Internal Voltage Supply Configuration
The output voltage of pin 12 can be adjusted from +2 to +5 V. Perform the following procedure to set the
voltage:
1. Turn
on
the test set.
2. Measure the voltage between pin 12 and 15 using a multimeter.
3. Rotate the voltage adjustment trimmer on the rear panel until the multimeter indicates the selected
voltage.
illustrates an example of the connection between the DUT and the test set using
the internal dc
power supply. Connect pin 12 to pin 13 and pin 14 to pin 15 to provide the ground path. Connect the control
lines to the external DUT.
CAUTION
You may only connect pin 12–13, and pin 14–15, damage may result if any other paths are
short-circuited.
