High measurement speeds are crucial for production testing of wireless communications components and base station test systems. Rohde & Schwarz developed the FPS signal and spectrum analyser specifically for these types of automated measurement applications. With a height of two height units (2 HU), the compact R&S FPS takes up only half as much rack space as a conventional spectrum analyser.
The FPS signal and spectrum analyser is available in five models for frequency ranges up to 4, 7, 13, 30 and 40 GHz. It offers measurement applications for all key mobile and wireless standards and can demodulate IEEE 802.11ac Wi-Fi signals thanks to its 160 MHz analysis bandwidth. The higher frequency models are suited for satellite monitoring applications and for the production of components for the aerospace and defence industry.
Rohde & Schwarz equipped the R&S FPS with state-of-the-art processor technology, enabling it to perform CPU-intensive tasks especially fast. For WCDMA signals, for example, it calculates the adjacent channel leakage ratio of four adjacent channels (two on each side) in less than 10 msec while maintaining a standard deviation for the power reading of less than 0.05 dB – unmatched performance among instruments in this class. The R&S FPS also analyses the modulation of wireless communications signals during component production faster than any comparable instrument while maintaining consistent precision over the entire frequency range.
Used alongside a signal generator such as the R&S SGS100A, the two instruments together can be used as a mini system for T&M applications requiring fast interaction between a signal generator and signal analyser, such as when testing mobile phone power amplifiers. A small display on the front of the instrument shows relevant status information such as the IP address being used.
