Step Action
12 To generate a pattern, enter the following command:
fl_pattern 3
13 On Agilent E4406, set Spectrum (Freq Domain) measurement as follows:
S Press Measure button
S Press More button until Spectrum (Freq Domain) option is displayed
S Select Spectrum option
S Press SPAN key to set its value to 4 [MHz]
S To set the frequency value. press Frequency and enter the value calculated as follows:
– <tx_base_band_value> + 0.05*<chan_no> [MHz]
14 Use the formula from step 13 to calculate the four frequencies to measure the Power.
S check_point_1 = freq – 750 [kHz]
S check_point_2 = freq + 750[kHz]
S check_point_3 = freq – 1980 [kHz]
S check_point_4 = freq + 1980 [kHz]
15 Press MARKER key:
S Select 1, 2, 3, or 4 (frequency points)
S Press FUNCTION key and select Off option
S Press TRACE key and select Spectrum option
S Press NORMAL key
S Use the numeric keypad to enter the calculated frequency, assigning the proper unit.
S Note the Power value of marker
S Repeat step for all calculated frequency checkpoints
The check point values are as follows:
S Check_point_1 > –40 dBm
S Check_point_2 > –40 dBm
S Check_point_3 > –60 dBm
S Check_ point_4 > –60 dBm
