CS Limit
The CS Limit module defines voltage
and current levels to which the device under investigation will be
subjected. During a CS analysis the signal is injected on the at the location specified by the user. The
amplitude of the injected signal is then calculated at each end of the
conductors. Because of phase shift and losses across the length of the
conductors the signals at either end of the conductors will likely not be the
same as the signal at the injection point. The signal levels at the ends
of the conductors are then used to calculate the current and voltage induced in
the left-hand circuit
and right-hand circuit
components.
The CS Limit is defined by entering frequency/amplitude
pairs in tabular format on the Limit form, as shown in the following
figure. A graph of the limit is generated automatically. At
frequencies between each frequency entered in the Limit table the field
amplitude is calculated by linear interpolation. The following figure
shows a CS Limit defined in MIL-STD-461E, for example.
limits are
generally specified by regulatory agencies, e.g. CENELEC for the European Union,
or by the procuring agency in the case of military equipment. Refer to
applicable conducted susceptibility requirements for your equipment to determine
the frequency/amplitude values to enter.
Once the limit information has been entered the status bar
beneath the Limit button on the RE Analyst form is changed from
red to green. More:
