Overview of Agilent E3633A and Agilent E3634A Operation

In terms of performance, a linear regulated supply has a very precise regulating properties and responds quickly to variations of the line and load. Hence, its line and load regulation and transient recovery time are superior to supplies using other regulation techniques. The power supply also exhibits low ripple and noise, is tolerant of ambient temperature changes, and with its circuit simplicity, has a high reliability.

The Agilent E3633A and Agilent E3634A contain a linear regulated power supply. It is controlled by a control circuit that provides voltages to program the outputs. The power supply sends back to the control circuits a voltage representing the output at the terminals. The control circuits receive information from the front panel and send information to the display. Similarly the control circuits ‘’talk’’ to the remote interface for input and output with the GPIB and RS-232 interfaces. The remote interface is at earth ground and optically isolated from the control circuit and the power supply.
