SUMMARY
Now that we have completed this chapter, let's review the more important points.
The type of meter used to measure power is the POWER METER.
One type of wattmeter is the AN/URM-120. It is an IN-LINE TYPE WATTMETER.
The principal function of a SIGNAL GENERATOR is to produce an alternating voltage of the
desired frequency and amplitude, which has the necessary modulation for the test or measurement
concerned.
There are basically two types of signal generators: AF and RF FREQUENCY GENERATORS.
The instrument used to determine the frequency of a signal is the FREQUENCY COUNTER.
An instrument of great value to a technician in troubleshooting digital integrated logic circuits is the
LOGIC PROBE.
The HUNTRON TRACKER 2000 is a versatile piece of test equipment that is used to compare
known good devices against those of unknown quality or troubleshoot to the component level after power
is disconnected to the device under test.
