(3) Press RF BLANK key (ON) and adjust oscilloscope controls as necessary to
display the TI sweep.
(4) Adjust synthesized signal generator frequency and output level controls until a
birdie (notch) appears on oscilloscope display (approximately 1 GHz).
(5) Adjust synthesized signal generator frequency to align birdie with the start of TI
sweep as indicated on oscilloscope display.
(6) Synthesized signal generator frequency will indicate between 0.985 and 1.015 GHz.
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.
