Test-Signal Generator
Information
The Type 604-8’'’’Test-Signal Generator is a general purpose
instrument designed for use at high frequencies. By means of
easily accessible Plug-In coils, it covers a.frequency range
of from
3 to 100 megacycles (100 to 3 meters). It is designed to
have the widest possible application in the measurement of
receiver characteristics and transmitter field strength.
Additional ooils can be furnished to extend the range
downward to 300 kc. Eight additional coils are necessary to
cover this range.
The test-signal Generator is suitable for determining the
sensitivity of high- frequency radio receivers and, when
modulated by an external Oscillator, it may be used in
measuring over-all fidelity characteristics. When used in
connection with a radio receiver, an output meter, and an
antenna of known characteristics, it can
be used in the measurement of field intensity.
