VHF Signal Generator

Information

The Model 608A Signal Generator is a general purpose laboratory Generator covering the 10 to 500 megacycle band. Both the frequency and output are calibrated. Internal modulation at either of two fixed frequencies is provided. The instrument may also be modulated from external sources of sine waves or pulses. The Model 608A may be used for measuring gains selectivity or image rejection of receivers, IF and broad band amplifiers. The high output voltage (1 volt into a 50 ohms load) of the Generator is suitable for driving bridges, slotted lines, transmission lines, antennas, and Filter networks.

Information

Service Notes This Service Note contains information necessary for replacing and recalibrating the output attenuator in the 608A/B/C/D/E/F Signal Generators. The procedure is described for each model, using the appropriate replacement attenuator. This Service Note outlines the procedure for modifying the Model 608C.D VHF Signal Generators for regulated DC filament operation of the RF circuits. The original multivibrator filament Power supply in Some cases caused ripple on the output RF signal from the generator. The DC filament supply prevents this from happening.
