(13) Repeat technique of (12) above at function/arbitrary generator frequencies of 50
and 80 MHz. Function/arbitrary generator amplitude will not exceed 25 mV at 50 MHz, or
50 mV at 80 MHz.
b. Adjustments
(1) Connect signal generator to 525 MHz jack, using adapter and cable.
(2) Press 1 kHz RESOLUTION pushbutton.
(4) Adjust A1R5 (fig. 1) for stable indication of applied frequency on measuring
system (R).
(5) While reducing signal generator amplitude, continue adjusting A1R5 until
maximum sensitivity is obtained.
a. Deenergize and disconnect all equipment and reinstall protective cover on TI.
b. Annotate and affix DA Label/Form in accordance with TB 750-25.

24. Preliminary
Instructions
a. The
instructions outlined in
paragraphs 24 and
25 are preparatory to the
calibration
process. Personnel should become familiar with the entire bulletin before beginning the
calibration.
b. Items of equipment used in this procedure are referenced within the text by common
c. 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.
WARNING
HIGH VOLTAGE is used or exposed during the performance of
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.
a. Remove bottom cover from TI.
