1. Fixings S Pe jscrews Fig l Position of the stop circuit coil Fig 2 probe connectors 2 Changing between 2 2 and 2 4 mode 1 Incase of operating in A 2 mode frequency range see list it is necessary to remove the short circuit screw at the 2 tube of the H channel see Fig 3 below In the other case in 4 4 mode frequency range see list use the marker at the A 2 tube and carefully turn in the screw equally and continously until one has contact with the inner conductor of the A 2 line Do not turn this screw too far in order to avoid bending or damage of the inner conductor Slide on the shielding tube and lock it 2 First tune and match H and then X and Y Repeat this procedure for fine tuning Fig 3 screw out gt A 2 mode Fig 4 screw in gt 4 mode 2 Adjustment for Optimization of the stop circuit frequency 1 Adjust the stop circuit frequency by turning the black rod at the bottom of the probe see Fig 5 and observe the insolation at the Network Analyzer see Fig 6 and Fig 7 Fig 6 C stop circuit frequency not optimized Fig 7 C stop circuit frequency optimized2.
