Introduction
Regulatory information
This instructions handbook addresses every user of the chamber (also referred to as
the product). To use the chamber safely, first read and understand this entire handbook. If you are unsure about a topic, ask your supervisor or contact Rohde & Schwarz
customer support.
The instructions handbook helps you to use the chamber safely and efficiently during
its entire lifecycle; installation, operation, maintenance and disabling. If you are only
involved in one part of the lifecycle, focus on the chapter about that topic. But always
get a deep understanding of the safety aspects described in Chapter 2, "Safety",
on page 10 before starting.
The chapter titles give a clear idea of the lifecycle stage and the tasks described. For
example, if you are an operator, most activities intended for you are described in Chap-
ter 7, "Operation", on page 37. If tasks are restricted to certain roles, these roles are
mentioned at the beginning of the chapter that describes the tasks. The roles are
explained in the glossary.
Abbreviations and frequently used terms are explained in the glossary at the end of
this handbook.

2.1 Intended use
The chamber is intended for radiation testing of electronic components and devices in
industrial, administrative, and laboratory environments, see Chapter 6.1, "Choosing the
operating site", on page 24. Use the chamber only for its designated purpose, as
described in this handbook. Observe the operating conditions and performance limits
stated in the data sheet. If you are unsure about the appropriate use, contact
Rohde & Schwarz customer support.
2.2 Residual risks
Despite the inherent safe design measures, safeguarding and complementary protective measures adopted, residual risks remain because of the following facts.
Chamber is heavy
The weight of the chamber without accessories and antenna cage is approximately
60 kg. In total, the chamber can weigh up to roughly 70 kg. If the chamber drops on a
person, it can cause severe injuries, even death.
10Instructions Handbook 1179.2902.02 ─ 02
R&S®CMQ200
Safety
Potentially dangerous situations
Door of the chamber is heavy
The center of gravity moves with the door when you open it. If the chamber topples, it
can cause severe injuries, even death.
Moving door
Applies only to a chamber with an electrically or pneumatically operated door.
When you trigger the closing of the door, the door starts closing with reduced force. A
built-in soft-close mechanism prevents the door from closing with full force as long as
the gap is large enough to put a finger in it, maximum 8 mm. But if this safety mechanism fails, and the door closes with full force with a finger between the door and door
frame, the finger is crushed. Even the loss of the limb is possible.
The safety mechanism is described in detail in Chapter 3.2, "Automatic emergency
deactivation", on page 15.
Electrically powered
The risks, requirements for installation and safety measures are described in "Connect-
ing to power" on page 12.
Pneumatically operated door
Applies only to a chamber with a pneumatically operated door.
Supply the compressed air for the pneumatic system at a pressure of 6 bar. If the pres-
sure exceeds the limit of 7 bar, the chamber operates under unspecified conditions.
When operating the door at > 7 bar, uncontrolled situations can occur, causing injuries
like crushed fingers. See Chapter 6.4, "Connecting compressed air", on page 28.
2.3 Potentially dangerous situations
Potentially dangerous situations can occur during the following activities.
Transport
Wear appropriate protective clothing that complies with your local rules and regulations. If you are unsure of which equipment to use, ask your safety inspector. For
example, gloves help to keep a tight grip on the handles when carrying the chamber.
Without gloves, you have less friction and your grip can slip if your hand is oily or wet.
As a result, the chamber can drop and crush your foot or someone else's. Therefore,
always wear safety shoes with toe cap when moving the chamber.
Always secure the door when moving the chamber, even if it is only for a short distance. See Chapter 5.3, "Securing", on page 22 for details on how to do it properly. If
the door is not secured and opens while you are carrying the chamber, the center of
gravity shifts. As a result, one of the carrying persons suddenly has to bear a much
larger portion of the weight. When the sliding door hits its end position, the sudden stop
results in a powerful thrust. If the person cannot manage the extra weight or loses grip
of the handle, the chamber can drop and cause severe injuries, even death.
11Instructions Handbook 1179.2902.02 ─ 02
R&S®CMQ200
Safety
Potentially dangerous situations
The chamber is heavy. Do not move, lift or carry the chamber by yourself. A single person can only carry a maximum of 18 kg safely depending on age, gender and physical
condition. So at least 4 people are required. With fewer people, you risk injuries, ranging from back injuries from too heavy lifting to severe injuries like contusions or limb
loss if the chamber is dropped.
