FIGURE 1
Base Station/Diode Pod Assembly
The assembly shown in Figure 1 consists of four Printed
Circuit Board (PCB) assemblies. The lower board is the
electrometer board. When it is used as a Diode Pod, it converts
the current from the radiation detection diodes to digital
values for transmission back to the Base Station. When it is
used as a Base Station, it receives data from a Diode Pod and
relays it to an Operator Module or a Personal Computer via a
cable. The board being held in position by the pliers is a
battery pack consisting of three “AAA” NiMH batteries. The
third board is the RF transceiver. The fourth is the antenna
mounting pad (Not visible).

The first three boards slide into grooves in the extruded
aluminum case. The picture shows them in their approximate
positions. Refer to the following assembly drawing for a more
