Ideal for satellite RF testing

High-performance measurement solutions for designing, developing and testing satellite payloads, payload subsystems and components

The R&S®FSW offers dedicated measurement applications for the most critical measurements such as group delay, linearity, gain transfer, noise power ratio (NPR), etc. It also demodulates satellite RF signals of several standards such as DVB-S2X and OneWeb. The R&S®FSW scalable, wide analysis bandwidth (up to 8.3 GHz) meets the increasing demand for wide signal bandwidths.

**R&S®FSW-K17 multicarrier group delay measurements.** - Measures absolute and relative group delay with high accuracy within milliseconds.

Real-time spectrum analysis

Don’t miss a thing with the real-time spectrum analysis option

The R&S®FSW real-time options allow users to reliably detect extremely short sporadic interference in the nanosecond range even in close proximity to powerful carriers – in a bandwidth of up to 800 MHz. Real-time spectrum analysis enables users to analyze existing frequency hopping algorithms and create alternative ones to prevent collisions between signals of different standards operating in the same frequency band.

**Real-time spectrum of the ISM band at 2.4 GHz.** - Analyzes and prevents collisions between signals of different standards operating in the same frequency band (e.g. WLAN and Bluetooth®).
