Sample Application Programs Using VEE
Introduction
Execution Mode
The sample1.vee and sample2.vee programs have five execution modes, as
described below. The default is Offline mode.
NOTE If you do not use the Cascade Summit series semi-auto prober, use sample1.vee with
Online mode, standalone, or with the E5250A. The sample2.vee program is used for
sequential test, using the semi-auto prober. The test results for sample2.vee will be
meaningless in the Online mode without the prober.
• Offline mode
Select this mode if you do not use an instrument. After program execution, the
demo (dummy) data is returned as the test result.
• Online mode, standalone (4155/4156 only)
Select this mode if you use the 4155/4156 only. The test device is a single
MOSFET, as the 4155/4156 has four SMUs to connect and measure a 4-terminal
device simultaneously. A test fixture or manual prober is required to connect the
device.
• Online mode with E5250A
Select this mode if you use the 4155/4156 and E5250A. A test fixture or manual
prober is required to connect the devices.
• Online mode with semi-auto prober
Select this mode if you use the 4155/4156 and the Cascade Microtech Summit
series semi-auto prober. The test device is a single MOSFET, as the 4155/4156
has four SMUs to connect and measure a 4-terminal device simultaneously.
• Online mode, fully automatic
Select this mode if you use the 4155/4156, E5250A, and the Cascade Summit
series semi-auto prober.
NOTE The sample programs require that the E5250A be installed with two E5252A matrix
cards. They must be installed in slots 1 and 2 of the E5250A mainframe.
