FSP3 Rohde & Schwarz Spectrum Analyzer


The FSP3 is a 3 GHz Spectrum Analyzer from Rohde & Schwarz. A spectrum analyzer measures the power of spectrums of known and unknown signals. Spectrum analyzers collect information such as the magnitude of an input signal compared to its frequency. As a frequency analyzer, spectrum analyzers’ main use is to document and analyze electrical input signals as well as spectral compositions of other signals.

The ideal partner for both development and production, featuring good level measurement uncertainty, as well as excellent RF characteristics. The R&S FSP3 incorporates proven technology to enable best performance, reliability and ease of service. The Rohde & Schwarz FSP3 Spectrum Analyzer is capable of testing spurious emissions stipulated in the GSM specifications and has a firmware to allow adjacent-channel power (ACP) measurement to the W-CDMA/third-generation partnership project (3GPP).

This measurement is implemented in the Rohde & Schwarz FSP3 by automatic test routines which make all necessary settings, measurements and filtering. The electronic attenuator for a spectrum analyzer increases the availability for use in production and allows a number of switching operations in a wear-and-tear-free setting range of 30 dB in 5 dB steps.
