This chapter gives an overview of the controls and connectors of the frequency
converter.
4.1
Test port adapter (waveguide flange)
The test port with a mounted test port adapter is located at the front of the instru-
ment. The device under test (DUT) has to be connected to the test port adapter.

The precision waveguide flange of the test port adapter, which is compatible to
standard IEEE 1785, consists of an outer ring and a protruding inner contacting
surface with the waveguide. On the outer ring there are four UNC 4-40 threads,
two dowels and two holes as counterparts of the DUT dowels (see
).
Two additional holes in the inner flange surface allow the insertion of precision
dowels (delivered with the converter). To enhance the accuracy of the connection,
use additional dowels if the flange of the DUT also has holes for them.
