Keysight E3633A and E3634A User’s Guide 183
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 Keysight E3633A and Keysight 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 isolated from the
control circuit and the power supply.
