IFR launches improved spectrum analyzer
IFR announced an improved version of the 2399 spectrum analyzer designed to meet the needs of the cellular manufacturing and test market by making a higher frequency range instrument available at a lower price.
The 2399A is a color 9 kHz to 3 GHz spectrum analyzer that replaces IFR’s existing 2399 spectrum analyzer. It offers a lower noise floor of -125 dBm at a price of $8,700 — a drop of $900 over the 2399.
The 2399A can be ordered with an optional digital resolution bandwidth filters (DRBW). The filters are generated digitally at 100Hz, 30 Hz and 10 Hz to allow finer resolution, reducing the effective noise floor by 5 dB.
The lightweight (less than 21 lbs.) unit features a large color LCD display, a fast processor and a large memory capable of storing up to 1,000 screen traces and 2,000 operational states. Its 50-ohm input can accept signals between +30 dBm and -120 dBm while providing protection up to 50 VDC. The comprehensive marker system allows as many as nine markers to be displayed at any one time, together with a marker table showing the frequency and level of each marker selected. This feature allows multiple signals to be evaluated simultaneously. In addition to Normal Markers, the 2399A provides Delta Markers, Peak Search, Peak Track, 1/Delta, Marker Track, Marker to Center, and Marker to Reference capability.
The instrument can be ordered with a full-range tracking generator, high stability time base, and quasi-peak detectors for EMC-compatibility testing and digital resolution bandwidth filters, Its pricing at US $9,048.
Cisco introduces mobile access router
Cisco Systems Inc. announced the Cisco 3200 series mobile access router, a new solution for mobile vehicular applications. The router is designed to facilitate the mobility of networks in motion — entire networks of communication devices in moving vehicles such as airplanes, ships, tanks and trains — and is designed for “always-on” connectivity.
It is a compact access router that is designed to provide security in data, voice and video communications, and seamless mobility and interoperability. Enabled by standards-based mobile IP, the router extends the edge of the IP network, delivering mission-critical applications for the defense, public safety and commercial transportation markets.
It also includes Mobile Networks Software that allows an entire network, not just a single client, to stay connected while in motion.
Site Master cable and antenna analyzer
Covering the 2 MHz to 1.6 GHz frequency band, the Site Master S113C/S114C site management tools are designed to accurately locate and identify RF cable feed-line and antenna system faults. These models are ideally suited for any experience user in commissioning and maintenance of today’s wireless communication system infrastructure including VHF, cellular and GPS applications.
The system’s measurement capability includes return loss, VSWR, cable loss and distance-to-fault (DTF) analysis. RF interference rejection enables accurate, repeatable measurements in the presence of high RF activity. Data analysis software enables assessment of system trends, problems, and performance in addition to professional report generation. An optional power meter is available to make power measurements quickly and easily.
It features spectrum analysis capability in addition to measurement capability, allowing technicians and field engineers to identify and solve RF system problems such as coverage, interference and other path related signal problems. Its spectrum analysis ranges from 100 kHz to 1.6 GHz.
The system’s models include data analysis software, soft carrying case, rechargeable/field-replaceable battery, AC/DC power supply, 12.5 VDC automobile cigarette lighter adapter and users guide.
Antenna Specialists marries technologies
The Tele-Locator Dual-System mobile antenna combines both GPS and 900 MHz technologies in a single, cost-effective antenna to offer two-way communication and GPS location services.
It allows for customers with GPS capabilities to also have two-way 900 MHz communications — without the expense and often-unwanted appearance of two single function antennas on the vehicle.
This antenna facilitates integrated voice and data wireless service along with the benefits of GPS location capabilities to provide a solution to the E911 problem for wireless phone users. For example, this antenna allows the use of an in-vehicle GPS system to identify the location while the cellular phone can be used to summon assistance. Additionally, trucking fleets are able to track their assets while having nationwide wireless communications access simultaneously.
Centurion Wireless unveils first multi-band, 3G antenna
Centurion Wireless Technologies has announced the availability of the Multi-Band Microsphere antenna.
It is designed to enhance mobile phone connectivity inside buildings. It provides simultaneous, omni-directional coverage in all major global mobile communications frequency bands including AMPS, GSM, DCS, PCS and UMTS.
The antenna offers a broad range of indoor coverage for five frequency bands covering Cellular at 806-894 MHz, GSM at 880-960 MHz, PCS at 1850-1990 MHz, DCS at 1710-1880 MHz and UMTS at 1990-2170 MHz. It can eliminate the need for multiple in-building antenna installations. The antenna offers peak gains of 2.7 to 4.5 dBi. The antenna can be mounted directly on any ceiling and its extremely small form factor ensures that once installed it is practically invisible.
The antenna can also provides carriers with an upgradeable path to 3G as these services are rolled out. In the interim, it will allow wireless carriers operating on a single frequency band to create multi-carrier networks with other service providers that accommodate the full range of different services in use by mobile subscribers.
