NOTE
Ensure receiver system is in measurement mode.
(42) Disconnect fixed short from equipment setup in figure 5.
Figure 5. VSWR waveguide (18 to 26 GHz) - equipment setup.
(43) Zero power meter No. 1 and connect TI to directional coupler No. 3, point A (fig.
5). Record receiver system readout indication as return
loss.
(44) Remove TI from directional coupler and connect fixed short to directional coupler
(45) Repeat (41) through (44) two more times and average values recorded in (43)
above. Determine VSWR using appendix B. VSWR will be within the limits listed in
