Output Connections and Operating Information
Introduction
This chapter explains how to make connections to the output terminals located on-the rear of your power supply. Some
general operating information is included in this chapter to help you understand how the power supply operates under
various load conditions. This information applies whether you are operating the supply via the front panel or the HP-IB.
Output Ranges
Figure 4-1 identifies the output combinations that are available on the power supply. Each output can operate as a
constant voltage (CV) or constant current (CC) source over a wide variety of output voltage and current combinations. In
addition, each output has an active downprogrammer which operates at currents up to approximately 110% of the
maximum positive current rating of the output. This means that each output can actively sink as well as source its
maximum rated output current. At voltages below 2.5 V, a downprogramming resistor continues downprogramming until
the voltage reaches approximately zero volts.
