Determining Characteristics After Adding a Matching Circuit
7. Fixture Simulator
Step 5. Press Select Circuit.
Step 6. Select a matching circuit model (Figure 7-5).
Softkey Function
None No matching circuit is added.
Series L - Shunt C Selects a circuit model consisting of a series inductor and a shunt
capacitor
Shunt C - Series L Selects a circuit model consisting of a shunt capacitor and a series
inductor
Shunt L - Series C Selects a circuit model consisting of a shunt inductor and a series
capacitor
Series C - Shunt L Selects a circuit model consisting of a series capacitor and a shunt
inductor
Shunt L - Shunt C Selects a circuit model consisting of a shunt inductor and a shunt
capacitor
User Selects the circuit model defined in the user file imported by
performing
Step 4
Step 7. Specify the values of the elements in the selected circuit model.
Softkey Function
C Specifies capacitance [F]
G Specifies conductance [S]
L Specifies inductance [H]
R Specifies resistance [Ω]
NOTE When either of the two components of Series-C, "C" and "G", is set to 0, the component is
defined as "Open"; when both components are set to 0, they are defined as "Short."
When either of the two components of Shunt-L, “L” and “R”, is set to 0, the component is
defined as "Short"; when both components are set to 0, they are defined as "Open."
Step 8. Repeat Step 3 to Step 7 to set up the matching circuit for each port used.
Step 9. Press Port Matching to turn the matching circuit function ON.
Step 10. Press Return.
Step 11. If Fixture Simulator is OFF, press the key again to turn it ON.
