1021-A

The General Radio 1021-A is part of a series of Standard Signal Generators introduced in 1951 Catalog N. It remained available through Catalog S 1965.

Frequency range is dependent on the oscillator type installed. It has internal modulation at 1000 Hz as well as provision for external modulation. The panel reads output voltage or modulation percentage.
