Sample program
Example 8-1 shows a sample program to execute the self-test. This program is stored on
the sample program disk under the filename “selftest.bas”.
This program executes the self-test and displays the result.
Line 30 Sets the GPIB address.
Lines 50 to 70 Executes the self-test and reads out the result.
Line 100 If the error code is 0, displays the “ALL TEST PASS” message.
Lines 120 to 320 If the error code is not 0, displays the test item that has failed.
Example 8-2 Executing the self-test (selftest.bas)

30 ASSIGN @Agt4288a TO 717
40 !
50 PRINT "Now testing..."
60 OUTPUT @Agt4288a;"*TST?"
70 ENTER @Agt4288a;Result
80 !
90 IF Result=0 THEN
100 PRINT "ALL TEST PASS"
110 ELSE
120 IF BIT(Result,0)=1 THEN
130 PRINT "TEST FAIL: RAM"
