Agilent 7820 GC Service
This section describes the following circuit boards and their
connections.
Some connectors are marked MTC, which stands for
Manufacturing Test Connector. There may or may not be a
connector loaded on the board. MTCs are used at the factory to
connect to test equipment so that the board can be exercised
without the need for a GC. These connectors are not used when
the board is installed in an instrument.
