optional power/signal decoupler (P/N 27560-01) to interface the sensor driver module to
both the power supply and an external counter.
A basic understanding of the physics employed in the G-822A, and optically pumped
resonance magnetometers in general, is valuable for troubleshooting new installations and
for achieving optimum results during field use, but is not essential for either. Such basic
information can be found in the Appendix of this manual.
2.0 SYSTEM COMPONENTS
The basic system components of the G-822A consist of the sensor module, a sensor driver
module, and an interconnect cable that is permanently attached to the sensor module and
detachable from the sensor driver module. These components are identified in Figure 2.
The weights, dimensions, and connector’s specifications for these components and
ancillary system components are listed in the Table 1.
