(8) Set BANDWIDTH switch to 1 kHz and SCAN WIDTH (red) switch to PER
DIVISION.
(9) Repeat (3) through (5) above to calculate demodulation sensitivity. (A typical
value for demodulation sensitivity with control settings given is 135 Hz/div.)
(10) Set TUNING STABILIZER switch to OFF and repeat (6) above.
(11) Measure vertical displacement and multiply by demodulation sensitivity
obtained in (9) above. Destabilized residual FM calculated must be less than 1 kHz p-p.
b. Adjustments. No adjustments can be made.
23. Final Procedure
a. Deenergize and disconnect all equipment.
b. Annotate and affix DA label/form in accordance with TB 750-25.

24. Preliminary Instructions
process. Personnel should become familiar with the applicable sections before beginning
the calibration.
b. Items of equipment used in this procedure are referenced within the text by common
name as listed in table 2.
WARNING
HIGH VOLTAGE is used or exposed during the performance of
this calibration.
DEATH ON CONTACT may result if
personnel fail to observe safety precautions.
REDUCE
OUTPUT(S) to minimum after each step within the
performance check where applicable.
NOTE
Unless otherwise specified, verify the result of each test and,
whenever the test requirement is not met, take corrective
action before continuing with the calibration. Adjustments
required to calibrate the TI are included in this procedure.
Additional maintenance information is contained in the
manufacturer's manual for this TI.
