1632-A

The General Radio 1632-A Inductance Bridge was introduced in 1963 Catalog R and remained available through Catalog 1974.

The Type 1632-A inductance bridge is based on the Owen bridge circuit at audio frequencies. The decade controls for "G" and "L" display their values with decimals in a series of vertical windows speeding up the measurement. The recommended generator is 1311-A and detector 1232-A which in combination make up the Type 1660-A Inductance Measurement System.

Specifications

• Inductance Range: 0.0001 μH to 1111 H.
• Conductance: 0.0001 μ℧ to 1111 ℧.
• Inductance Accuracy: ±0.1%, direct-reading. Accuracy is reduced at the extremes of inductance, Q, and frequency ranges.
• Conductance Accuracy: ±1% direct-reading accuracy. Accuracy is reduced at the extremes of the Land G decades, Q, and frequency.
