The DPL Series offers compatibility with OML’s MxxHWD harmonic mixer series for external mixer applications. In this popular spectrum analysis scenario, the DPL Series provides external diplexer functionality when integrated capabilities are not available in the destination spectrum analyzer (e.g., Keysight’s PSA E444xA Series). As a standalone component, the diplexer is also compatible with Keysight’s 11970 waveguide mixers for use with Keysight’s PXA N9030A.
