(14) Adjust A4A3C55 (fig. 25) for a maximum multimeter indication.
NOTE
If A4A3C55 is at an extreme of its adjustment range (fully
meshed or unmeshed) then TI must be repaired.
(15) Short A4A3TP7 to A4A3TP8 (fig. 25) and record multimeter indication.
(16) Remove short from between A4A3TP7 and A4A3TP8.
(17) Adjust A4A3R67 (fig. 25) for a multimeter indication the same as that recorded
in (15) above 0.0005 V dc (R). If TI cannot be adjusted to meet this tolerance then TI must
be repaired.
(18) Press TI SCALE LIN key
(19) Adjust synthesizer/level generator output level for a multimeter indication of
1.000 0.002 V dc.
(20) Press TI SCALE LOG key.
(21) Decrease synthesizer/level generator output level by 50 dBm.
(22) Adjust A4A2R91 (fig. 24) for a multimeter indication of 0.500 0.001 V dc (R).
(23) Increase synthesizer/level generator output level by 50 dBm.
(24) Adjust A4A2R61 (fig. 24) for a multimeter indication of 1.000 0.001 V dc (R). If
TI cannot be adjusted to meet this tolerance then TI must be repaired.
(25) Press TI SCALE LIN key.
(26) Multimeter should indicate 1.000 0.020 V dc. If multimeter indication is out of
tolerance then TI must be repaired.
(27) Press TI REFERENCE LEVEL, 0, and dBm keys.
(28) Adjust synthesizer/level generator output level for a multimeter indication of
1.000 0.001 V dc.
(29) Press TI keys as listed in (a) through (c) below:
(a)
SHIFT.
(b)
SCALE LOG.
REFERENCE LEVEL, 60, -dBm.
(c)
(30) Decrease synthesizer/level generator output level by 10 dBm.
(31) Adjust A4A3R83 (fig. 25) for a multimeter indication of 1.000 0.010 V dc. If
multimeter indication is out of tolerance then TI must be repaired.
(32) Press TI REFERENCE LEVEL, 70, and -dBm keys.
(33) Decrease synthesizer/level generator output level by 10 dBm.
(34) Adjust A4A2R14 (fig. 24) for a multimeter indication of 1.000 0.010 V dc. If
multimeter indication is out of tolerance then TI must be repaired.
(35) Press TI 2-22 GHz key.
