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.
Figure 41 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.
You may only connect pin 12–13, and pin 14–15, damage may result if any
other paths are short-circuited.
