3. Tap the control element "New Angle TT" (turntable, labeled 4 in Figure 7-10 ).
An on-screen keypad is displayed.
4. Enter your target azimuth angle for the DUT turntable.
5. Tap "OK" to confirm your entry.
6. Press the [START] button on the left side of the front panel (labeled 1 in Fig-
ure 7-10 ).
The turntable inside the chamber moves, while the display continuously updates
the current azimuth angle.
7. Listen for unusual noise during operation.
8. If you notice unusual noise, proceed as described in Chapter 9.2.2, "Unusual Noise
from Positioner" , on page 73.
When the current angle has reached the target value, moving the DUT turntable is
completed. If necessary, you can open the chamber door.
For manually lifting or lowering the turntable, see "To move the DUT to a higher or
lower position" on page 47.
7.6.3 Combining the Elevation and Azimuth Movements
The elevation positioner can rotate from -20° to +165°; see Chapter 7.6.1, "Moving the
Elevation Positioner" , on page 60
At the same time, the azimuth turntable can rotate from -15° to +375°.
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.

The turntable is referenced; see "To reference the turntable" on page 57.
To move the azimuth turntable
1.
NOTICE! Risk of antenna collision with the turntable's crank. If the antenna arm is
at an elevation below 160° (maximum is 165°), rotation of the turntable can cause
the turntable's crank to collide with the antenna. Such a collision typically destroys
the antenna.
Make sure that the turntable's crank is removed; see
Figure 7-3 .
