P1202 / P1301 L-ESD set
P1202 Magnetic Field Source
6.3
Figure 6 shows the P1202 ESD magnetic field source.
The P1202 has three plug connectors, a high-voltage input (Fischer connector) to supply the
field source, a digital control input (12 pin header) to control the field source and a measurement
output (SMB connector) at the top.
The high-voltage input is marked
HV
in
and the measurement output is marked
i
out
.
Figure 6: P1202 ESD field source with 3 cm long electric conductor
On the inside of the P1202 ESD field source (see
Figure 3)
, the HV power input is connected to
the pulse shaping circuit. The output of the pulse shaping circuit is connected to the
electric conductor located at the bottom of the field source. The end of the electric conductor is
connected to ground of the field source and thus causes a short circuit in the current path.
The resulting current
i
P
generates a magnetic field that develops around the electric conductor.
