20Hz至26.5GHz。 FSQ不仅继承了FSU的出色的频谱分析仪特性和功能，而且其解调和分析带宽可高达120MHz，还提供了基站频谱杂散发射和多载波测量所必需的高动态范围。因此，FSQ是进行下列产品开发和生产的理想工具：WLAN、WiMAX、WCDMA、HSPA/HSPA+、GSM/EDGE/GPRS、CDMA2000/1x EV-DO、TD-SCDMA、LTE TDD/LTE FDD、Bluetooth等。 为了解决日益增加的数据吞吐量问题，未来移动无线和相关领域对带宽的要求必然越来越高。即使今天，GSM或3GPP基站的多载波信号在功率输出阶段常常需要进行放大，尽管这样一方面可以降低技术要求和成本，但同时也增加了传输带宽。随着分析带宽要求的提高，现有频谱分析仪产品已经难于满足分析要求，市场需要具有更高分析带宽的产品，而同时满足动态范围的苛刻要求。 R&S®FSQ不仅继承了R&S®FSU的出色的频谱分析仪特性和功能，而且其解调和分析带宽可高达120MHz。因此，R&S®FSQ是进行下列产品开发和生产的理想工具： •WLAN •3GPP和 GSM-MCPA •WiMAX 除此之外，当与下列应用选件一起工作时，R&S® FSQ26还能支持2G、2.5G、3G以及4G移动无线系统的测量应用： GSM/EDGE Application Firmware R&S®FS-K5 AM/FM/PM Measurement Demodulator for R&S®FSQ/FSU/FSP/FSUP Analyzers and the R&S®ESCI/ESPI Test Receivers R&S®FS-K7 Bluetooth® Application Firmware R&S®FS-K8 Power Sensor Measurements R&S®FS-K9 GSM/EDGE/EDGE Evolution Measurements R&S®FS-K10 VOR/ILS Measurement Demodulator for R&S®FSMR/R&S®FSU/R&S®FSQ - Analysis for VOR and ILS signals R&S®FS-K15 Application Firmware for Noise Figure and Gain Measurements for R&S®FSP, R&S®FSU and R&S®FSQ (preamplifier recommended, e.g. R&S®FSU-B25) Outperforming any conventional noise measurement system R&S®FS-K30 Application Firmware for phase noise measurements R&S®FS-K40 Firmware General Purpose Vector Signal Analyzer Universal demodulation, analysis and documentation of digital radio signals This option is available for instruments for: R&S®FSUP8: as of serial number 100024 R&S®FSUP26: as of serial number 100068 R&S®FSUP50: as of serial number 100013 R&S®FSQ-K70 3GPP BTS/Node B FDD Application Firmware 3GPP transmitter measurements with R&S®FSQ signal analyzers and R&S®FSU, R&S®FSG, R&S®FSUP, R&S®FSMR, R&S®FMU and R&S®FSP spectrum analyzers R&S®FS-K72 3GPP UE FDD Application Firmware (including HSUPA) 3GPP transmitter measurements with R&S®FSQ signal analyzers and R&S®FSU, R&S®FSG, R&S®FSUP, R&S®FSMR, R&S®FMU and R&S®FSP spectrum analyzers R&S®FS-K73 3GPP HSPA+ UE Application Firmware 3GPP transmitter measurements with R&S®FSQ signal analyzers and R&S®FSU, R&S®FSG and R&S®FSP spectrum analyzers.
