26. High Power In
a. Performance Check
(1) Determine actual coupling value of directional coupler at 1090 and 1030 MHz for
use in paragraph (8) below by measuring the nominal loss between the primary input port
and the auxiliary side arm port, with the output port terminated as shown in (a) through
(h) below.
(a) Connect measuring receiver to signal generator output.
(b) Set signal generator output for 1090 MHz at 0 dBm.
(c) Set measuring receiver to measure frequency then measure tuned level.
(d) Set reference level on measuring receiver.
(e) Connect directional coupler input port to the signal generator output and
auxiliary output to measuring receiver. Ensure that the output and the reflected arm of the
directional coupler are terminated.
(f) Record the measuring receiver indication in table 41 for use in (8) below.
(g) Repeat technique in paragraphs (a) through (f) above at 1030 MHz at 0 dB.
(h) Repeat technique in paragraphs (a) through (f) above substituting the
directional coupler with the 20 dB attenuator at 1030 MHz and 1090 MHz for use in
(8) below.
