General information regarding the CE marking

HAMEG instruments fulfi ll the regulations of the EMC directive. The
conformity test made by HAMEG is based on the actual generic- and
product standards. In cases where different limit values are applicable,
HAMEG applies the severer standard. For emission the limits for
residential, commercial and light industry are applied. Regarding the
immunity (susceptibility) the limits for industrial environment have
been used.
The measuring- and data lines of the instrument have much infl uence
on emission and immunity and therefore on meeting the acceptance
limits. For different applications the lines and/or cables used may
be different. For measurement operation the following hints and
conditions regarding emission and immunity should be observed:
1. Data cables
For the connection between instrument interfaces and external devices,
(computer, printer etc.) suffi ciently screened cables must be used.
Without a special instruction in the manual for a reduced cable length,
the maximum cable length of a dataline must be less than 3 meters and
not be used outside buildings. If an interface has several connectors
only one connector must have a connection to a cable.
Basically interconnections must have a double screening. For IEEE-bus
purposes the double screened cable HZ72 from HAMEG is suitable.
2. Signal cables
Basically test leads for signal interconnection between test point and
instrument should be as short as possible. Without instruction in the
manual for a shorter length, signal lines must be less than 3 meters
and not be used outside buildings.
Signal lines must screened (coaxial cable - RG58/U). A proper ground
connection is required. In combination with signal generators double
screened cables (RG223/U, RG214/U) must be used.
3. Infl uence on measuring instruments
Under the presence of strong high frequency electric or magnetic
fi elds, even with careful setup of the measuring equipment, infl uence
of such signals is unavoidable.

This will not cause damage or put the instrument out of operation. Small
deviations of the measuring value (reading) exceeding the instruments
specifi cations may result from such conditions in individual cases.
4. RF immunity of oscilloscopes.
4.1 Electromagnetic RF fi eld
The infl uence of electric and magnetic RF fi elds may become visible
(e.g. RF superimposed), if the fi eld intensity is high. In most cases
the coupling into the oscilloscope takes place via the device under
test, mains/line supply, test leads, control cables and/or radiation.
The device under test as well as the oscilloscope may be effected by
such fi elds.
Although the interior of the oscilloscope is screened by the cabinet,
direct radiation can occur via the CRT gap. As the bandwidth of
each amplifi er stage is higher than the total –3dB bandwidth of the
oscilloscope, the infl uence of RF fi elds of even higher frequencies
may be noticeable.
4.2 Electrical fast transients / electrostatic discharge
Electrical fast transient signals (burst) may be coupled into the
oscilloscope directly via the mains/line supply, or indirectly via test
leads and/or control cables. Due to the high trigger and input sensitivity
of the oscilloscopes, such normally high signals may effect the trigger
unit and/or may become visible on the CRT, which is unavoidable.
These effects can also be caused by direct or indirect electrostatic
discharge.
