 7–12  Commissioning the RT

RT installation

Current voltage level with
oscillation up to 4.1 V

. (The

reading intermittently peaks
at the current voltage level
for 2 seconds and then
rises to 4.1 V for 1 second.)

HT not acquired

HT acquisition has not
occurred. Continue
pointing the antenna.

3.9 V to 4.1 V with no
oscillation

Correct HT
acquired

HT acquisition has
occurred but you must
install a mechanical
attenuator before
continuing with the
installation, refer to
section 6.8.

Current voltage level with
oscillation to 0 V. 

(The

reading intermittently peaks
at the current voltage level
for 2 seconds and then
drops to 0 V for 1 second.)

Wrong HT
acquired

RT has been denied
acquisition by the wrong
HT. You must follow the
procedures listed in
Repointing the RT
antenna below before
proceeding.

Follow the steps below to repoint the RT antenna only if the ODU
has acquired the wrong HT.

(If you have successfully pointed the antenna—with a steady
voltmeter reading between 0.2 volts and 3.9 volts—you do not
need to follow steps 1 and 2 below; go on to section 7.5.)

1.

Repeat steps 7 through 12 (voltmeter pointing and final
adjustments).

2.

If you cannot obtain the correct voltmeter readings because
the antenna is grossly mispointed, you may have to  repeat
the azimuth and elevation adjustment procedures explained
in sections 6.6 and 6.7 (respectively).

If you encounter problems in pointing the antenna that are not
addressed above, refer to chapter 9. See the chart titled
Troubleshooting: RT antenna pointing.
