(41) Adjust A4A3R67 (fig. 25) for a multimeter indication the same as that recorded
in (39) above 0.0005 V dc (R). If TI cannot be adjusted to meet this tolerance then TI must
be repaired.
(42) Press TI SCALE LIN key.
(43) Adjust synthesizer/level generator output level for a multimeter indication of
1.000 0.002 V dc.
(44) Press TI SCALE LOG key.
(45) Decrease synthesizer/level generator output level by 50 dBm.
(46) Adjust A4A2R91 (fig. 24) for a multimeter indication of 0.500 0.001 V dc (R).
(47) Increase synthesizer/level generator output level by 50 dBm.
(48) 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.
(49) Press TI SCALE LIN key.
(50) Multimeter should indicate 1.000 0.020 V dc. If multimeter indication is out of
tolerance then TI must be repaired.
(51) Press TI REFERENCE LEVEL, 0, and dBm keys.
(52) Adjust synthesizer/level generator output level for a multimeter indication of
1.000 0.001 V dc.
(53) Press TI keys as listed in (a) through (c) below:
SHIFT.
(a)
SCALE LOG.
(b)
REFERENCE LEVEL, 60, dBm.
(c)
(54) Decrease synthesizer/level generator output level by 10 dBm.
(55) 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.
(56) Press TI REFERENCE LEVEL, 70, and dBm keys.
(57) Decrease synthesizer/level generator output level by 10 dBm.
(58) 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.
(59) Press TI 2-22 GHz key.
(60) Disconnect synthesizer/level generator 50
OUTPUT from TI RF INPUT.
