The General Radio 1001-A is a standard signal generator introduced in Catalog M (1951). It remained available through Catalog 1973.

The 1001-A covers a frequency range of 5 kHz to 50 MHz. It has a calibrated attenuator with output 0.1 μV to 200 mV, and also 2 V direct output.

The internal RF oscillator and turret band switch are removable for servicing. Inside the cabinet is a hex alignment tool for adjusting the oscillator turret coils.
