2250A

Phase Angle Voltmeter, Industry Standard

NAI's 2250A Phase Angle Voltmeter is the most accurate and versatile AC measurement tool in the Synchro/Resolver and LVDT/RVDT marketplace. Considered the industry standard and based on the latest DSP and FPGA technologies, the 2250A substantially extends and simplifies the capabilities of the legacy 2250 model.

This precision instrument measures total, fundamental, harmonics, in-phase, quadrature, frequency, THD, ratio, and phase angle, and displays all of these measurements at the same time. The isolated inputs enable null, ratio, and gain measurements. This instrument is ideally suited for defense, commercial aerospace, and industrial 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
