1001-A

The General Radio 1001-A is a standard signal generator introduced in 1951 Catalog M and remained available through Catalog73. The 1001-A is a lab grade signal generator covering a frequency range 0f 5 kHz to 50 MHz. It has a calibrated attenuator with output 0.1 μV to 200 Mv also 2 V direct output. The internal RF oscillator and turret band switch are removable for servicing. Inside the cabinet is an alignment tool (hex) for adjusting the oscillator turret coils.

Specifications

• Frequency Range: 5 kHz to 50 MHz in 8 bands.
• Accuracy: ±1% of reading.
• Stability: Warmup drift is in the order of 0.25%. Half the maximum drift is 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 the 100 mV multiplier setting 50 Ω, 300 Ω at the 2 V output.
