Controlling the E5250A

 

Switch Control Basics

 

Bias Mode

 

Connection rule cannot be specified for the input Bias Port, which can always be

NOTE

 

connected to multiple output ports.

 

Connection sequence (to connect input Bias Port to output ports) is always

 

Break-Before-Make.

 

Bias Port and Couple Port cannot be set to the same port number.

 

Bias Mode is effective for the input Bias Port:

 

 

• For the E5255A, input Bias Port is the dedicated BIAS port on the E5255A

 

• For the E5252A, input Bias Port is the input port (1 to 10) that you select.

 

When Bias Mode is ON, the input Bias Port is connected to all bias enabled output

 

ports that are not connected to any other input ports. You cannot directly control

 

which output ports are connected to the input Bias Port:

 

• If another input port is disconnected (:ROUT:OPEN command) from a bias

 

enabled output port, the output port is automatically connected to the input Bias

 

Port.

 

• If another input port is connected (:ROUT:CLOS command) to a bias enabled

 

output port, the output port is automatically disconnected from the input Bias

 

Port.

 

Bias disabled output ports are never connected to the input Bias Port when Bias

 

Mode is ON.

 

When Bias Mode is OFF, the input Bias Port is the same as the other input ports, so

 

relays can be controlled directly to connect to output ports.

 

You can independently control the Bias Mode for each card installed in the E5250A.

 

Refer to [:ROUTe]:BIAS[:STATe] in Chapter 7.
