Kelvin Connections
To Control Switching Matrix
The Agilent B2200 switching matrix provides the couple mode function. When the couple
mode is ON, the matrix switches will be controlled to connect the specified couple input
port to the specified couple output port. The couple input ports have to be set to the input
ports used for the Kelvin connection.
To set couple input ports
There is two ways to set the couple input ports. First way is to set the couple ports
automatically by using the couple port detection capability. And the second way is to set
the couple ports manually.
• Setting the couple ports automatically
Enter the :ROUT:COUP:PORT:DET command. The input ports connected to the
Kelvin cable will be detected automatically, and will be assigned as the couple input
ports.
• Setting the couple ports manually
Enter the :ROUT:COUP:PORT card_number, ‘ports’ command to specify the couple
ports. For example, the following command sets two couple ports (input port pairs 1-2
and 3-4) for the all switch module installed in the Agilent B2200.
:ROUT:COUP:PORT ALL,’1,3’
To control Kelvin connection path
After the couple input ports are defined, set the couple mode ON by using the
:ROUT:COUP ON command. After that, the :ROUT:CLOS command will control the
switches to connect the specified couple input port to the specified couple output port, and
the :ROUT:OPEN command will control the switches to disconnect the specified couple
input port from the specified couple output port.
The following example connects the input ports 1 and 2 (couple input port) to the output
ports 11 and 12 respectively.
:ROUT:COUP:PORT ALL,’1,3’
:ROUT:COUP ON
:ROUT:CLOS (@00111)
