NOTE
Ensure receiver system is in measurement mode.
(15) Record receiver system indication. Receiver system indication will be within the
nominal coupling (coupling variation) + ( frequency sensitivity) tolerances listed for TI in
(16) Establish a 0.00 dB reference on receiver system.
(17) Connect TI into figure 2 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 Ω termination.
(d) AUX (TEST) SIDEARM PORT (if any) to 50 Ω termination.
NOTE
Ensure receiver system is in measurement mode.
(18) Record receiver system indication. Receiver system indication will be greater
than or equal to the value listed for TI in directivity column, Appendix A.
(19) Repeat technique of (9) through (18) above for remaining test frequencies
recorded in 8 c above.
NOTE
Perform (20) through (32) below for TI with frequency range
from 26.5 to 40 GHz.
(20) Determine signal generator No. 2 (RF) frequency required for the desired
measurement by calculating the following equation: RF = test frequency in 8 c above/3.
EXAMPLE A:
If test frequency recorded in 8 c above is 27 GHz,
RF = 27 GHz/3
RF = 9 GHz
Signal generator No. 2 frequency would be adjusted to 9 GHz.
above and adjust RF OUTPUT to +3 dBm.
