260A Millimeter Head Controller
The N5260A millimeter head controller provides the test interface between the millimeter-wave
test head modules and the E8361C H11 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 process
and display. The N5260A millimeter head controller also supplies the +12 volt bias to each
millimeter-wave head module.
The front panel of the N5260A millimeter head controller is illustrated below.
For additional information, see the N5260A Operation and Service Guide. If a printed version of
the N5260A manual is not available, refer to “Printing Copies of Documentation from the Web” on
page ii of this manual.
