General Radio Company
General Radio Type 805-C Standard Signal Generator
This is perhaps the ultimate in tubed signal generators for the AM broadcast and shortwave bands, and at 117.5 pounds must be one of the heaviest. It covers 16 kHz to 50 MHz in seven ranges. Frequency calibration is ±1%, and, after warm-up, frequency drift is less than ±0.1% over five hours. The output meter and attenuator provide continuously adjustable output from 0.1 V to 2 V. Metered AM modulation can come from the internal 400 Hz and 1 kHz oscillators, or from an external high-power oscillator. Because the the modulated stage is a buffer, rather than the oscillator, modulation up to 100% can be attained with negligible incidental frequency modulation in the output.
