CALIBRATION PROCESS
6. Preliminary Instructions
a. The instructions outlined in paragraphs 6 and 7 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
name as listed in table 2.
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.
d. When indications specified in paragraphs 8 through 10 are not within tolerance,
perform the power supply check prior to making adjustments. After adjustments are made,
repeat paragraphs 8 through 10. Do not perform power supply check if all other
parameters are within tolerance.
e. Unless otherwise specified, all controls and control settings refer to the TI.
7. Equipment Setup
a. Set synthesized signal generator output for a 2 GHz signal at +6dBm.
b. Connect measuring receiver sensor module to the power reference output. Perform
sensor zero and calibration.
c. Set power meter MW-RANGE-DBM switch to 0.
d. Allow equipment to warm up for 1 hour.
e. Connect equipment as shown in figure 1.
f. Adjust synthesized signal generator level controls for a 0 dBm indication on
power meter.
