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 .
An excerpt from the comprehensive example program is shown below:
2120 !************************************************************************** 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
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 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.
