Safety Instructions
095.1000 Sheet 17
This unit has been designed and tested in accordance with the EC Certificate of Conformity and has left the
manufacturer’s plant in a condition fully complying with safety standards.
To maintain this condition and to ensure safe operation, the user must observe all instructions and warnings
given in this operating manual.
1. The unit may be used only in the operating con-
ditions and positions specified by the manufac-
turer. Unless otherwise agreed, the following
applies to R&S products:
Pollution severity 2, overvoltage category 2, IP
degree of protection 2X, altitude max. 2000 m.
The unit may be operated only from supply net-
works fused with max. 16 A.
2. For measurements in circuits with voltages Vrms
> 30 V, suitable measures should be taken to
avoid any hazards.
(using, for example, appropriate measuring
equipment, fusing, current limiting, electrical
separation, insulation).
3. If the unit is to be permanently wired, the PE
terminal of the unit must first be connected to
the PE conductor on site before any other con-
nections are made (installation and cabling of
the unit to be performed only by qualified techni-
cal personnel).
4. For permanently installed units without built-in
fuses, circuit breakers or similar protective de-
vices, the supply circuit must be fused such as
to provide suitable protection for the users and
equipment.
5. Prior to switching on the unit, it must be ensured
that the nominal voltage set on the unit matches
the nominal voltage of the AC supply network.
If a different voltage is to be set, the power fuse
of the unit may have to be changed accordingly.
6. Units of protection class I with disconnectible
AC supply cable and appliance connector may
be operated only from a power socket with
earthing contact and with the PE conductor con-
nected.
7. It is not permissible to interrupt the PE conduc-
tor intentionally, neither in the incoming cable
nor on the unit itself as this may cause the unit
to become electrically hazardous.
Any extension lines or multiple socket outlets
used must be checked for compliance with rele-
vant safety standards at regular intervals.
8. If the unit has no power switch for disconnection
from the AC supply, the plug of the connecting
cable is regarded as the disconnecting device.
In such cases it must be ensured that the power
plug is easily reachable and accessible at all
times (length of connecting cable approx. 2 m).
Functional or electronic switches are not suit-
able for providing disconnection from the AC
supply.
If units without power switches are integrated in
racks or systems, a disconnecting device must
be provided at system level.
9. Applicable local or national safety regulations
and rules for the prevention of accidents must
be observed in all work performed.
Prior to performing any work on the unit or
opening the unit, the latter must be discon-
nected from the supply network.
Any adjustments, replacements of parts, main-
tenance or repair may be carried out only by
authorized R&S technical personnel.
Only original parts may be used for replacing
parts relevant to safety (eg power switches,
power transformers, fuses). A safety test must
be performed after each replacement of parts
relevant to safety.
(visual inspection, PE conductor test, insulation-
resistance, leakage-current measurement, func-
tional test).
10. Ensure that the connections with information
technology equipment comply with
IEC950/EN60950.
11. Equipment returned or sent in for repair must be
packed in the original packing or in packing with
electrostatic protection.
12. Any additional safety instructions given in this
manual are also to be observed.

SMR General Overview of Manuals
1104.3430.12 E E-1
General Overview of Manuals
Operating Manual for Microwave Signal Generator SMR
This operating manual provides you with all the information necessary for putting into operation, manual
and remote control as well as repair of Microwave Signal Generator SMR and also contains
specifications of the instrument and available options.
The following models are described in this manual:
SMR20 1 GHz to 20 GHz (10 MHz to 20 GHz with Option SMR-B11)
SMR27 1 GHz to 27 GHz (10 MHz to 27 GHz with Option SMR-B11)
SMR30 1 GHz to 30 GHz (10 MHz to 30 GHz with Option SMR-B11)
SMR40 1 GHz to 40 GHz (10 MHz to 40 GHz with Option SMR-B11)
The contents of the chapters are as follows:
Data sheet informs you about guaranteed specifications relating to functions and
characteristics of the instrument and its options.
Chapter 1 contains all information about putting into operation (unpacking, connection to
AC supply, switching on and off), functional testing and installation of the
instrument, preset settings and views of the front and rear panel showing the
controls and connectors needed for operation.
Chapter 2 presents a brief introduction and typical settings to users working with the
SMR for the first time.
