5-14 Agilent E5250A User’s Guide, Edition 9
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.
