4.1 Putting into Operation
This section describes the basic steps to be taken when setting up the R&S SMW
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 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.

16Getting Started 1412.9220.02 ─ 21
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.
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.
Putting into Operation

Preparing for Use
R&S®SMW200A
17Getting Started 1412.9220.02 ─ 21
●Use the cable R&S SMU-Z6 for connection to the DIG I/Q interfaces of the
instrument. The required cable is available under part number 1415.0201.02.
●For connection to the HS DIG I/Q interfaces of the instrument, use:
– QSFP+ passive copper cable with max. length of 3 m
– Active optical cable with max. power class 2 module (2.0 W max. power
consumption)
Note the EMC classification in the data sheet.
4.1.2 Unpacking and Checking the Instrument
Unpack the R&S SMW 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 SMW 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.
Risk of injury during transportation
The carrying handles at the front and side of the casing are designed to lift
or carry the instrument. Do not apply excessive force to the handles. If a
handle is ripped off, the falling instrument can cause injury.
Be aware of the weight of the instrument when lifting it. Observe the infor-
mation on transporting heavy instruments in the basic safety instructions
provided with the instrument.
4.1.3 Accessory List
The instrument comes with the following accessories:

4.1.4 Placing or Mounting the Instrument
The R&S SMW 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 SMW 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.

19Getting Started 1412.9220.02 ─ 21
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 SMW 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 SMW is equipped with an AC power supply connector, that can be oper-
ated with different AC power voltages. Once it is connected, the instrument auto-
matically 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.
The AC supply and power switch is at the rear of the unit.
To connect the AC supply
► Connect the R&S SMW 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
●50 Hz to 60 Hz; 400 Hz
●7.3 A to 4.6 A
4.1.6 Turning the Instrument On and Off
To turn on the R&S SMW
1. Connect the instrument to the AC supply.
2. Turn on the main AC power switch at the rear panel of the R&S SMW (posi-
tion "I" (on)).
The instrument is supplied with AC power.
Warm-up time for OCXO
When the instrument is switched on, the OCXO requires an extended
warm-up time (see data sheet).
