DUT Alignment Lasers
The lasers are functional only when the door is open.
The [Laser] button on the front panel switches the alignment lasers on and off:

1 = Location of the [Laser] button
2 = Lasers "off"; button not lit and in unlatched position
3 = Lasers "on"; button lit and in latched (depressed) position
4 = View inside the chamber with alignment lasers switched on
You can use the laser crosshairs for repeatable positioning of your DUTs inside the
chamber; see
Chapter 7.4, "Placing a DUT in the Chamber"
Only an
is allowed to remove, mount or open the laser boxes (labeled
3
and 4
), and to align the lasers relative to the positioner axes.
4.3
Positioner
The 3D positioner in the chamber consists of an antenna elevation arm (labeled
1 in
) and a turntable (2). These two axes define 2 degrees of freedom of the
3D tilt-tilt positioner. The 3rd degree of freedom is the altitude at which you mount your
DUT on a DUT holder on the height-adjustable turntable.
For typical measurement scenarios, we recommend centering your DUT on the inter-
section of the two axes. Locking the third dimension to a fixed altitude reduces the
actively used degrees of freedom to two.
