(11) Disconnect W7P1 (red) cable from A10J2 connector (located on Al0 assembly)
and connect signal generator RF output to W7P1 (red) cable.
(12) Adjust signal generator frequency to 301.4 MHz and RF output level
controls to -30 dBm.
controls to peak signal on crt.
(14) Adjust signal generator RF output level controls to position signal 7.1 divisions
above graticule baseline.
controls to peak signal on crt.
(16) If signal is not positioned 7.1 graticules above graticule baseline, adjust A11R2
(located on A11 board) and A13R2 (located on A13 board) equally for a signal 7.1 divisions
above graticule baseline(R).
(17) Record signal generator frequency.
(18) Adjust signal generator frequency 500 Hz below value recorded in (17) above.
(19) Adjust A8R1 (located on A8 board) to position the signal level on the 5th
graticule line from the graticule baseline (R).
(20) Repeat (15) through (19) above until frequency change from center frequency at
7.1 divisions to the 3 dB point of the 5th graticule line is between 450 and 550 Hz.
(21) Connect W7P1 (red) cable to A10J2 (located on A10 assembly).
NOTE
Perform (22) through (44) below for SN prefixed 2332A, 2215A,
and below.
(22) Set RESOLUTION BW and FREQ SPAN/DIV switches to settings as listed in
table 6. If bandwidth at 5th graticule line above graticule baseline is not within the
specified limits, perform (23) below.
