2.4 Safety Instructions for Unpacking, Transport and Mounting
Risk of contusion due to heavy moving parts
For transportation, the RF Shielded Box is originally contained in a special transport
protection packaging. After unpacking, there is no additional protection to prevent
opening of the drawer. Especially when the chamber is tilt, the drawer can slide open
unintentionally. This movement can cause personal injuries, especially contusion.
To avoid this risk, make sure that the RF Shielded Box is always in a horizontal position.

R&S®TS7124M
Specific Safety Instructions
Safety Instructions for Unpacking, Transport and Mounting
Figure 2-1: Tipping hazard with the drawer sliding open in an uncontrolled manner
An additional safety measure is implemented by a metal safety latch next to the top left
corner of the front door. This latch prevents unintentional opening of the drawer:
Figure 2-2: Metal safety latch
When you remove this safety latch and especially when the chamber is tilt, the drawer
can slide open unintentionally. This movement can cause personal injuries, especially
contusion.
To avoid this risk, leave the safety latch mounted until the chamber is securely mounted.
Never use the handle for lifting the RF Shielded Box.
Packaging material
To be prepared for later transportation or shipping of the RF Shielded Box, retain the
original special transport protection packaging and the safety latch (Figure 2-2). If the
RF Shielded Box has to be transported or shipped again, attach the safety latch and
repack the chamber in its original packaging, which keeps the drawer closed.
If the original packaging material and the metal safety latch are no longer available,
secure the drawer against unintentional opening in an appropriate way.
Risk of injury due to heavy weight
12User Manual 1525.5394.02 ─ 04
R&S®TS7124M
Specific Safety Instructions
Safety Instructions for Operation
Handling the heavy chamber (e.g. lifting or transporting it) may result in personal injury.
In order to prevent this, at least two persons are required for handling the RF Shielded
Box. Never use the handle for lifting the RF Shielded Box.
The RF Shielded Box must be mounted by fixing it horizontally to a stable bench/
support with screws and four brackets, see Chapter 6.1, "Setup", on page 68.
Risk of injury due to unstable mounting
The support (bench, table, rack, or the like) onto which the RF Shielded Box is to be
mounted, has to be sufficiently stable to bear the chamber's weight and to withstand
the door's momentum during operation. The screws with which the mounting brackets
(see Chapter 6.1.3, "Positioning the Chamber", on page 70) are fixed to the support,
have to be suitable to hold a tight grip in the support's material and strong enough to
withstand a dynamic long-term load. If the support or the screws should fail, the chamber may become destabilized and eventually tip out of place. This could cause personal injuries, especially contusion.
To avoid this risk, make sure that the RF Shielded Box is securely mounted on a stable
support.
2.5 Safety Instructions for Operation
Risk of injury due to door operation
The heavy RF Shielded Box features a solid metal door that can be manually opened
and closed. The heavy weight is required to achieve high levels of electromagnetic
shielding. If the door is closed without caution, this implies some risk of injury for the
operators.

