Portable Spectrum Analyzer Extenders (PSAX)

OVERVIEW

Description

Virginia Diodes, Inc. (VDI) Portable Spectrum Analyzer Extension (PSAX) Modules are used to extend the performance of modern handheld / portable spectrum analyzer solutions (e.g. Keysight FieldFox) in the frequency range from 50 GHz through 170 GHz, in frequency bands from WR-15 (50-75 GHz) to WR-6.5 (110-170 GHz). Higher frequency PSAX modules are available. An external battery or power supply may be needed to operate higher frequency PSAX modules.

Direct Connect to Keysight FieldFox Analyzers

The VDI PSAX Module is designed to connect directly to the RF Ports on the Keysight FieldFox Analyzers. The IF connector on the PSAX module can be adjusted laterally to be compatible with the LO and IF port spacings of all Keysight FieldFox analyzers.
