Overview of the Power Supply Operation
E3632A User’s Guide 151
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 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 isolated from
the control circuit and the power supply.
