N5250A Millimeter-Wave Test Head Modules
Millimeter-Wave Test Head Modules
A pair of 67-110 GHz millimeter-wave test head modules, in conjunction with the N5260A millimeter head
controller, is used to make reflection, transmission, or S-parameter measurements at millimeter wave
frequencies with the E8361C H11 PNA. These test head modules are manufactured by OLM, Inc.

“Band Solutions from OML, Inc.©” on page 2- 11 for additional information.
The N5250C system measurement ports, Port 1 and Port 2, are in the left and right millimeter-wave test head
modules, respectively.
The left and right test head modules are illustrated in Figure 2-4 on page 2-7. Each test head consists of a
combiner assembly and a waveguide module. The combiner assembly contains a coupler and combiner, and
optionally contains a bias-tee (N5250C, Options 017 and 018). The multiple-connector panels provide
connections between the test head module, the N5260A millimeter head controller, and the E8361C H11
PNA.
