(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 Ω termination.
(20) Record receiver system indication in OUTPUT PORT 3 column of table 7.
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

NOTE
Perform (23) through (35) below for TI with frequency range
from 18 to 26.5 GHz.
OUTPUT controls for +3 dBm.
(25) Press signal generator No .2 frequency to 8650 MHz and adjust RF OUTPUT
controls for +8 dBm.
