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.
