1001-A

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.

Specifications

• Frequency Range: 5 kHz to 50 MHz in 8 bands
• Accuracy: ±1% of reading
• Stability: Warmup drift ~0.25%, half the maximum drift reached in approximately 1½ hours
• Amplitude Modulation: 0 to 80%, continuously variable, indicated on the panel meter to ±10% of reading
• Modulation Frequency: 400 Hz internal, 20 Hz to 15 kHz external modulation
• Output Impedance: 10 Ω except at the 100 mV multiplier setting 50 Ω, 300 Ω at the 2 V output
