Control Lines
The 15 pin female D-Sub connector on the rear 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 33 and
“Setting the Test Port Paths with Address and Data” on page 47 . See Table 13
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 40 and Table
14 on page 55 for control line pin location and description. Refer to “Internal
Voltage Supply Configuration” on page 56
and
“External Voltage Supply
Configuration” on page 57 for configurations.
