(18) Disconnect TI from equipment setup and repeat (13) and (14) above.
(19) Connect TI into figure 4 equipment setup as listed in (a) through (c) below:
(a) INPUT PORT 1 to POINT A.
(b) OUTPUT PORT 3 to POINT B.
(c) OUTPUT PORT 2 to 50 : termination.
(20) Record receiver system indication in OUTPUT PORT 3 column of table 7.
(21) Adjust signal generator No. 1 and receiver system frequency controls to measure
and record insertion loss for OUTPUT PORT 3 for remaining frequencies listed in table 7.
Insertion loss will be equal to or less than the limits listed in Appendix D.
(22) Algebraically calculate the difference between the values recorded for OUTPUT
PORT 2 and OUTPUT PORT 3 columns of table 7. Record difference in OUTPUT PORT
TRACKING column in table 7. Output tracking will be within the limits specified in
NOTE
Perform (23) through (35) below for TI with frequency range
from 18 to 26.5 GHz.
(23) Connect equipment as shown in figure 5.
OUTPUT controls for +3 dBm.
controls for +8 dBm.
