  • Notes

  • Precision Bridge B331

    An auto-balance bridge with two meters which provides simultaneous reading of the in-phase and quadrature terms of any component or complex impedance.

    The internal source operates at 1 kHz, but operation can be from 50 Hz to 20 kHz using external equipment.

    Overall measurement capability at 1 kHz is .0001 pF to 0.25 pF,
    1 pΩ-1  to 1 kΩ-1, 1 mΩ to 1 TΩ and 100 nH to 250 MH.

    All the exact characteristics are contained in the attached file, which describes the device.
