U3042AE12 DUT Control Lines
DUT Control Lines
The 15 pin female D-Sub connector on the front panel provides 8 latched data connections
that can be used to control your DUT. An adjustable voltage source (+2 to +5 Vdc) is
provided on the front panel. A positive or negative external source can be used. Refer to
Table 14 and Figure 49 on page 60.
Setting the DUT Control Interface
This section describes how to control the DUT control lines. Refer to “Controlling the Test
Set with N5242A or N5230C” on page 40 or “Controlling the Test Set with N5230A” on
page 17. For more information regarding the control lines, see Table 12 and Table 13.
