Control Lines
The 15 pin female D-Sub connector on the front panel provides 8 latched data lines
that can be used to control your device under test (DUT. The lines can be controlled
with the multiport external test set control, or test set I/O commands. Refer to
“External Test Set Control Feature” on page 3 6 and “Setting the Control Lines with
Address and Data Values” on page 5 8 . See Table 1 3 for DUT control line
specification.
The output voltage of the lines can be from the internal adjustable voltage source
(+2 to +5 Vdc), or an external DC power supply depending on how the connection to
the control line is configured. When using an external power supply a positive or
negative voltage can be used. Refer to
Figure 4 4 and Table 1 4 on page 5 5 for control
line pin location and description. Refer to “Internal Voltage Supply Configuration” on
page 5 6 and “External Voltage Supply Configuration” on page 5 7 for configurations.
