Most DIODES and MOSFETs can be tested by measuring the forward-to-back resistance of their
junctions using a standard ohmmeter. MOSFETS, however, are classed as ESD-sensitive devices; and
care should be exercised when handling or testing them.
INTEGRATED CIRCUITS (ICs) have revolutionized the electronics industry. They are rugged,
compact, and inexpensive. There is a wide assortment of equipment on the market designed for testing
BATTERIES are common to a large number of both electronic test equipment and operational
equipment. You should be familiar with the different types of batteries, their test requirements, and the
safety precautions to be followed.
RF ATTENUATORS and RESISTIVE LOADS are common devices that are widely used for
attenuating rf signals and impedance matching. Resistive loads can be tested with a standard ohmmeter,
and rf attenuators are normally tested through the rf substitution method.
