Step 2. Calculate the half power level from the data as shown in Figure 2-12.
Equation: ½ Power = Summed P
hot
Reading 201 / 2
Step 3. Use the summed value column as shown in Figure 2-12 as a look up reference and
find the cell, which closest matches the ½ Power Reading. The corresponding
frequency column is given as the center frequency point. Enter the reading into the
Test Worksheet Table on page 45 and ensure the measured value is within its
published specification.
