Rear Connectors
On its rear side the antenna coupler R&S
®
CMU-Z10 is equipped with two N connectors for input and
output of RF test signals, a sub-D connector for input and output of DC, AF or data signals, and an

Description of the
connectors
To test a mobile with the antenna coupler, the test instrument is connected to
the coupler via the
RF IN/OUT
connector:
RF IN/OUT
Standard bi-directional N female connector for antenna
coupler R&S
®
CMU-Z10
The following connectors can be used to connect the AF and RF circuit of a
mobile station that is tested in the shielded chamber but without using the
antenna coupler (to be used with option R&S
®
CMU-Z11).
DATA THROUGH
9-pin or 15-pin sub-D female connector for the DC, AF
or data signals of the MS under test
RF THROUGH
Bi-directional N female connector for the RF circuit of
the MS under test
The last RF connector is used to test
Bluetooth
devices in the shielded
chamber. It is available if option R&S
®
CMU-Z12,
Bluetooth
antenna, is fitted.
Otherwise the opening for the connector is closed with a metal plate.
USB feed through
The optional USB feed through (R&S
®
CMU-Z13) can be mounted instead of
either the DATA THROUGH connector or the Bluetooth antenna (see section
on p.
ff.).
Tip:
For the test of a USB data connection, the two possible connector
positions are equal. Just replace the connector that you do not
need for parallel tests.
Connection to test
instrument and DUT
R&S
®
CMU-Z10 is supplied with one RF cable with 2 N male connectors for
connection to a test instrument (e.g. R&S
®
CMU 200) via
RF IN/OUT, RF
THROUGH
or the
Bluetooth
connector.
The
DATA THROUGH
connector is for connection to a test instrument an
appropriate cable (not supplied with the shielding chamber).
