2.1 Test Port Adapter (Waveguide Flange)
The test port with a mounted test port adapter is located at the front of the instrument.
The device under test (DUT) has to be connected to the test port adapter.

ZVA-Z500 (the other models are similar in design)
The precision waveguide flange of the test port adapter is equipped with two alignment
pins and two holes receiving the alignment pins of the DUT (see
figure 2-2
). Two addi-
tional holes in the middle allow to insert additional alignment pins (delivered with the
instrument). Additional pins should be used if the flange of the DUT also has holes for
receiving these pins and the accuracy of the connection shall be enhanced.

The R&S ZVA-Z110 converter is delivered with a standard adapter plus an alternative
adapter. The two adapters differ in the size of the holes receiving the alignment pins of
the flange of the DUT. The standard test port adapter has holes with a diameter of
