The General Radio 1633-A Incremental Inductance Bridge was introduced in 1968 Catalog T and remained available through Catalog 1978.
The Type 1633-A is specifically designed for the measurement of iron-core inductors such as transformers, chokes and other coils with ferromagnetic cores. It's built in detector which is selective at nine specific frequencies is designed with a narrow bandwidth reducing harmonics generated in the unknown. The 1633-A requires an external generator with the power required to saturate the unknown to the desired level. The Types 1265-A DC Power Supply and 1308-A Audio Oscillator combination generator combination along with the 1633-A make up the 1630-AV Inductance Measuring Assembly.
Specifications
- Accuracy:
- Inductance: ±1% of reading or 0.1% of full scale.
- Resistance: ±2% of reading or 0.1% of full scale.
- Frequency Range:
- Internal Detector: accurate to ±1%, 50, 60, 100, 120, 400, and 800 Hz, and 1, 10, and 15.75 kHz.
- External Detector: external detectors can be used at any frequency between 20 Hz and 20 kHz.
- External Generator 20 Hz to 20 kHz.
