NOTE
When indications specified in this procedure are not within
tolerance, perform the power supply check prior to making
adjustments.
a. Connect TI to 115 V ac power source.
b. Press power key to on and allow at least 30 minutes for TI to warm-up and stabilize.
a. Performance Check
NOTE
In the following procedure, any source can be connected either
to a sensor module (as written) or directly to the TI INPUT 50 Ω.
(1) Press TI BLUE key and then press TI INSTR PRESET key.
(2) Connect TI CALIBRATION AM/FM OUTPUT to TI sensor module.
(3) Press TI keys as listed in (a) and (b) below:
(a) MEASUREMENT AM.
(4) Allow TI to take at least two readings. If TI indication is not between 99 and
101 percent, perform b below.
(5) Press TI keys as listed in (a) and (b) below:
(a) DATA 2.2.
(b) DATA SPCL.
(6) Allow TI to take at least two readings and record this reading. If TI indication is
not between 99 and 101 percent, perform b below.
NOTE
Record indication in step (6) for future reference.
(7) Set the AM/FM test source TEST MODE switch to AM.
(8) Connect AM/FM test source AM OUTPUT to TI sensor module.
NOTE
Nothing should be connected to the AUDIO INPUT of the test
source.
(9) Press TI keys as listed in (a) and (b) below:
(a) MEASUREMENT FREQ.
(b) TRACK MODE.
(10) Adjust AM/FM test source CARRIER FREQUENCY TUNE control for a TI
indication of approximately 12.5 MHz.
(11) Press TI keys as listed in (a) through (f) below:
(a) TRACK MODE.
(b) MEASUREMENT AM.
(c) DATA 2.0, SPCL.
