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 (1003-9705) 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.
