The ID number is only important if more than one analyzer is connected to the same
communications channel (e.g., a multi-drop setup). Different models of Teledyne Instruments
analyzers have different default ID numbers, but if two analyzers of the same model type are
used on one channel (for example, two MGFC7000E’s), the ID of one instrument needs to be
changed.
The ID can also be used for to identify any one of several analyzers attached to the same network
but situated in different physical locations.
