General remarks regarding the CE marking
Hameg measuring instruments comply with the EMI
norms. Our tests for conformity are based upon the rele-
vant norms. Whenever different maximum limits are optio-
nal Hameg will select the most stringent ones. As regards
emissions class 1B limits for small business will be ap-
plied. As regards susceptibility the limits for industrial en-
vironments will be applied. All connecting cables will influ-
ence emissions as well as susceptability considerably. The
cables used will differ substantially depending on the ap-
plication. During practical operation the following guide-
lines should be absolutely observed in order to minimize
emi:
1. Data connections
Measuring instruments may only be connected to external
associated equipment (printers, computers etc.) by using
well shielded cables. Unless shorter lengths are prescri-
bed a maximum length of 3 m must not be exceeded
for all data interconnections (input, output, signals, con-
trol). In case an instrument interface would allow connec-
ting several cables only one may be connected. In general,
data connections should be made using double-shielded
cables. For IEEE-bus purposes the double screened cable
HZ72 is suitable.
2. Signal connections
In general, all connections between a measuring instru-
ment and the device under test should be made as short
as possible. Unless a shorter length is prescribed a ma-
ximum length of 3 m must not be exceeded, also, such
connections must not leave the premises. All signal con-
nections must be shielded (e.g. coax such as RG58/U).
With signal generators double-shielded cables are man-
datory. It is especially important to establish good ground
connections.
3. External influences
In the vicinity of strong magnetic or/and electric fields even
a careful measuring set-up may not be sufficient to gu-
ard against the intrusion of undesired signals. This will not
cause destruction or malfunction of Hameg instruments,
however, small deviations from the guaranteed specifica-
tions may occur under such conditions.
DECLARATION OF CONFORMITY

The HAMEG Instruments GmbH herewith declares conformity of the
product:
Product name:
RF- Synthesizer 3 GHz
Type
:
HM8134-3, HM8134-3X
with
: HO820
Option
: HO880
complies with the provisions of the Directive of the Council of the European
Union on the approximation of the laws of the Member States
❙
relating to electrical equipment for use within defined voltage limits
(2006/95/EC) [LVD]
❙
relating to electromagnetic compatibility (2004/108/EC) [EMCD]
❙
relating to restriction of the use of hazardous substances in electrical and
electronic equipment (2011/65/EC) [RoHS].
Conformity with LVD and EMCD is proven by compliance with the following
standards:
EN 61010-1: 04/2015
EN 61326-1: 07/2013
EN 55011: 11/2014
EN 61000-4-2: 12/2009

EN 61000-4-6: 08/2014
EN 61000-4-11: 02/2005
For the assessment of electromagnetic compatibility, the limits of radio
interference for Class B equipment as well as the immunity to interference
for operation in industry have been used as a basis.
