AMPLITUDE : :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: : 03 dBm

6. Set the power meter to the following settings:

MODE ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: ::: :: :: : dBm

CAL FACTOR : :: :: ::: :: : power sensor Ref Cal Factor for 50 MHz

7.Adjust synthesizer/level generator power level for a 06.99 dBm (60.03) reading on the power meter.

8.Record the synthesizer/level generator amplitude setting in Table 2-80 under Reference Amplitude at 50 MHz for the 200 Hz, 9 kHz and 120 kHz EMI bandwidths.

9.Calculate the Required Amplitude for each EMI bandwidth using the following formula and enter each calculated Required Amplitude values in Table 2-80.

Reference Amplitude at 50 MHz + Amplitude O￿set = Required Amplitude

Note that the reference amplitude is the same for the 200 Hz, 9 kHz, and 120 kHz ￿lters.

10.On the synthesizer/level generator, press 4STORE5 1 to store the previous setting of the synthesizer/level generator in storage register 1.
