Agilent Technologies Agilent E5250A manual Couple Port Relay Connections

Controlling the E5250A

Switch Control Basics

The two output ports are determined by the channel_list parameter of the :ROUT:CLOS command, and the lower output port number is always odd.

So, when you execute :ROUT:CLOS or :ROUT:OPEN command for the couple port, four relays operate synchronously as shown in Figure 5-3.

For example, assume that input ports 1 and 2 are coupled, and that the Couple Port mode is ON:

1.If :ROUT:CLOS command specifies to connect channel 0105, relays are closed to realize two channels (0105 and 0206).

2.If :ROUT:OPEN command specifies to disconnect channel 0105, all four relays between the two input ports and two output ports are opened.

NOTE	For each E5252A installed in the E5250A, you can independently specify the same
	or different couple ports.
