Step 6. To set bias port (if you use the bias port function)
In the BIAS PORT field, enter the port number of the E5250A input port to be used
as the bias port. Available values are 1 to 10. Default value is 10.
NOTE Connection after input bias port changed
Changing the input port number of the bias port will disconnect the output bias ports
from the previous input bias port and connect them to the new input bias port.
Step 7. To set couple port (if you use the couple port function)
In the COUPLE PORT STATUS field, select the ON or OFF softkey to
enable/disable the couple port. The following input ports can be coupled:
• INPUT1 and INPUT2 can be coupled to port 1.
• INPUT3 and INPUT4 can be coupled to port 3.
• INPUT5 and INPUT6 can be coupled to port 5.
• INPUT7 and INPUT8 can be coupled to port 7.
• INPUT9 and INPUT10 can be coupled to port 9.
NOTE Operation of couple port
Coupled ports work as described below:
• When the coupled port is opened, coupled input ports INPUTm-1 and INPUTm
are disconnected from all output ports.
• When the coupled port is closed, coupled input ports INPUTm-1 and INPUTm
are connected as follows:
Input port INPUTm-1 is connected to output port n-1.
Input port INPUTm is connected to output port n.
Where, m and n are integers (even numbers). The maximum value is 10 for m, and
48 for n.
