NOTE
If an out-of-tolerance condition is noted in (6) above, or (7)
through (23) below, perform b below.
(7) Adjust synthesized signal generator frequency to align the birdie with the end of
TI sweep as indicated on oscilloscope display.
(8) Synthesized signal generator frequency will indicate between 1.985 and 2.015 GHz.
(9) Press function keys and enter corresponding data on keyboard as listed in (a)
through (e) below:
(a)
INSTR PRESET key.
