Latest testing and diagnostic products.Dual-purpose test setTEST BOTH VOICE AND HIGH-SPEED DATA SERVICES simultaneously with one piece of equipment, saving time and expense. The TS 1200 ADSL/POTS test set is a combination data-safe, butt-in test set and ADSL See DSL. ADSL - Asymmetric Digital Subscriber Line service tester. Two modes of ADSL testing provide both an automatic test to provide a snapshot of the line, and a manual test that can monitor line conditions for up to 90 minutes. The easy-to-read menu options, digital readouts and graphing capabilities assist technicians in diagnosing problems. Standard features include high-voltage protection, DropSafe and RainSafe technologies, PBX (Private Branch eXchange) An inhouse telephone switching system that interconnects telephone extensions to each other as well as to the outside telephone network (PSTN). pause, speed dial, last number redial, and tone/pulse dialing.--Harris www.harris.com Circle 315 for more information AUTOMATED FIBER-OPTIC TEST SYSTEM allows the efficient testing of ribbon cables in telecommunications and networking environments. The Ribbon Test System (RTS (Request To Send) An RS-232 signal sent from the transmitting station to the receiving station requesting permission to transmit. Contrast with CTS. 1. (operating system) RTS - run-time system. 2. ) performs return- and insertion-loss measurements on terminated fiber-optic ribbon cables, MT-RJ MT-RJ Mechanical Transfer - Registered Jack patchcords and other multifiber cables. The system obtains, records and processes measurement data, and generates custom reports. A software package running on a PC-compatible workstation controls the test unit through a GPIB/IEEE-488 interface. The RTS permits the concurrent insertion-loss and return-loss measurements on up to 64 fibers at one time, eliminating the need for time-consuming mandrel mandrel /man·drel/ (man´dril) the shaft on which a dental tool is held in the dental handpiece, for rotation by the dental engine. man·drel or man·dril n. 1. wraps. The system can test different cable types simultaneously, and can be customized for specific manufacturing or research applications.--RIFOCS www.rifocs.com Circle 313 for more information TEST THE LATEST DIGITAL WIRELESS FORMATS without replacing costly testing equipment. The 2029 Vector Modulator can turn any analog RF signal generator into a digital signal generator for testing digital wireless products, including base station amplifiers. Coupled with any manufacturer's analog RF signal generator, the 2029 can output digital signals in WCDMA (Wideband CDMA) A 3G high-speed digital data service provided by cellular carriers that use the TDMA or GSM technology worldwide, including AT&T (formerly Cingular) and T-Mobile in the U.S. , CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. 2000, IS-95, GSM, IS-136 and EDGE. The unit combines a vector modulator, an arbitrary waveform generator An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms. These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external). and an RF level-control system. The 2029 supports multiband, multimode phones, and can test 2G, 2.5G and 3G formats, with a frequency range from 800 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. to 2.51 GHz. The system is able to switch digital formats instantly, and a software upgrade feature enables the 2029 to keep up with changing wireless standards.--IFR Systems www.ifrsys.com Circle 312 for more information Wireless sweeper EASILY LOCATE ACCESS POINTS and measure coverage in DSSS (Direct Sequence Spread Spectrum) See spread spectrum. wireless networks. The Grasshopper is a 2.4 GHz WLAN See wireless LAN. WLAN - wireless local area network wireless receiver designed specifically, for sweeping and optimizing LANs. The instrument measures packet error rate, and displays correlated power and total channel power for direct sequence networks that operate on the IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 802.11b standard. The Grasshopper detects and differentiates from narrow-band multipath interfaces, such as microwave ovens and frequency-hopping systems, and includes a built-in display, keypad and antenna. The unit features an easy-to-read backlit display to show the received signal strength graphically. The sweeper comes with a rugged, water-resistant carrying case and two removable battery packs.--Berkeley Varitronics Systems www.bvsystems.com Circle 314 for more information Gigabit Ethernet analysis GAIN VISIBILITY OF CRITICAL HIGH-SPEED LINKS with a hardware/software system for monitoring, analyzing and reporting network activity. The Gigabit Distributed Vision Suite integrates two Windows-based software packages--Protocol Inspector Version 3.0 and Network Inspector Version 4.1--and distributed hardware analyzers together to maximize effectiveness in locating and correcting network problems at 10/100 Mbps or gigabit speeds. A Network Inspector software module automatically performs network device discovery and trending of port-level traffic on switches and routers, without the expense of outfitting each port. Results can be integrated into reports that may be printed, published to Web pages or passed to Microsoft Visio 2000 for network diagramming. The hardware analyzers feature full-duplex, full-line-rate 10/100 ethernet and new Gigabit Ethernet versions in self-contained rackmounted units. A supplied in-line tap allows nonintrusive monitoring on fiber or copper links, eliminating the need to break and re-enable network connections each time a network segment is analyzed.--Fluke Networks www.flukenetworks.com Circle 311 for more information |
