4.1 Putting into Operation
This section describes the basic steps to be taken when setting up the R&S
AREG for the first time.
Risk of injury due to disregarding safety information
Observe the information on appropriate operating conditions provided in the
data sheet to prevent personal injury or damage to the instrument. Read
and observe the basic safety instructions provided with the instrument, in
addition to the safety instructions in the following sections. In particular:
●Do not open the instrument casing.
Risk of injury due to laser radiation
A laser (laser class 1M) is installed in the device.
Do not open the device. The device may only be opened by authorized ser-
vice personnel.
Risk of instrument damage due to inappropriate operating conditions
Specific operating conditions are required to ensure accurate measure-
ments and to avoid damage to the instrument. Observe the information on
appropriate operating conditions provided in the basic safety instructions
and the instrument's data sheet.

Instrument damage caused by electrostatic discharge
Electrostatic discharge (ESD) can damage the electronic components of the
instrument and the device under test (DUT). Electrostatic discharge is most
likely to occur when you connect or disconnect a DUT or test fixture to the
instrument's test ports. To prevent electrostatic discharge, use a wrist strap
and cord and connect yourself to the ground, or use a conductive floor mat
and heel strap combination.
Risk of instrument damage due to inappropriate operating conditions
An unsuitable operating site or test setup can damage the instrument and
connected devices. Before switching on the instrument, observe the infor-
mation on appropriate operating conditions provided in the data sheet. In
particular, ensure the following:
●All fan openings are unobstructed and the airflow perforations are unim-
peded. A minimum distance of 10 cm to other objects is recommended.
●The instrument is dry and shows no sign of condensation.
●The instrument is positioned as described in the following sections.
●The ambient temperature does not exceed the range specified in the
data sheet.
●Signal levels at the input connectors are all within the specified ranges.
●Signal outputs are connected correctly and are not overloaded.

14Getting Started 1430.3572.02 ─ 04
Risk of instrument damage due to inappropriate handling
Handle all waveguide components with care.
●If the R&S AREG is not used, cover the antenna to prevent dust or other
objects from getting into the waveguide.
●Do not plug or unplug the TRX CTRL cable from the R&S AREG fron-
tend or base unit if the device is running.
●Do not subject the TRX CTRL or IF cables to a tight bend radius.
4.1.1 EMI Suppression
Electromagnetic interference (EMI) may affect the measurement results.
To suppress generated Electromagnetic Interference (EMI),
●Use suitable shielded cables of high quality. For example use double-shielded
RF, BNC and LAN cables (CAT6 STP).
Note: USB cables are of varying and often poor quality. Therefore, check the
quality of each individual USB cable as described in the service manual.
●Always terminate open cable ends.
Note the EMC classification in the data sheet.
4.1.2 Unpacking and Checking the Instrument
Unpack the R&S AREG carefully and check the contents of the package.
●Check if all items listed on the delivery note, including this getting started
manual, are included in the delivery.
●Check the R&S AREG for any damage.
If the contents are damaged, immediately contact the carrier who delivered
the package.

Packing material
Retain the original packing material. If the instrument needs to be transpor-
ted or shipped later, you can use the material to protect the control ele-
ments and connectors.
4.1.3 Accessory List
The instrument comes with the following accessories:
●Power cable
●Getting Started printed manual
4.1.4 Placing or Mounting the Instrument
The R&S AREG is designed for use under laboratory conditions, either on a
bench top or in a rack using the standard rackmount kit.
Bench top operation
If the R&S AREG is operated on a bench top, the surface must be flat. The instru-
ment can be used in horizontal position, standing on its feet, or with the support
feet on the bottom extended.
Risk of injury if feet are folded out
The feet can fold in if they are not folded out completely or if the instrument
is shifted. Collapsing feet can cause injury or damage the instrument.
●Fold the feet completely in or out to ensure stability of the instrument.
Never shift the instrument when the feet are folded out.
●When the feet are folded out, do not work under the instrument or place
anything underneath.
●The feet can break if they are overloaded. The overall load on the fol-
ded-out feet must not exceed 500 N.

Risk of injury when stacking instruments
A stack of instruments can tilt over and cause injury if not stacked correctly.
Furthermore, the instruments at the bottom of the stack can be damaged
due to the load imposed by the instruments on top.
Observe the following instructions when stacking instruments:
●Never stack more than three instruments. If you need to stack more
than three instruments, install them in a rack.
●The overall load imposed on the lowest instrument must not exceed
500 N.
●It is best if all instruments have the same dimensions (width and length).
If you need to stack smaller instruments on the top, the overall load
imposed on the lowest instrument must not exceed 250 N.
●If the instruments have foldable feet, fold them in completely.
Mounting in a rack
The R&S AREG can be installed in a rack using a rack adapter kit (Order No. see
data sheet). The installation instructions are part of the adapter kit.
Risk of instrument damage due to insufficient airflow in a rack
If you mount several instruments in a rack, you need an efficient ventilation
concept to ensure that the instruments do not overheat. Insufficient airflow
for a longer period can disturb the operation and even cause damage.

4.1.5 Connecting AC Power
The R&S AREG is equipped with an AC power supply connector, that can be
operated with different AC power voltages. Once it is connected, the instrument
automatically adjusts to the given voltage. Refer to the data sheet for the require-
ments of voltage and frequency. There is no need to set the voltage manually or
change fuses.
To connect the AC supply
► Connect the R&S AREG to the AC power source using the supplied power
cable.
Note: Since the instrument is designed in compliance with standard EN
61010-1 safety class I, it must only be connected to an outlet that has a
ground contact.
Characteristics of the AC power supply:
●100 V to 240 V AC
4.1.6 Cabling of Front End and Base Unit
To connect the front end
1. Connect the IF cable with the label RX IF OUT to the Rx IF Out connector of
the front end.
2. Connect the IF cable with the label TX IF IN to the Tx IF IN connector of the
front end.
3. Connect the control cable to the Control connector of the front end.

To start the R&S AREG
Starting the R&S AREG requires that it is connected and turned on.
► At the front panel, press the [On/Standby] key briefly.
The instrument boots the operating system and starts the instrument firmware.
After booting, the instrument is in the state before the last power off (standby
or ready), indicated by the color of the [On/Standby] key's LEDs:
● Green: the R&S AREG is running and ready for operation.
All modules are power-supplied.
● Orange: the R&S AREG is in standby mode (main AC power switch is in
position "I").
To switch between standby and ready state, briefly press the [On/Standby]
key.
If a previous session was terminated regularly, the instrument uses the last setup
with the relevant instrument settings.
► To set up a new configuration, press the [Preset] key to return the instrument
to its defined reset/preset state.
To shut down and turn off the R&S AREG
Risk of losing data
If you switch off the running instrument using the rear panel switch or by
disconnecting the power cord, the instrument loses its current settings. Fur-
thermore, program data can be lost.
Press the On/Standby key first to shut down the application properly.
1. Press the [On/Standby] key.
The current setup is saved, the operating system shuts down and sets the
instrument to standby state.
The [On/Standby] LED must be orange.
2. Turn off the main AC power switch at the rear panel of the R&S AREG (posi-
tion "0" (off)).
The instrument is no longer supplied with AC power.
