(2) Connect TI sensor module to signal generator No. 1 RF OUTPUT.
(3) Connect oscilloscope Vertical 1 input to A23TP1 SMPL AMPL (fig 7).
(4) Set signal generator No. 1 for an output of 18 MHz at a level of 0 dBm.
(5) Set oscilloscope for the following:
(a) Vertical 1 Coupling to AC.
(b) Vertical 1 scaling to 200 mV.
(c) Sweep speed to 10 s.
(6) Press TI keys as listed in (a) through (c) below:
(a) INSTR PRESET.
(b) DATA 18 MHz.
(c) TRACK MODE.
(7) Fine tune signal generator No. 1 up slowly until a zero beat appears on
oscilloscope. Then increase signal generator No. 1 frequency by 1 kHz. Record the
oscilloscope peak to peak amplitude as PK#1.
(9) Adjust A23R33 OFS (fig. 7) such that when the oscilloscope input coupling is
changed from ac to dc the waveform shifts upward 50 mV. Adjust only when the input
coupling is set to dc. (R)
(10) Adjust A23R54 EFF (fig. 7) for an oscilloscope indication of PK No.1 value
recorded in (7) above.
NOTE
If A23R54 EFF doesn't have sufficient range, refer to
manufacturer's manual, page 5-9.
(11) Disconnect all external equipment from TI and connect TI sensor module to TI
CALIBRATION AM/FM OUTPUT.
(12) Press TI keys as listed in (a) through (d) below:
(a)
DATA 12.1.
(b)
DATA SPCL.
(c)
DATA 46.3.
(d)
DATA SPCL.
(13) Adjust A51C20 FREQ (fig. 8) for a TI display between 1009000 and 1011000. (R)
