1003

The General Radio 1003 Standard Signal Generator was introduced in 1968 Catalog N and remained available through Catalog 1978. The 1003 is a lab grade solid state signal generator covering 67 kHz to 80 MHZ in 10 bands. It does this with a precision oscillator covering 34 MHz to 80 MHz then using frequency dividers to produce the different frequency ranges. The model pictured below contains the options for motor driven frequency control and sweep function. It also has the calibrator option using three frequencies 1 MHz, 200 kHz, and 50 kHz.

Specifications

• Frequency Range: 67 kHz to 80 MHz in 10 ranges.
• Calibration Accuracy: ±0.25%, typically ±0.1%.
• Output Voltage: 0.05 μV to 3 V across 50 Ω.
• Source Impedance: 50 Ω ±10%.
• Modulation: 400 and 1000 Hz, ±0.5% AM; Provision for external modulation.
