Injection Tip Usage
There are four injection tips included with the ChipSHOUTER.
Two 4mm tips and two 1mm tips, each with both “clockwise”
(CW) and “counter-clockwise” (CCW) versions. The size of the
tips refers to the diameter of the ferrite core inside the
coil, and the CW/CCW refers to the wrap direction of the
wire around the ferrite core. The wrapping direction can be
used to specify a positive or negative voltage induced into
a specific target (you may need to experiment to determine
which wrap direction corresponds to positive/negative on
your specific example).
Looking into the end of the tip, you will notice the top
conductor always goes to the outside of the coil. This lead
connects to the SMA shield (which is the lower or negative)
voltage. This is done to keep the highest voltage on the in-
side of the probe. Figure 8 shows the detail of the probe
construction underneath the opaque label.
