Overview of Agilent E3632A Operation
142
In terms of performance, a linear regulated supply has a very p recise r egulating
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 E3632A contains 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.
