These feedthroughs have interior and exterior connectors.
●
can connect a DUT to
interior
feedthrough connectors in the door,
hence connectors that face the chamber's inside.
●
is allowed to do the following:
–
Mount, remove or exchange feedthroughs
–
Connect, disconnect or exchange cables at exterior feedthrough connectors
If you connect your DUT to a feedthrough via RF cables, use shielded RF cables and a
torque wrench to tighten the connectors.
Risk of RF connector and cable damage / torque recommendations
Excessive tightening of coaxial RF connectors can damage the cables and connectors.
Too weak tightening causes inaccurate measurement results.
Always use a torque wrench suitable for the connector type and apply the torque speci-
fied in
application note 1MA99
, which is available on the internet at
. It provides additional information on the care and handling of RF con-
nectors.
For RF connectors, we recommend applying the following torque limits:
●
56
N
·
cm
for
SMA
connectors
●
90

for
PC
connectors (3.5

Never use a standard open-end wrench. We offer torque wrenches for various connec-
tors. For ordering information, see application note 1MA99.

Preparing for Shift End
Between production periods, do the following:
1. Open the chamber's door. See
Chapter 7.3.2, "Push-Button Door Operation"
Opening the door relaxes the gasket and maintains its RF shielding efficiency, see
2. Deactivate the chamber. See
Chapter 7.2, "Deactivating the Chamber"
