(28) Reduce all outputs to minimum and disconnect equipment setup.
b. Adjustments. None.
12. Input 1
Sensitivity Test (26.5 GHz to 40 GHz) (Limited
deploy only)
a. Performance Check
(2) Set variable attenuator no. 1 to 0 dB.
(4) Adjust synthesized signal generator RF output controls and variable attenuator
No. 2 controls for a power meter no. 2 indication of -10 dBm.
(5) Slowly increase variable attenuator no. 1 attenuation until TI loses stable count.
(6) Slowly decrease variable attenuator no. 1 attenuation until TI just begins to
indicate a stable count.
(7) Add directional coupler actual coupling factor from correction chart to power
meter no. 2 indication and record sum.
(8) Subtract 0.5 dB (waveguide to coaxial adapter insertion loss (max)) from
variable attenuator no. 1 corrected value and record difference.
(9) Subtract difference recorded in (8) above from sum recorded in (7) above. If the
difference is not at least the minimum value listed in table 11, prepare a test report and
record actual sensitivity value for test frequency.
(10) Repeat technique of (2) through (9) above for the remaining frequencies listed in
