R&S®FSQ Signal Analyzer Signal analysis and high-end ­spectrum a ­ nalysis in one instrument

R&S®FSQ Signal Analyzer At a glance The R&S®FSQ is the solution for all development and production measurement tasks. It offers very low phase noise, unsurpassed low residual EVM, a wide dynamic range and above-average accuracy, making it the ideal high-end measuring instrument for development applications, where tolerances and limit values must often be lower than defined in a standard. The ¸FSQ combines the outstanding spectrum analyzer features and functions of the ¸FSU with those of a wideband signal analyzer. Due to its large analysis bandwidth of up to 120 MHz (R&S®FSQ‑B72), the R&S®FSQ...

Excellent RF ­ erformance p for demanding applications Outstanding RF features The dynamic range performance of a spectrum analyzer is mainly defined by three parameters: ❙❙ Noise level ❙❙ Intermodulation performance (TOI) ❙❙ Phase noise The R&S®FSQ excels in all of these three categories. Its wide dynamic range comes in handy when solving d ­ ifficult measurement problems. The inherent noise level of the R&S®FSQ can be reduced by using noise correction. The instrument measures its ­ own noise in the active operating mode, and then uses signal processing to remove the noise from the trace, e...

­Signal and ­spectrum a ­ nalysis in a ­ ingle s ­instrument Signal analysis with up to 120 MHz bandwidth The R&S®FSQ combines dedicated processing hardware and the outstanding spectrum analyzer features and function of the R&S®FSU with a demodulation and analysis bandwidth that has been enhanced to 120 MHz. Best signal fidelity for modulation analysis The R&S®FSQ determines the linear distortion in the RF and IF paths with the aid of the built-in calibration source and corrects such distortion online using a compensation filter. Moreover, the bandwidth-limiting YIG filter can be switched off...

Application Phase noise and noise figure measurement The ¸FS-K40 application firmware for phase noise measurement automates measurement over a complete offset frequency range, and determines residual FM from the phase noise characteristic. In conjunction with the extremely low phase noise of the ¸FSQ, this eliminates in many cases the need for an extra phase noise measurement system that may be difficult to operate. The ¸FS-K30 application firmware for noise figure and ­ gain measurements is a convenient tool for determining the noise figure of amplifiers and frequency-converting DUTs throughout...
