R&S FSG – Spectrum analysis for mobile radio and wideband communications

September 25, 2007
Munich, 25 September 2007 — Rohde & Schwarz presents the R&S FSG, a spectrum analyzer for cost-conscious users that is tailored to meet current requirements in the development and production of wireless communication products. The R&S FSG supports all the standards of the 2nd and 3rd mobile radio generation as well as current broadband technologies such as WiMAX. Featuring a demodulation bandwidth of 28 MHz, the spectrum analyzer can already handle the measurement tasks of the UMTS LTE mobile radio generation. Its high dynamic range, a frequency range up to 13.6 GHz, and the integrated vector signal analysis make the R&S FSG a powerful tool for the general analysis of digitally modulated signals. The R&S FSG spectrum analyzer is ideal for a wide range of applications, e.g. in development labs, production lines, and as a reference for product verifications. Measurement applications for internationally common standards such as GSM, WCDMA, CDMA2000® 1xRTT, TD-SCDMA, HSPA, Bluetooth®, WLAN or WiMAX are available, if required, at the press of a button. Owing to its I/Q demodulation bandwidth of 28 MHz, a high dynamic range of, for example, 170 dB between 1 dB compression point and DANL, as well as integrated vector signal analysis, the scope of functions of the R&S FSG is ideal for modern development labs. The customized operating concept of the Rohde & Schwarz spectrum and signal analyzers also supports the user in the development of new mobile radio products. In addition, the R&S FSG provides maximum throughput in production lines. It features a high measurement speed of, for example, 2.5 WCDMA code domain measurements per second. The spectrum analyzer is also precise and reliable: With 3G, it has an inherent EVM of below 0.7 percent while offering best repeatability of the results. The R&S FSG is equipped with the same remote-control command set as all spectrum analyzers from Rohde & Schwarz. Users who already have instruments from Rohde & Schwarz will thus be able to integrate the new spectrum analyzer into their test environments without additional programming effort and keep operating costs low. The R&S FSG is available in the frequency ranges up to 8 GHz and 13.6 GHz. The spectrum analyzer provides GPIB, LAN (10/100BaseT), and USB 2.0 interfaces and is also compatible with the LXI Class C. For highly accurate determination of absolute signal powers, the R&S NRP power sensors can also be directly connected to the instrument. The R&S FSG spectrum analyzer is now available from Rohde & Schwarz.