If you suffer from medical problems such as spinal and back disorder, or if your physical state is not compatible with lifting a heavy chamber, do not participate in carrying it.
Use the handles to move or carry the chamber. See Chapter 4, "Machine overview",
on page 17 to see where the handles are located.
To move the chamber safely, you can use lifting or transporting equipment such as lift
trucks and forklifts. Follow the instructions provided by the equipment manufacturer.
A chamber with optional height extension R&S CMQ-B703 (Figure 4-3) is significantly
more heavy, and the center of gravity is higher. Never lift, carry or transport a chamber
with height extension, because it can tip over easily, leading to an increased risk of
injuries. Also, the handles are not suited for the increased weight. To enable separate
transport of the height extension and the base chamber, let an expert user or
Rohde & Schwarz service personnel uninstall the height extension from the chamber.
For detailed instructions, see Chapter 5.1, "Lifting and carrying", on page 21.
Setting up
Place the chamber on a sufficiently sturdy support that can bear the weight of the
chamber. Secure the support against toppling over, for example by fixing it to the floor.
Observe the specifications of the manufacturer. Always place the chamber on a flat
and level surface with the bottom of the chamber facing down. If the support is not
sturdy enough, it can collapse. If the support is not level, the chamber can slide and
drop from the support. In both cases, severe injuries are possible, even death.
When the chamber is positioned, secure the chamber as shown in Figure 6-3. If you do
not secure the chamber, the chamber can topple when opening the door, as described
in "Door of the chamber is heavy" on page 11.
Set up a restricted area that only trained personnel are allowed to enter. In the restricted area, mark the space on the floor that is required for fully opening the door.
Route cables carefully and ensure that nobody can trip over loose cables.
For detailed instructions, see Chapter 6.3, "Mounting the chamber", on page 26 and
Chapter 6.7, "Defining zones of restricted access", on page 34.
Connecting to power
The chamber runs on 24 V DC supplied by an external power supply unit that is included in the delivery. The power supply unit has overvoltage category II. Connect it to a
fixed installation used to supply energy-consuming equipment such as household
appliances and similar loads. Be aware of electrical risks, such as electric shock, fire,
personal injury or even death.
12Instructions Handbook 1179.2902.02 ─ 02
R&S®CMQ200
Warning messages in this handbook
Take the following measures for your safety:
●
Before connecting the power supply unit to a power source (your mains grid),
ensure that this source matches the voltage and frequency [INPUT] range indicated on the power supply unit.
●
Only use the external power supply unit that is delivered with the chamber. It complies with country-specific safety requirements.
Only insert its plug into an outlet with protective conductor terminal.
●
Only connect the power supply unit to a power source that is protected by a 16 A
circuit breaker (branch protection).
●
Ensure that you can disconnect the power supply unit from the power source at
any time. Pull the power plug to disconnect the chamber. The power plug must be
easily accessible.
●
Install an easily accessible panic button (power-off switch, not included in the delivery) for interrupting power supply to the chamber.
Operating the door
Applies only to a chamber with an electrically or pneumatically operated door.
Safety
You can open and close the door by pressing a button while standing next to the chamber. Also, you can operate the door remotely. In either case, ensure that nobody has
their fingers on the guide rails of the door or between the door and door frame. Establish safety rules as the following:
●
During manual door operation, only the person pressing the button is allowed in the
restricted area. After pressing the button, the person steps back from the chamber.
●
During remote door operation, nobody is allowed in the restricted area.
●
During operation, hands are kept out of the chamber, except for exchanging a
DUT. During DUT exchange, nobody is allowed to operate the door.
Use the chamber as it is designed. Never tamper with its safety installations.
For detailed instructions, see Chapter 7.3, "Operating the door", on page 39.
Maintenance
Carry out the maintenance tasks as required. You thus ensure flawless functionality of
the chamber and, in consequence, the safety of everyone working with the chamber.
For detailed instructions, see Chapter 9, "Inspection and maintenance", on page 58.
