TB 9-6625-2080-24
b. Adjustments. No further adjustments can be made.
9. Output Power
a. Performance Check
NOTE
Most TI's require a matching attenuator to achieve the desired
power output. Matching attenuator must accompany TI when
submitted for calibration.
(1) Disconnect frequency difference meter from TI output jack.
(2) Connect true rms voltmeter to TI output jack using a 50 feed through
termination. True rms voltmeter will indicate between +13.0 and +14.1 dBm.
b. Adjustments. None.
10. Final Procedure
a. Deenergize and disconnect all equipment.
b. Annotate and affix DA label/form in accordance with TB 750-25.
CALIBRATION PROCESS FOR VECTRON LABORATORIES, MODEL 207-6192
11. Preliminary Instructions
a. The instructions outlined in paragraphs 11 and 12 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 results 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 these TI's.
d. Unless otherwise specified, all controls and control settings refer to the TI.
12. Equipment Setup
a. Connect dc power supply No. 1 positive output terminal to pin 4 of P1 on TI and
negative output terminal to pin 3 of P1 on TI.
b. Connect dc power supply No. 2 positive output terminal to pin 2 of P1 on TI and
negative output terminal to pin 3 of P1 on TI.
c. Adjust dc power supply No. 1 for a +24 Vdc output.
