Safety instructions
These requirements apply to both the AXRF RF Subsystem and the AutoCal Unit, unless otherwise
specified.
For user safety, read and follow all instructions, WARNINGS, CAUTIONS, and Notes marked in this
manual and on the associated instrument before handling or operating the instrument.
Read these safety instructions carefully.
Keep this manual for future reference.
Read the specifications section of this manual for information about the operating environment of
the instrument.
When installing/mounting or uninstalling/removing an instrument:
turn off power and unplug any power cords/cables.
To avoid electrical shock and/or damage to the instrument:
keep the instrument away from water or liquid sources;
keep the instrument away from high heat or high humidity;
keep the instrument properly ventilated (do not block or cover ventilation openings);
make sure to use recommended voltage and power source settings;
always install and operate the instrument near an easily accessible electrical socket-outlet;
secure the power cord (do not place any object on/over the power cord);
only install/attach and operate the instrument on stable surfaces and/or recommended
mountings;
if the instrument is not to be used for long periods, turn it off and unplug it from its power source.
Never attempt to repair an instrument. Instruments should only be serviced by qualified personnel.
An instrument must be serviced by authorized technicians when:
the power cord or plug is damaged;
liquid has penetrated the instrument;
it has been exposed to high humidity/moisture;
it is not functioning or does not function according to the user manual;
it has been dropped and/or damaged;
it has an obvious sign of breakage.
Invalid cal data/damage to modules
Do not remove any of the installed PXI modules. Removing a module invalidates the system
calibration data supplied with the AXRF RF Subsystem, and may damage the module.

Precautions
These terms have specific meanings in this manual:
information to prevent personal injury.
information to prevent damage to the equipment.
important general information.
Hazard symbols
The meaning of hazard symbols appearing on the equipment and in the documentation is as follows:
Symbol Description
Refer to the operating manual when this symbol is marked on the
equipment. Familiarize yourself with the nature of the hazard and the
actions that may have to be taken.
Dangerous voltage
Toxic hazard
Hot surface
Suitability for use
This equipment has been designed and manufactured by Cobham to generate low-power RF signals
for testing radio communications apparatus and to digitize and provide spectrum analysis of RF
signals.
If the equipment is not used in a manner specified by Cobham, or if it is damaged, the protection
provided by the equipment may be impaired.
Cobham has no control over the use of this equipment and cannot be held responsible for events
arising from its use other than for its intended purpose.
General conditions of use
This product is designed and tested to comply with the requirements of BS EN 61010-1 ‘Safety
requirements for electrical equipment for measurement, control and laboratory use’, for Class III
equipment and is for use in a pollution degree 2 environment. The equipment is designed to operate
from an installation category II supply.
Equipment should be protected from the ingress of liquids and precipitation such as rain, snow, etc.
When moving the equipment from a cold to a hot environment, it is important to allow the
temperature of the equipment to stabilize before it is connected to the supply to avoid
condensation forming. The equipment must only be operated within the environmental conditions
specified in the data sheet, otherwise the protection provided by the equipment may be impaired.
This product is not approved for use in hazardous atmospheres or medical applications or safety-
critical applications.
The enclosure of the host PXI chassis should meet the enclosure requirements of BS EN 61010-1, in
order to provide an appropriate fire enclosure for the product.

Safety

Electrical hazards (DC supply voltage)
This equipment conforms with IEC safety Class III, meaning that for continued safety it must only
be connected to supplies and signal sources which conform to ‘Separated Extra-Low Voltage’ (SELV
and SELV-E) voltage and insulation requirements. No hazardous voltages are generated internally.
See the data sheet for the maximum permitted voltage levels that can be applied.
Do not remove equipment covers as this may result in personal injury. There are no user-serviceable
parts inside.
Refer all servicing to qualified personnel.
Heavy equipment
The weight of this equipment exceeds the 18 kg (40 lb) guideline for manual handling by a single
person. To avoid the risk of injury, an assessment should be carried out prior to handling which takes
account of the load, workplace environment and individual capability, in accordance with European
Directive 90/269/EEC and associated National Regulations.
Toxic hazards
Some of the components used in this equipment may include resins and other materials which give
off toxic fumes if incinerated. Take appropriate precautions, therefore, in the disposal of these items.
Beryllium copper
It is possible that some mechanical components within this equipment may be manufactured from
beryllium copper. This is an alloy with a beryllium content of approximately 5 %. It represents no risk
in normal use.
The material should not be machined, welded or subjected to any process where heat is involved.
It must be disposed of as “special waste”.
It must NOT be disposed of by incineration.
Short circuited/bent pins
Before replacing a module into the chassis, check inside the chassis that no debris is present between
pins on the backplane connectors, and that no pins on the backplane connectors are bent or
damaged. Check the module’s connectors in the same way. Short-circuits can damage the module
and chassis, and may cause fire.
If debris is present, ensure that no power is applied to the chassis, and carefully remove the debris
with an antistatic brush.
The module should slide smoothly and easily into the slot. If you feel resistance, remove the module
and check for obstructions or damage, and that the module is compatible with the chosen slot.

Hot surfaces
Take care when touching a module which has run for a prolonged period; the surface temperature
can become high.
Static-sensitive components
This equipment contains static-sensitive components which may be damaged by handling.
