The HP 85106D mm-wave S-parameter network analyzer is a banded waveguide system. Table 1-1 lists the waveguide bands available from 33 GHz to 110 GHz. You must add two HP 85104A series test set modules for each waveguide band. For fully error-corrected measurements, it is necessary to use a calibration kit in the same frequency band as the test set modules being used.

A sliding load may also be used to determine directivity. The load element is moved to five (or more) positions determining corresponding points of the circle of Figure 2-4c. The HP 8510C then uses a circle-fitting routine to determine the center of the circle which is the actual directivity. Again, the effective directivity is determined by the dimensions of the line.
