The 732A DC Reference Standard is a solid state, dV reference standard which provides significant performance improvements in stability, ruggedness, and transportability. Its 10V output offers better resolution, lower noise, and simpler operation than standard cells. The unit also includes outputs of 1.0 and 1.018 volts. Its stability of 0.5 ppm for 30 days provides the confidence necessary to calibrate high-performance instruments.
