ANALYZER SYSTEM ARCHITECTURE
The NGA 2000 CLD is available as a "stand-alone ana-
lyzer" or as a "blind" Analyzer Module (AM). The CLD
analyzer module can be part of the stand-alone analyzer
or a component of an analyzers system (Fig. A-1).
The NGA 2000 system made it possible, to configure
the CLD as a flexible "stand-alone analyzer" consisting
of a CLD "Analyzer Module", a Platform (complete with
front panel display/operator interface), and input/output
(I/O) modules.
The “analyzer module” is a “blind” analysis unit but re-
tains all the advanced design features. The AM variant
is designed for integration as part of a NGA 2000 analy-
sis system or special customer developed networks.
The platform/MLT´s front panel can act as operator in-
terface for a stand-alone analyzer or as the a central
interface for multiple Analyzer Modules. In multi anal-
yzer systems, this feature eliminates duplication of the
display/operator interface. In addition to the obvious op-
erational benefits there are significant cost and system
packaging advantages not possible with conventional
analyser configurations.
This flexible network communication architecture is
shown in the schematic of Fig. A-2.
