NOTE
Use a 10 dB attenuator between TI and power meter.
Measured value will take attenuator into consideration during
calculations.
(9) Press TI Freq, 100, and kHz keys, and adjust the TI output level until the
power meter indication matches the calculated 100kHz_20dB_reference in dB minus the
attenuator test report value in dB at 100 kHz.
(10) Adjust the TI frequency to each of the frequencies listed in table 8. If the
difference between the power meter indication and the calculated 1kHz_20dB_reference
minus the attenuator test report value in dB at the selected frequencies is not within the
minimum/maximum limits listed in table 8 perform the alignment procedure in paragraph 13.
