ENTRY knob for a power meter indication of -10.00 dBm f0.03
ENTRY knob (REF in dBV with ATN: 0 dB) for a power meter
indication of -10.00 dBm *0.03 dB at 100 MHz.
Do not vary the synthesized sweeper POWER LEVEL setting
(internal leveling) or XTAL REF and XTAL ATN settings (external
diode detector leveling) for the remaining steps in this adjustment
procedure. The frequency response adjustments are referenced to
-10.00 dBm power level at 100 MHz.
56. Disconnect the power sensor from the power splitter, and
connect this power splitter resistive output to the spectrum
analyzer RF INPUT using an APC 3.5 (m) to Type N (m) adapter.

YTX Drive adjustments A6A12R63 5.8 GHz and A6A12R66 2 GHz are
interactive and affect YTX/YTO tracking in all preselected frequency
bands (Bands B, C, D, and E, 2 GHz - 22 GHz).
58. Adjust 25-turn (YTX Drive) potentiometer A6A12R63 5.8 GHz
