Front view
At the front, the R&S SZU covers the interface to the DUT that is the output of the RF signal. To connect the device under test (DUT), you can directly connect it to the waveguide flange, or use one of the available test port adapters.
The RF waveguide port of the R&S SZU is a standard WR15 waveguide flange that consists of an outer ring and an inner contacting surface with the waveguide. The outer ring provides four alignment fixtures, two cylindrical pins and two holes as counterparts of the DUT alignment pins.
See "To connect the DUT to the R&S SZU directly".
Rohde & Schwarz provides either a waveguide-to-waveguide adapter, and a waveguide-coax-adapter. Refer to the data sheet for details on the type of waveguide adapters that match to the frequency band of the R&S SZU I/Q upconverter.

Designation: waveguide-to-waveguide adapter WR15, order number 1314.5780.00.
The precision waveguide flange of this test port adapter consists of an outer ring and a protruding inner contacting surface with the waveguide. On the outer ring there are four alignment fixtures, two cylindrical pins and two holes as counterparts of the DUT alignment pins. Two additional holes in the inner flange surface allow you to insert additional pins.

Designation: R&S WCA70 waveguide-coax adapter WR15-1.85 mm, order number 1314.5001.02.
The waveguide-to-V-adapter has an 1.85 mm coaxial output socket for connecting the DUT.
