26. High Power In
a. Performance Check
(1) Determine actual coupling value and insertion loss 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, and
the loss between primary input port and the output port with the auxiliary side arm port
terminated as shown in (a) through (j) 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.
Connect the 20 dB attenuator to the auxiliary port. Connect the measuring receiver to the
open end of the 20 dB attenuator. 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) Disconnect the measuring receiver and 20 dB attenuator from the auxillary port.
