PRODUCT SHOWCASE COMING THIS MONTH: Entry-level R&S Spectrum Analyser with advanced-level features 18, 19 & 20TH MAY SEA WORLD GOLD COAST QUEENSLAND The 2018 WIA RADIO & ELECTRONICS CONVENTION – “BEYOND 2O2O” The latest Rohde & Schwarz spectrum analyser is the first analyser on the market to integrate the three most-commonly-used instruments on an RF engineer’s workbench, in one budget-friendly instrument. It combines a 5kHz to 1GHz Spectrum Analyser (with instant option up to 3GHz), a Network Analyser and an inbuilt Signal Generator. The R&S FPC1500 is the world’s first spectrum analyser to include a one-port vector network analyser with internal VSWR bridge, an independent CW signal generator and a tracking generator. It is ideal for education, for applications in service and repair shops and for advanced hobbyists. Despite its budget-friendly concept, the R&S FPC1500 is designed to the same quality standards as high-end Rohde & Schwarz instruments, providing solid RF performance and a comprehensive, future-ready feature set. Spectrum analyser For applications requiring a high sensitivity to characterise extremely weak signals, the R&S FPC1500 offers a low noise floor level of –150dBm (typ.), which can be further extended to –165dBm (typ.) through an optional, keycode-activated preamplifier. Its high maximum input power allows users to measure RF signals up to +30dBm (1W). This combination of high sensitivity and high input power level gives the R&S FPC1500 an exceptionally wide measurement dynamic range. Network analyser Thanks to the internal VSWR bridge, the R&S FPC1500 can perform reflection measurements. This allows users to measure impedance on antennas or RF circuits with the Smith chart display or use distanceto-fault measurements to detect faulty locations on a long RF cable. Signal generator The tracking generator integrated into the R&S FPC1500 enables scalar transmission measurements on passive and active RF components that do Contact: not produce their own Rohde & Schwarz (Aust) Pty Ltd RF signal, eg, amplifiUnit 2, 75 Epping Rd, Lane Cove NSW 2113 ers, filters and even RF Tel: (02) 8874 5188 cables.
