Measuring Other Reflection Characteristics

You can derive several important filter parameters from the measurement shown on the analyzer display. The following set of procedures is a continuation of the previous reflection measurement procedure.

Measuring Reflection Coefficient

1.Press Save/Recall RECALL STATE to recall the calibrated reflection measurement that you saved earlier in this procedure.

2.Press Format LIN MAG Scale Ref AUTO SCALE so the analyzer shows the same data in terms of reflection coefficient, as shown in Figure 2-12.

The units “mU” displayed on the analyzer are “milli-units,” where “units” or “U” is used to indicate that the parameter is unitless (as opposed to dB in log magnitude format). For example, 200 mUnits = 0.2.
