The Rohde & Schwarz FSP3 is a high-performance general-purpose spectrum analyzer covering the 20 Hz to 3 GHz frequency range. It is designed for demanding development and production environments, featuring an exceptionally low total measurement uncertainty of 0.5 dB, fast measurement speeds up to 80 measurements per second, and a wide array of standard evaluation routines (TOI, ACPR, OBW, CCDF, APD). With an innovative hardware design, standard electronic attenuator, and advanced filtering options, the FSP3 delivers outstanding RF characteristics and high throughput.
