1 = Elevation arm with antenna, here moved to the lowest position at elevation = +165°
2 = PCB holder set
3 = Turntable
4 = Distance approx. 30 mm from antenna to mounting plate (consider this azimuth as 0°)
5 = Distance approx. 10 mm from antenna to mounting plate, when azimuth is 45°
Risk of damaging absorbers
An expert user can assemble the PCB holder set using the centered (3a) or lateral (3b)
assembly holes, as labeled in Figure 7-8 .
If the lateral assembly holes (3b) are used and the holder set is attached with its
mounting plate pointing downward, it can collide with absorbers on the chamber's floor.
Such a collision can damage or destroy the absorbers, especially if the turntable
rotates at a low position.
To avoid this risk, the
expert user must select one of the following options for the
mounting plate:
●
Attaching the plate at a centered position, using the centered assembly holes (3a)
●
Attaching the plate pointing upward, using the lateral assembly holes (3b)
●
Leaving the turntable at a higher position, at least 1 cm above its lowest position
If you observe at least one of these points in your setup, the mounting plate of the
attached PCB holder set cannot collide with the absorbers.
7.5 Connecting a DUT
Familiarize yourself with residual risks and potentially dangerous situations.
See "Door of the chamber is heavy" on page 12 and "Operating the door" on page 14.
Various feedthroughs with interior and exterior connectors allow cable connections to
the DUT while it is tested in the chamber.
●
Every user can connect a DUT to cables available at the interior feedthrough con-
nectors inside the chamber.
Prerequisite: an
expert user has provided the required cables close to the DUT's
position.
●
Only an expert user is allowed to connect, disconnect or exchange cables at exte-
rior and interior feedthrough connectors
●
Only Rohde & Schwarz service personnel are allowed to mount, remove or
exchange feedthroughs
We recommend connecting your DUT to cables available in the chamber before you fix
the DUT on top of a holder. See
Chapter 7.4, "Placing a DUT in the Chamber" ,
on page 46.
The following DUT connection options are available inside the chamber:
●
Gigabit Ethernet (LAN) feedthrough [A121]
