Support Functions
Switching Matrix Control
Step 3. To initialize the E5250A
In the CONFIG MODE field, select the RESET E5250A softkey. All the E5250A
settings will be initialized.
Step 4. To select configuration mode
In the CONFIG MODE field, select the E5250A configuration mode, either AUTO
or NORMAL, using the softkey. Note that changing the mode initializes the
E5250A setup except for the configuration mode.
AUTO Sets auto configuration mode. In this mode, the installed cards
are treated as one card. For example, if the E5252As are
installed in slots 1 to 4, the E5250A works as a 48 output
matrix.
NORMAL Sets normal configuration mode. Each card is considered
independently. Each card works as a 12-output matrix.
Step 5. To select port function
In the PORT FCTN field, select the port function using the following softkeys. You
cannot use the bias port function and the couple port function simultaneously.
NO FCTN Disables the port function.
BIAS PORT Enables the bias port function connecting the input bias port to
all output ports that are disconnected from other input ports.
Select the bias port using the BIAS PORT field.
COUPLE PORT Enables the couple port function that is effective for the kelvin
connection. Select the coupled ports in the COUPLE PORT
STATUS field.
NOTE Connection after port function changed
Changing the port function does not change the connection setup of the E5250A.
However, by way of exception, changing the port function from the bias port
function to the couple port function or no function will disconnect the output ports
from the input port that has been used as the bias port.
