3. Perform step 4 through step 29 using the information and entries 
from Table 2-74. Then continue with step 31 through step 43.
4. Press PRESET on synthesized sweeper 1. Set the CW frequency to F1 
as indicated in Table 2-74, and set the power level to 4 dBm.
5. Press PRESET on synthesized sweeper 2. Set the CW frequency to F2 
as indicated in Table 2-74, and set the controls as follows: 
POWER LEVEL, –10 dBm
RF Off
6. Enter the power sensor calibration factor for F1 into the power 
meter.