R&S®TS7124M
Specific Safety Instructions
Safety Instructions for Operation
Figure 2-3: Mechanical hazards involved with the moving front door / drawer (left) as well as with the
guide rail. The red arrow indicates the risk of a tipping chamber if it is opened without
being fixed to a stable support
The inertia of the door, if it is closed fast, may be sufficient to cause personal injury,
especially contusion of hands and fingers. To avoid this risk of "fast" contusion, always
keep away from the gap between the chamber's door and wall, while closing the door.
Additionally, there is a risk of "slow" contusion between door and chamber, while locking the door by its handle. To reduce this risk, the locking mechanism is only engaged
if the door is almost closed: Once the locking hooks of the handle are caught in their
counterpart in the chamber wall, the gap between door and chamber is too small to
insert fingers.
However, any mechanism could fail. To avoid potential risks, keep away from the gap
between the door and the chamber, when the door is about to be closed. Also, do not
touch the movable guide rails.
Risk of contusion due to heavy moving parts
Both the chamber and the door are heavy. The weight and the leverage effect of the
open drawer is sufficient to destabilize the whole chamber and make it tilt forward. This
risk is enhanced by the typical situation of the opened door protruding over the edge of
a table or support.
The risk of tilting is especially high during the installation phase, before the RF Shielded Box is securely mounted in a horizontal position (see Figure 2-1). With neither the
special transport protection packaging nor the handle keeping the door closed, the
14User Manual 1525.5394.02 ─ 04
R&S®TS7124M
Specific Safety Instructions
Safety Instructions for Maintenance
combination of a tilting movement of the whole chamber and the drawer sliding open
unintentionally could enhance the risk.
Any of these instability conditions might lead to personal injury, especially contusion.
To avoid this risk, make sure that prior to operation the chamber is securely mounted to
a stable support (see Chapter 6.1, "Setup", on page 68).
Risk of injury in case of malfunction
If the RF Shielded Box is operated without being in proper working order, malfunctions
could lead to unpredictable events.
To avoid risks in the event of a malfunction,
●
immediately take the chamber out of operation,
●
report the malfunction to the responsible department,
●
eliminate any faults before work is continued.
Other Safety Instructions
Persons not trained in handling the RF Shielded Box must be kept out of the range of
operation, as they may not know about all potential hazards of injury.
Observe the site's internal instructions and ensure that the area of operation is always
clear and clean. All areas for operation and maintenance must be kept easy to access.
2.6 Safety Instructions for Maintenance
Risk of injury in case of uninformed maintenance
If maintenance tasks are performed by untrained personnel, this may lead to risks of
personal injury and damage to the equipment.
To avoid these risks, maintenance tasks may only be performed by trained personnel.
Risk of damaging mechanical parts
To avoid malfunction and damage to mechanical parts,especially the drawer guide rails
(3 in Figure 4-1), do not apply liquid cleaning agents such as contact spray.

3 System Overview and Usage
System Overview and Usage
The RF Shielded Box is an adaptation platform, built for the testing of electronic devices with RF interfaces, especially
●
Mobile phones
●
PDAs
●
Radio keys
●
WLAN / Wi-Fi modules
●
Bluetooth® modules, etc.
The R&S TS7124M is used in production, for service, repairs and other applications.
For radiation testing, the DUT is inserted into the chamber by means of a drawer,
which is closed by a tightly sealing door. Antennas installed on the inside of the RF
Shielded Box then interact with the DUT by emitting or receiving electromagnetic radiation. The antennas can be placed and oriented in a customer-specific geometrical
arrangement.
Submitting a DUT to conducted instead of radiated RF signals via feedthroughs for RF
cables (or guiding conducted RF signals away from the DUT) can be applied as an
alternative or supplement to antennas.
The susceptibility and behavior of the DUT can be monitored via USB or D-Sub feedthrough connections, which can also be used to send control commands to the DUT.
For this purpose, it is recommended to use version 1525.8564.12 of the RF Shielded
Box with two feedthrough ports in the front door.
To minimize redundancy in the manual, most of the descriptions refer to this RF Shielded Box version. However, the descriptions apply in a similar way to the basic version
1525.8564.02 that does not feature port openings for front feedthroughs.
Control signals and measured signals may typically be managed by a customer-specific test system. This could be designed to handle one individual RF Shielded Box, or
several, or even a large number of chambers. The test system may typically comprise:
●
Signal generators
●
RF cables
●
Signal switch boxes
●
Signal analyzers
●
Data recorders
●
A computer-based control system
●
Racks for mounting multiple RF Shielded Boxes

