MEASUREMENTS CORPORATION Standard Signal Generator Model 80-C

Circa 1949

A precision laboratory instrument used for generating highly accurate radio frequency (RF) signals.

Use Cases:

• Telecommunications Facilities: Used in large fleet radio maintenance shops for police and fire departments.

• Industrial Labs: Employed in production lines and research facilities for evaluating RF components.

• Radio Repair: Widely used by HAM radio enthusiasts and professional technicians for vintage tube radio and television repair.

This instrument provides standard RF signals with precisely known frequency and amplitude. 

• Laboratory Standard: Primarily designed for high-accuracy lab work.

• Testing & Calibration: Used for production testing and field maintenance of communications, video, and radar equipment.

• Modulation Analysis: It can produce sine-wave amplitude modulation (AM) and pulse modulation for simulating radar signals.

Historical Significance:

• Precision Engineering: At its release, it was a "gold standard" for stability and accuracy, featuring a hand-calibrated frequency scale for certain ranges.

• Technological Bridge: It used a unique mechanical coupling principle for its output attenuator and a vacuum-tube-based oscillator housed in a specialized shielded compartment.
