Multiplexer

Channel

Descriptions and

Connections

The channel switches connect, through the AT, BT, and CT Tree Switches,
to the Common Terminals.  Closing a channel using SCPI automatically
closes the appropriate tree switch for connections.  For example, a channel
00 closure automatically closes the AT Tree Switch.  To close the tree
switches using register programming, use channel number 90, 91, or 92 for
the AT, BT, or CT Tree Switches, respectively. 

The multiplexer also has an additional tree switch called the DT Tree
Switch.  It connects the DT Tree Switch Terminals, when closed, to any
channel.  Use this tree switch for ohms measurements.  This connects the
ohms current source to the channels inside the module.  Use channel
number 93 to select this tree switch.
