This unit
The HP/Agilent 3585B is a spectrum analyzer covering 20 Hz to 40 MHz, engineered for precise baseband signal analysis in voice, video, and digital applications. This instrument delivers 80–100 dB spurious-free dynamic range with amplitude accuracy of ±0.25 dB across a measurement span of −137 dBm to +30 dBm. The 3 Hz minimum resolution bandwidth, combined with selectable 50 Ω, 75 Ω, and 1 MΩ input impedance, enables detailed characterization of low-level signals in complex environments.
