3.25.23 Test sequence programming example
The following QuickBASIC 4.5 program uses the CEC/KPC IEEE-488 interface card. The stair-
case sweep test will measure current at each voltage step. The test will sweep from 0V to 20V
in 2V steps. When the test is finished, the readings (which are stored in the buffer) are dumped
to the computer and then displayed on the CRT.
