Phase Angle Voltmeter, High Accuracy

Model Instrument 2250

NAI’s 2250 Phase Angle Voltmeter employs a microprocessor-based design using Fast-Fourier Transform techniques that combine many of the capabilities of today’s network/waveform analyzers in a digital analyzing voltmeter configuration.

Designed for the Synchro/Resolver and LVDT/RVDT marketplace, this instrument accurately makes measurements of phase angle, in-phase, quadrature, fundamental, and total, as well as impedance, power, and harmonics. Isolated inputs allow null, ratio, and gain measurements of key parameters. A reference phase offset facilitates bridging measurements. A sensitive null meter is included for precise nulling. The 2250 is ideally suited for defense, industrial, and commercial applications.

Typical Applications:

  • Automatic test equipment (ATE)
  • Transformer ratio & phase tests
  • Amplifier gain & phase
  • Phase-sensitive null detection
  • Network transfer function analysis
  • Input/output impedance testing
  • Wide-band, high sensitivity voltage measurements
  • Attenuator linearity testing
  • Harmonic analysis
  • Accelerometer testing
  • Phase angle measurements
  • Synchro/Resolver transducer testing
  • LVDT/RVDT testing
  • Filter testing:
    • Insertion loss
    • Phase shift measurement of power factors
    • Complex impedance phasing of servo motors & servos

For new applications, please refer to NAI's 2250A, the recommended replacement for the 2250.
