Analog detector output (optional)
If present, the analog detector is a 9-pole D-sub connector (female on rear
CompactGC). This output provides a high stable, high resolution (20 bits) analog signal.
In order to preserve the quality as good as possible, short cables are advised. Beside
the output signal, two additional connections are important: shield and ground. The
shield is not connected at the CompactGC side, and is necessary to protect the signal
from external influences. This cable needs to be connected at the data system. The
ground connection is necessary to equal the ground level of the CompactGC to the
data system, and is important for safety reasons, and omitting damage to the system.
