INSTALLATION CHECK
1. Overview
A. General
(1) The procedures that follow are designed to check for the satisfactory installation of
the HS--600 HSD system prior to LRU installation.
2. Installation Checkout
A. General
(1) The HSD system aircraft installation checkout should include, but is not limited to, the
following steps:
•
Cable loss checks
•
Power checks
•
RF checks.
B. Cable Loss Checks
(1) HS--600 HSU to HPA Path Loss
(a) Measure the total cable and connector losses between the HSU TX output
(BP13) to the HPA RF input (TP1C).
(b) If necessary, install an attenuator to achieve a total loss of 19--21 dB.
(2) HPA to Antenna Loss
(a) Measure the total loss between the HS--600 HPA RF output (MP1C) to the
antenna RF port (J2).
(b) Enter this value into parameter No. 5 through the HS--600 maintenance port. Do
no change any other parameters. Do no forget to save the changes.
(c) Assuming that this value is equal to the SDU HPA to antenna loss, enter the
value through the SDU CMT using the keystrokes listed below. If the loss is more
than 1 dB different from the HS--600 HPA to antenna loss, measure the loss first
before entering the value.
(d) From the SDU main menu, make the following selections:
•
F) Physical Layer Menu
•
C) Power Control Menu
•
D) Manual Power Control Menu
•
B) HGA HPA to Antenna Loss.
(e) Enter the loss value. If greater than 5 dB, enter 5 dB.