Cleaning
See Chapter 9.4.4, "Cleaning the chamber", on page 62 and Chapter 9.4.5, "Cleaning
the gasket", on page 62.

3 Emergencies
3.1 Emergency stop
Emergencies
Automatic emergency deactivation
Applies only to a chamber with an electrically or pneumatically operated door.
Possible emergencies can result from a failure of the soft-close mechanism that stops
the door, if an obstacle prevents closing, see Automatic emergency deactivation.
But if the soft-close mechanism fails and you have your hands in the way of the closing
door, your hands can get caught between the door and the chamber's frame. In this
case, use the Emergency stop.
Applies only to a chamber with an electrically or pneumatically operated door.
To stop the chamber's door quickly at any time, interrupt the electric power supply.
To interrupt the electric power supply
1. Hit the panic button that switches power off.
See "Prerequisites for power connection" on page 31.
2. If no panic button is installed:
● Pull the power supply unit out of the grid power socket.
● Or pull the DC plug out of its socket on the rear side of the chamber.
See Figure 7-1.
Interrupting the electric power supply has the following effects:
●
The door movement stops immediately.
●
The door's LED is off.
●
If the door is operated pneumatically, the pneumatic system is depressurized and
the door is left forceless. You can push it open or close manually against a merely
frictional resistance.
●
If the door is operated electrically, you can move it manually only with great force.
To reactivate the chamber, proceed as described in Chapter 7.1, "Activating the cham-
ber", on page 37.
3.2 Automatic emergency deactivation
Applies only to a chamber with an electrically or pneumatically operated door.
During normal operation, the door closes tightly with high force to provide sufficient
shielding effectiveness. To prevent injury due to this forced closing, the door's soft-
close mechanism moves with a lower force until it is almost closed: maximum 8 mm
15Instructions Handbook 1179.2902.02 ─ 02
R&S®CMQ200
3.2.1 Electrically operated door
Emergencies
Automatic emergency deactivation
gap remaining. The door mechanism switches to high force to close the final 8 mm gap
only if no obstacle stops this low-force closing.
Applies to a chamber with the R&S CMQ-B20B or R&S CMQ-B20C option.
The door movement stops automatically if:
●
Something larger than 8 mm gets caught between the chamber and the door.
●
The door is pulled with force.
This emergency deactivation mechanism relaxes the door by approximately 1 cm and
is accompanied by a short clacking sound. The LED starts flashing red to indicate a
door error, but frictional forces resist against moving the door manually.
To reactivate the chamber
1. Remove any obstacle out of the door's way.
2. Push the door slightly towards closing until it makes a clacking sound.
3. Continue as described in Chapter 7.3.6, "Procedure when LED is flashing",
on page 44.
3.2.2 Pneumatically operated door
Applies to a chamber with the R&S CMQ-B21A or R&S CMQ-B21C option.
If the door does not open or close within the predefined timeout period of 8 s, the con-
trol system switches to "ERROR" mode.
The LED starts flashing red to indicate the door error, and the pneumatic system is
depressurized automatically, leaving the door forceless. This deactivation prevents a
situation in which the operator's hands are caught between the chamber and the door
and the operator cannot reach for the door's open/close button.
To reactivate the chamber
1. Remove any obstacle out of the door's way.
2. Continue as described in Chapter 7.3.6, "Procedure when LED is flashing",
on page 44.
You can verify proper functioning of the door's soft-close mechanism as described in
Chapter 6.6, "Testing safety systems", on page 33.

Three openings (4), numbered A11 to A13, are provided for optional RF-filtered feedthroughs. Openings that are not used are covered with blank metal plates.
Front feedthroughs allow feeding control or RF signals or electric power through the
wall to a DUT in the chamber, see Chapter 7.5, "Connecting a DUT", on page 48.
Only an expert user is allowed to exchange the metal plates or feedthroughs, and to
connect, disconnect or exchange cables at the feedthroughs.
The door's open/close button (6) triggers the opening and closing of a chamber with
automatically operated door. The LED below this button indicates the door status; see
Chapter 7.3, "Operating the door", on page 39.

Performance-enhancing options
The top cover (1) of the chamber is fixed by 16 screws. Only an expert user is allowed
to open it.
