General information regarding the CE marking
B&K instruments fulfill the regulations of the EMC directive. The conformity test made by B&K is based on the actual
generic and product standards. In cases where different limit values are applicable, B&K 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 influence 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 immunity should be observed:
1. Data cables
For the connection between instruments resp. their interfaces and external devices, (computer, printer etc.) sufficiently shielded
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 long. If an interface has several connectors only one connector must have a connection to
a cable.
Basically interconnections must have a double shielding.
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 long. Signal lines must shielded (coaxial
cable - RG58/U). A proper ground connection is required. In combination with signal generators double shielded cables (RG223/
U, RG214/U) must be used.
3. Influence on measuring instruments.
Under the presence of strong high frequency electric or magnetic fields, even with careful setup of the measuring equipment an
influence 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 specifications may result from such conditions in individual cases.
4. RF immunity of oscilloscopes.
4.1 Electromagnetic RF field
The influence of electric and magnetic RF fields may become visible (e.g. RF superimposed), if the field 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 fields.
Although the interior of the oscilloscope is shielded by the cabinet, direct radiation can occur via the CRT gap. As the bandwidth
of each amplifier stage is higher than the total –3dB bandwidth of the oscilloscope, the influence RF fields 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.
