P1401 and P1402 field sources
Figure 2 and Figure 3 show the P1401 and P1402 field source which generate a magnetic
test field. Both field sources have two plug connectors, an RF power input (N type) to power the
field source and a measurement output (SMB type) at the top. The power input is marked RF
the measurement output is marked i

conductor
On the inside of the field source, the RF power input is connected to the end of the
electric conductor located at the bottom of the field source. The other end of the electric conductor
is connected to ground of the field source and thus causes a short circuit in the RF current path.
The resulting RF current i
