One of the most important applications for the 1422 is in ac bridge measurements, either as a built-in standard or as an external standard for substitution measurements.
The IET Labs, GenRad 1422 is available in a variety of ranges, terminal configurations, and scale arrangements to permit selection of precisely the required characteristics.
- Range as low as 0.002pF and as high as 1150pF (depending on model)
- Stability: better than 0.02% full scale per year
- Settable to 40 ppm
- Low temperature coefficient, low losses
- Wide selection to suit needs
