View the Spectrum Analyzers
The Keysight 3585B spectrum analyzer delivers high performance where it counts - at baseband frequencies. With very high accuracy, resolution, and dynamic range, the 3585B is a great solution for signal analysis at the critical frequencies comprising voice, video, or digital information.
The 3585B provides 80 to 100 dB of spurious-free dynamic range, a sharp 3 Hz resolution bandwidth, and a 20 Hz to 40.1 MHz frequency range to easily cover most information bandwidths. Fully synthesized tuning (including sweeps) and typical amplitude accuracy to + 0.25 dB ensure complete measurement confidence.
