N5261A and N5262A Millimeter Head Controllers
The N5261A and N5262A millimeter head controllers provide the test interface between the
millimeter-wave test head modules and the N5227A PNA series network analyzer.
The millimeter head controller, when used in conjunction with the millimeter-wave test head
modules and the PNA, provides all of the feature and functions of a full S-Parameter test set.
The millimeter head controller supplies RF and LO signals to the millimeter-wave test head
modules and returns the down converted reference and test IF signals to the PNA for processing
and display. The N5261A and N5262A millimeter head controllers also supply the +12 volt bias to
each millimeter-wave head module.
The front panels of the N5261A and N5262A millimeter head controllers are illustrated below.
