Single connector for a HG cable, and two HM connectors
MVNA-8-350-2 - AB Millimetre (AB Millimetre)
The lower part of the Central Unit model MP-8-350-2 has a single connector for a HG cable, and two HM connectors (Fig. 9). Two Harmonic Mixers can work simultaneously, for instance HM2 detecting transmission through the DUT, and HM1, at port 3 of a directional coupler, detecting reflection from the DUT.
