CALORIMETERS are the most accurate type of test equipment used for measuring high power. As
power is applied to a calorimeter, its medium (either liquid or solid) is heated. The heat that is produced is
directly proportional to the amount of applied power. The amount of applied power is determined by
measuring the change in temperature of the medium.
Today's ELECTRONIC FREQUENCY COUNTERS are capable of measuring frequencies from
dc to 40 GHz. Most have added features that enable period averaging, time-interval measurements, and
scaling. Frequency counter accuracy can be extended by using an external frequency standard in lieu of
its internal frequency standard.
