BETTER OPTICS = BETTER SYSTEM PERFORMANCE PRODUCTUPDATE SPECIAL FOCUS: Time and power savers Anritsu antenna analyzer touts long battery life Actual image Edmund Optics® – Performance at the Edge The Site Master S331L handheld cable and antenna analyzer from An- ritsu delivers eight hours of continu- ous battery operation to allow field technicians to conduct a full day's testing on a single charge. Covering NI offers LabView/AWR VSS cosimulation Actual image Competitor – Performance at the Edge WANT TO SEE THE FULL TEST? to see how Edmund Optics® outperforms a frequency range of 2 MHz to 4 GHz, this one-port analyzer mea- sures return loss, VSWR, cable loss, distance-to-fault return loss, and dis- tance-to-fault VSWR. Anritsu reports that the S331L has the highest RF immunity of any Site Master analyzer. A sweep speed of 1.5 ms per data point (typical) en- ables identification of intermittent problems in real time. The S331L also features a built-in power meter for testing RF power from 50 MHz to 4 GHz and built-in InstaCal module, which provides fast one-connection calibration. Power-saving functions, such as a sleep mode and automatic display brightness, can extend bat- tery life beyond the continuous eight-hour rating. more optics | more technology | more service USA: Call for Better Optics in Your System +1-856-547-3488 EUROPE: +44 (0) 1904 788600 ASIA: +65 6273 6644 JAPAN: +81-3-5800-4751 The S331L has a backlit 7-in. TFT touch-screen display and can store more than 1000 files, including sweeps, setups, and screenshots. In addition, it comes with SweepMas- ters Direct, a trace-delivery service that allows users to capture, upload, and deliver traces. The compact ana- lyzer weighs less than 4.4 lbs and is both dust- and splash-resistant. Price: $6750. Anritsu, To unify RF/microwave design and test, National Instruments an- nounced connectivity between Lab- View system design software and AWR VSS (Visual System Simulator) software for communications system design. As the first major joint devel- opment between NI and AWR fol- lowing NI's recent acquisition of AWR, the new connectivity helps en- gineers make better use of measure- ments in the design flow by execut- ing LabView code directly from the AWR design environment. Cosimulation within the AWR de- sign environment is enabled through a LabVIEW element on the VSS dia- gram. The AWR design environment can now incorporate LabView signal- processing capabilities, including mul- tirate digital signal processing, wire- less standards, modulation, and fixed-point math. Engineers can inte- grate VHDL and LabView FPGA mod- ule code through NI FPGA-based hardware directly into VSS diagrams. In addition, new connectivity to both PXI and conventional RF instrumenta- tion makes it easier to incorporate measurement data into simulations. A whitepaper is available at www. GAO portable ADSL2+ tester multitasks The Model A0010002, a portable ADSL2+ tester from GAO Comm, lets field technicians test the physical layer, network layer, and phone lines in accordance with ADSL, ADSL2+, and Re-ADSL (reach-extended) stan- dards. It also functions as a digital multimeter and can even conduct tests while the operator browses pre- vious test records. Network layer tests include ping, IP config, route, and tracert.
