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...

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,...

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...

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...
