U3042AE12 DUT Control Lines
Setting the Variable Source Voltage
The output voltage of pin 12 can be varied from +2 to +5 V. Perform the following procedure
to set the voltage:
1. Turn On U3042AE12.
2. Measure the voltage between pin 12 and 15 using a multimeter.
3. Rotate the voltage adjustment trimmer on the front panel until the multimeter
indicates the appropriate voltage.
Connecting to the DUT Control Lines
Figure 47 illustrates an example of the connection between the DUT and the U3042AE12
without an external dc power supply. Connect pin 12 to pin 13 for +5 V, and pin 14 to pin 15
to provide the ground path. Connect each DUT control line to the external device under
test.
CAUTION You may only connect pin 12–13, and pin 14–15. Damage may result if any
other path is short–circuited.
