10.Press .
11.Record the power meter reading in the first column of Table 3-2.
12.Repeat the previous two steps at 50 MHz, 1.5 GHz, and 3 GHz.
13.For Option 006 Instruments Only: Make a measurement at 6 GHz by disconnecting
the 8482A (sensor A) from the power splitter, and replacing it with the 8481A (sensor
B).
• If you are using the 438A power meter, the 8481A should be connected to the meter's
channel B input.
• If you are using the 437B power meter, zero and calibrate the 8481A sensor.
14.Reconfigure the equipment as shown in Figure 3-3.
