The Agilent/Keysight 70907A is a downconverter module that extends the frequency measurement capabilities of 70000 series spectrum analyzers to lower frequencies. Operating as a mixer, it downconverts higher frequency input signals to intermediate frequency (IF) ranges suitable for processing by the host analyzer. This architecture enables users to analyze signals below the inherent low-frequency limit of the spectrum analyzer operating independently, significantly broadening measurement coverage across a wider signal spectrum.