Hardware Description
Hardware Overview
The front drawer (1) of the RF Shielded Box is used for insertion of the DUT. The
drawer guide rails (3, one on each side) support the drawer when it is manually opened
and closed by means of the handle (4).
The polymeric gasket (2) features a conductive chromated aluminum surface to prevent leakage of RF radiation out of the chamber, and into it. Avoid touching or soiling

throughs (here covered with two metal plates)
12 = Two front screw holes for mounting brackets (included in shipment)
There are two handles (10) on each side of the RF Shielded Box. If the chamber is lifted or transported (prior to mounting), at least two persons are required for handling it.
Two screw holes (12) at the lower end (and two more at the rear side) serve for fixing
the chamber to a stable support by means of special brackets (see Chapter 6.1,
"Setup", on page 68).
Various filtered control feedthroughs and RF feedthroughs are available (see Chap-
ter 5, "Accessories", on page 23). They can be mounted in the front door after
removing one or both of the metal plates (11) that cover the openings. The interfaces in
the feedthroughs can be used for controlling and monitoring a DUT while it is tested
inside the closed chamber, or for feeding RF signals through the door to or from the
DUT. As the three openings on the rear side of the RF Shielded Box (see Figure 4-4)
are numbered 1 to 3, the numbering convention for the two openings on the front side
of the chamber is 4 to 5 from left to right.
In Figure 4-3, a few small threaded holes on the outside of the front door can be seen
on the lower left side. These are no through holes, the chamber's RF shielding is not
impaired. They are intended to screw on a fixture that guides cables from the front
feedthroughs to an optional energy chain.

The top cover (13) of the RF Shielded Box is fixed by six quick clamps (15). It can be
removed for antenna configuration and service issues (see Chapter 7.1, "Opening and
Closing the Top Cover", on page 78).
The warranty seal (14) indicates that the R&S TS7124M is in its original delivery state,
with a shielding effectiveness as specified in the data sheet. For configuration of the
interior of the RF Shielded Box, the top cover has to be opened and the seal has to be
broken. After closing the cover it is in the user's responsibility to restore a good shielding effectiveness. To do so, proceed as described in Chapter 7.1.3, "Adjusting the
Locking Force of the Cover", on page 83.
At the rear side of the RF Shielded Box, there are four shielded RF feedthrough connectors (16, see Chapter 4.1.2.1, "Rear Feedthroughs", on page 21). These can be
used, e.g., for up to four individual antennas (see Chapter 5, "Accessories",
on page 23), or for up to two antennas with dual polarization (see Chapter 5.20,
"Cross-Polarized Vivaldi Antenna R&S TS-F24-V3", on page 50).

Hardware Description
Hardware Overview
Three metal cover plates (17) at the rear side of the chamber can optionally be
replaced by additional filtered control feedthroughs or RF feedthroughs (see Chapter 5,
"Accessories", on page 23). For example, with each Twin N-SMA Feedthrough
R&S TS-F24FN1 providing two additional RF feedthroughs (from SMA to N connector),
a total of ten individual antennas can be connected inside the RF Shielded Box. For
more details, see Chapter 4.1.2.1, "Rear Feedthroughs", on page 21.
Two screw holes (19) at the lower end (and two more at the front side) serve for fixing
the chamber to a stable support by means of special brackets (see Chapter 6.1,
"Setup", on page 68).

Risk of reduced shielding efficiency
If the metal cover plates are replaced by feedthrough connectors, care must be taken
to restore the chamber’s shielding efficiency. For correct installation, see mounting
instructions for feedthrough connectors. If a feedthrough is installed incorrectly, the
shielding efficiency may deteriorate dramatically.

5.1 Basic Absorber R&S TS-F24ABS
The R&S TS-F24ABS (1525.8593.02) is the basic absorber material placed on the
inside of all walls of the chamber, including the door, the top cover and the ground.
Optionally, the RF Shielded Box can be ordered without these absorbers, but for most
applications (and for this user manual) it is assumed that it would typically be installed
in the chamber.

The DUT holder tray is not a serviceable part. If it is defective or not working correctly,
it has to be replaced.
5.3 Half Antenna Ring R&S TS-F24-AH1
The R&S TS-F24-AH1 (Rohde & Schwarz order number 1525.8887.02) is an optional
antenna mounting structure to be placed inside the RF Shielded Box, in the upper half
of it. Hence, this antenna ring is called "half antenna ring" to differentiate it from the Full
Antenna Ring R&S TS-F24-AR that fills the whole chamber.
It would be possible to place two half antenna rings inside the R&S TS7124M, but this
setup is not recommended, since it is not stable. If necessary, use the full antenna ring
instead.
