TB 9-5985-314-24
NOTE
Use adapters as needed.
NOTE
Use waveguide-to-coaxial adapters when TI is waveguide.
(2) Connect POINT A to POINT B (fig. 1). Press receiver system frequency to test
frequency recorded in 8 c above and establish a 0.00 dB reference.
(3) Connect TI into figure 1 equipment setup as listed in (a) through (d) below:
(a) INPUT PORT to POINT A.
(b) SIDEARM PORT to POINT B.
(c) OUTPUT PORT to 50 : termination.
(d) AUX (TEST) SIDE ARM PORT (if any) to 50 : termination.
NOTE
Ensure receiver is in measurement mode.
(4) Record receiver system indication. Receiver system indication will be within the
nominal coupling value (coupling variation) + (frequency sensitivity) tolerances listed for
TI in Appendix A.
(5) Establish a 0.00 reference on receiver system.
(6) Connect TI into figure 1 equipment setup as listed in (a) through (d) below:
(a) OUTPUT PORT to POINT A.
(b) SIDEARM PORT to POINT B.
(c) INPUT PORT to 50 : termination.
(d) AUX (TEST) SIDEARM PORT (if any) to 50 : termination.
NOTE
Ensure receiver system is in measurement mode.
(7) Record receiver system indication. Receiver system indication will be greater
than or equal to the value listed in TI directivity column, Appendix A.
(8) Repeat technique of (1) through (7) above for remaining test frequencies
recorded in 8 c above.
NOTE
Perform (9) through (19) below for TI test frequencies from 18
to 26.5 GHz.
