General Radio 516-C
1932
- Radio Frequency Bridge
RF impedance bridge used for LF and AM transmission measurements.
Resistance range: 0.1 ohm to 1 ohms.
Power range: 0.05% to 3% at 1Mc.
Frequency range: 500Kc to 5000Kc with supplied output transformer.
Accuracy: direct reading bridge, ± 5μf or ± 1% at 1Mc for capacity measurements, ± 0.2 Ω or ± 2% for resistance and ± 0.001 or ± 5% for power factor.
In 1915, Melville Eastham and Kerro Luscomb form the General Radio Co., in Cambridge (USA).
The company distinguished itself for the manufacture of electronic instruments, test equipment, standard precision measurement equipment.
