General information regarding the CE marking
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 emmission 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 im-
munity should be observed:
1. Data cables
For the connection between instruments resp. their 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 cables HZ72S and HZ72L from HAMEG are 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 equip-
ment an 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 in-
terior 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 RF fi elds of even higher frequen-
cies 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.