In the rear wall, 10 openings (2), numbered A21 to A25 and A31 to A35, are provided
for optional RF-filtered feedthroughs. Openings that are not used are covered with
blank metal plates.
Rear feedthroughs allow feeding control or RF signals through the wall to antennas or
to other equipment in the chamber. Only an expert user is allowed to exchange the
metal plates or feedthroughs, and to connect, disconnect or exchange cables at the
feedthroughs.
The carrier plate (3) between the feedthroughs (2) is prepared for holding remote radio
heads (RRH). This setup allows short cable lengths from the RRHs to the antennas
inside the chamber.
The lower compartment of the chamber, which contains the electric or pneumatic door
mechanism, provides the following:
●
Six D-Sub 9 control connectors (4) for six R&S CMQ-B744A RF Connection Kit 4
options: integrated RF switches (SP6T relays).
●
Two additional feedthrough openings, covered with metal plates.
●
The supply and control panel (5) with connectors for power, control and compressed air; see Chapter 6.5, "Connecting to control and power", on page 30.
4.3 Performance-enhancing options
A pneumatically or manually operated chamber with option R&S CMQ-B221H for
higher shielding efficiency (order no. 1540.4014.04) has a higher door with two builtin electromagnets in the top corners. These magnets can pull the door close with
strong force, reducing the door gap and enhancing the RF sealing of the door.
A chamber version with manual door operation, R&S CMQ-B22C (left in Figure 4-3),
has a different front panel with a handle.
A chamber version with optional height extension, R&S CMQ-B703A/B/C (right in Fig-
ure 4-3), has a hood on top of the chamber. The hood has the same dimensions as the
chamber below.

Correct lifting and carrying
WARNING! The door of the chamber is heavy and can move. See "Door of the
1.
chamber is heavy" on page 11 and "Moving door" on page 11.
If the door is not secured against opening, secure it as described in Chapter 5.3,
"Securing", on page 22.
WARNING! Chamber is heavy. See "Transport" on page 11 and "Chamber is
2.
heavy" on page 10.
For short distances, lift a single chamber at its handles with at least 4 people.
Figure 4-1 shows the handles.
Note: Never lift, carry or transport a chamber with optional height extension
R&S CMQ-B703 (Figure 4-3), because it can tip over easily, and the handles are
not suited for the increased weight. To enable separate transport of the height
extension and the base chamber, let an expert user or Rohde & Schwarz service
personnel uninstall the height extension from the base chamber.
3. For longer distances or if one or more chambers are on a pallet, use lifting or trans-
porting equipment such as lift trucks and forklifts.
Follow the instructions provided by the equipment manufacturer.
See also Chapter 5.4, "Transport", on page 23.
5.2 Packing
Use the original packaging material. It consists of antistatic wrap for electrostatic protection and packing material designed for the product.
If you do not have the original packaging, use similar materials that provide the same
level of protection.
The original packaging material also keeps the door closed. If this material is no longer
available, secure the door against opening and use similar materials that provide the

5.3 Securing
Transportation, handling and storage
Securing
same level of protection. Use sufficient padding to prevent unintentional mechanical
effects during transportation.
When delivered, the chamber is contained in a special transport protection packaging
that prevents the door from opening.
After unpacking, there is no additional protection to prevent unintentional movement of
the door.
If you tilt the chamber, for example when you lift it, the door can slide open or close
unintentionally, especially in chambers with pneumatic door operation. Read the consequences in "Transport" on page 11.
Figure 5-1: Do not lift with unsecured door: risk of uncontrolled door movement
To avoid this risk, close the chamber's door and secure it against opening, before you
lift the chamber and until the chamber is securely mounted.
To secure the door
1. Firmly tie a rope from a handle on the chamber's left side to a handle on the right.
Use a rope that is strong enough to hold a weight of 100 N (10 kg). The rope is not
included in the delivery.
2. Lift the chamber as described in Chapter 5.1, "Lifting and carrying", on page 21.
Note: If you proceed with mounting and operating the chamber, we recommend
that after mounting, you remove the rope or any item that secures the door.
Removing it avoids unintentional interaction with the door during operation.
