7.6.1 Moving the Elevation Positioner
The elevation positioner is the antenna arm. It can rotate up to -20° to the front and the
following maximum angle to the rear:
●
If you set the NCD controller manually, the maximum rotation to the rear is limited
to
+160° .
●
If you use the R&S AMS32 software for setting the angle, the elevation arm can
rotate down to +165° to the rear. Before making this setting, make sure that you
have removed the turntable's crank. See Figure 7-3 .
Prerequisites:
●
The chamber is set up as described in Chapter 6, "Installation and Commission-
ing" , on page 35
●
The chamber is activated; see Chapter 7.1, "Activating the Chamber" , on page 43.
●
The NCD controller is activated; see "To activate the controller" on page 57.
To move the elevation positioner arm
1.
NOTICE! Risk of antenna collision with the turntable's crank. If the antenna arm
moves below 160° elevation (maximum is 165°, see below), the antenna mounted
on the arm can collide with the turntable's crank. Such a collision typically destroys
the antenna.
Make sure that the turntable's crank is removed; see
Figure 7-3 .
2. Close the chamber door as described in Chapter 7.3.4, "Closing the Door" ,
on page 46.
Closing the door releases the lower interlock ( Figure 4-7 ); the positioners are no
longer prevented from moving.
Release of the interlock is also indicated in the display of the NCD controller, i.e.
the interlock symbol disappears; see
Figure 4-8 .
3. Tap the control element "New Angle AB1" (antenna boom, labeled 3 in Fig-
ure 7-10 ).
An on-screen keypad is displayed.
4. Enter the target elevation angle for the antenna positioner arm.
5. Tap "OK" to confirm the entry.
