Electronic load
Many of the test procedures require the use of a variable
load resistor capable of dissipating the required power.
Using a variable load resistor requires that switches should
be used to connect, disconnect, and short the load resistor.
An electronic load, if available, can be used in place of a
variable load resistor and switches. The electronic load is
considerably easier to use than load resistors. It eliminates
the need for connecting resistors or rheostats in parallel to
handle power. It is much more stable than carbon- pile load,
and it makes easy work of switching between load conditions
as is required for the load regulation and load response
tests. Substitution of the electronic load requires minor
changes to the test procedures in this chapter.
Programming
Most performance tests can be performed from the front
panel. However, a GPIB or RS- 232 controller is required to
perform the voltage and current programming and readback
accuracy tests.
The test procedures are written assuming that you know
how to program the power supply either from the front
panel or from the GPIB or RS- 232 controller. Refer to
Chapter 3, “Output Settings and Operation Commands” for
detailed instructions on remote programming.
