme conditions, according to AEC-Q200 and additional requirements as EU regulations. PREMO offers four SMT standard values, 2.38 mH, 4.91 mH, 7.2 mH and 9 mH at 125 kHz. Others inductance values and frequencies, from 340 µH to 18.5 mH, upon request. ■ PREMO www.grupopremo.com WG-Series Waveguide filter designed to cover a narrow frequency band in order to facilitate pointto-point routing of data over the network. Units maintain low loss and high rejection. This product covers narrow frequency bands above both 18 GHz and 26.5 GHz. Typical application would be to interconnect transmitters and receivers (transceivers) with antennas ■ RLC-Electronics hf-praxis 8/2012 49
