with the PWRVIEW
software.
1. Connect the PA3000 to the computer with the PWRVIEW software installed using
the supplied USB cable. Ethernet or GPIB can also be used, if desired.
2. Open the PWRVIEW software by double-clicking the desktop icon.
3. Click the Add button to connect the PA3000. All available instruments will be listed
in the selection panel.
4. Select the desired instrument (the PA3000) and then click Connect.
NOTE: There are various default applications and compliance tests on the left panel
from which you can select. This example discusses the AC-DC LED Driver efficiency
measurement. This method can also be used for similar AC-DC power supplies
5. Select LED Driver Efficiency under the Applications/Test section on the left panel and then
click the Wizard button. The wizard helps with wiring and shunt selections. A 1A shunt or
30A shunt can be selected based on the peak input and output currents.
6. Make changes on the setup wiring as suggested.
