Electronic Load
Many of the test procedures require the use of a variable load capable of dissipating the required power. If a variable
resistor is used, switches must be used for connecting, disconnecting, and shorting the load resistor. For most tests, an
electronic load (see Table 2-1) is easier to use than a variable resistor. However, an electronic load may not be fast enough
for testing transient recovery time or may be too noisy for testing noise (PARD). In these cases, fixed load resistors of
suitable power dissipation can be used with minor changes to the test procedures given in this chapter.
