Spectrum Analyzer Extension Modules
OVERVIEW
Description
Virginia Diodes, Inc. (VDI) Spectrum Analyzer Extension (SAX) modules provide high performance broadband down-conversion and frequency extension of microwave spectrum analyzers into the THz range. VDI SAX modules offer full waveguide band coverage and are available from WR15 (50 to 75 GHz) to WR1.0 (750 to 1100 GHz) with additional bands under development.
For spectrum analyzer extension mode, this turn-key, sweepable solution is compatible with most modern spectrum analyzers with external mixer option. For block down- and up-conversion, the SAX modules can be driven by an LO signal generator that meets the input frequency and power requirements. Contact VDI for spectrum analyzer extension compatibility.
