The HP 70001A/70908A RF Section is a modular component for the HP 70000 Modular Measurement System (MMS), delivering broadband input conversion across 100 Hz to 22 GHz. The RF section uses fundamental mixing technology with a dynamically tracked preselector to optimize sensitivity and dynamic range for spectrum and lightwave signal analysis. The system combines the HP 70001A mainframe—which provides housing, power distribution, and dual communication interfaces (MSIB and GPIB)—with the HP 70908A RF module and HP 70810A lightwave receiver to create a flexible measurement platform for demanding RF and optical applications.
