Step 7: End the Connection

Step 7: End the Connection

Last updated: April 14, 2005

In this step you end the connection between the access terminal and test set, as well as prepare the test set to test the next access terminal.

To end the connection you can choose to only close the data connection which makes the session still open (see Close the Connection ) or choose to close the session which will close the data connection and the session at one time (see Close the Session ).

To prepare to test the next access terminal, you should then partially preset the test set. See Partially Preset the Test Set .

Close the Connection

To close the connection, you:

  1. Set the Data Connection State Change Detector timeout.
  2. Arm the Data Connection State Change Detector .
  3. Send the CALL:FUNCtion:DATA:STOP command.
  4. Query the state of the data connection using the CALL:DCONnected[:STATe]? or CALL:SOPen? query.

An excerpt from the comprehensive example program is shown below:

2130 ! STEP 7: END THE CONNECTION
2140 !**************************************************************************

12910       DISP "Closing data connection"
12920 !
12930       OUTPUT Testset;"CALL:DCONNECTED?"
12940       ! Checks connection status
12950       ENTER Testset;Data_stopped
12960 !
12970       IF Data_stopped=0 THEN
12980           DISP "Data connection closed"
12990 !
13000       ELSE
13010           OUTPUT Testset;"CALL:DCONNECTED:TIMEOUT 10"
13020           ! Set connection change detector timeout
13030           OUTPUT Testset;"CALL:DCONNECTED:ARM"
13040           ! Arm the connection state change detector
13050           OUTPUT Testset;"CALL:FUNCTION:DATA:STOP"
13060           ! Close the data connection
13070           OUTPUT Testset;"CALL:DCONNECTED?"
13080           ! Query the data connection status
13090           ENTER Testset;Data_stopped
13100 !
13110           IF Data_stopped=1 THEN
13120               Print_title("Data connection could not be closed")
13130               Print_title("Ending Testing")
13140               GOTO End_program
13150           END IF
13160 !
13170           DISP "Data connection closed"
13180       END IF

Close the Session

Before disconnecting the AT under test and connecting a new AT to test, you should close the session using the CALL:SCLose command. This will close the data connection and the session at one time. See Close Session Before Testing New AT .

Partially Preset the Test Set

Partially presetting the test set using the SYSTem:PRESet3 command will also return the data connection to the idle state, as well as stop any measurements in progress.
