The 2250A is a Phase Angle Voltmeter (PAV) that offers advanced measurement capabilities. Key features and capabilities include:

High Accuracy and Compact Design:

Provides high accuracy in a smaller, lighter package compared to existing designs. Measurement Capabilities:

Measures Total, Fundamental, Harmonics, In-phase, Quadrature, Frequency, Total Harmonic Distortion (THD), Ratio, and Phase angle simultaneously. Isolated inputs enable null, ratio, and gain measurements. Enhanced User Interface:

Features a high-resolution touchscreen, front panel USB mouse interface, and a multipurpose increment/setup knob for local programming. Large display (2.3" x 5.8") capable of showing up to 16 parameters at once. Includes a sensitive analog null meter as a standard feature. Programming and Connectivity:

Fully programmable with fast settling times. Connectivity options include Ethernet, USB, and IEEE-488. Versatile and Legacy-Compatible:

Supports LVDT (Linear Variable Differential Transformer) and RVDT (Rotary Variable Differential Transformer) measurement capabilities. Provides independent front and rear panel connections. Acts as a replacement for legacy NAI PAV models including 2250, 2251, 225, 321, and 213C. Optional internal 6VA reference available. Advanced Signal Handling:

Offers up to 80 dB harmonic rejection. The 2250A leverages the latest DSP (Digital Signal Processing) and FPGA (Field Programmable Gate Array) technologies, simplifying and extending the functionalities of prior models. It is designed to provide more accurate measurements with improved settling times and energy efficiency, making it a reliable tool for advanced electronic testing and measurements .
