North Atlantic 214C-S-1218

The North Atlantic 214C-S-1218 is a solid-state Phase Angle Voltmeter delivering precision AC signal analysis across aerospace, defense, industrial, and laboratory environments. This benchtop instrument provides direct readings of total voltage, fundamental voltage, in-phase voltage, quadrature voltage, and phase angle with ±2% full scale accuracy on voltage and ±1° phase dial accuracy. Both signal and reference isolation are integrated into the design.

– Technical Specifications

• Voltage Measurement Range: 300 µV to 300 V across 13 selectable ranges
• Voltage Accuracy: ±2% full scale
• Phase Angle Accuracy: ±1° (phase dial)
• Phase Sensitive Bandwidth: ±5%
• Operating Frequency (general): 10 Hz to 100 kHz
• Operating Frequency (phase-sensitive with modules): 30 Hz to 20 kHz
• Signal Input Voltage Limit (transformer mode): 0.75f (where f = signal frequency in Hertz)

– Key Features

• Plug-in, field-changeable modules enable phase-sensitive operation at 1, 2, 3, or 4 selectable frequencies
• Single rear-panel adjustment simplifies module recalibration
• Dual isolation (signal and reference) eliminates ground loop issues
• 13 voltage ranges provide measurement flexibility from microvolts to hundreds of volts
• Simultaneous quadrature and in-phase voltage decomposition

– Typical Applications

Testing, calibration, and simulation of synchro and resolver-based systems in precision AC environments. Suitable for demanding signal analysis where phase relationship and harmonic content require independent measurement.

– Compatibility & Integration

Designed for modular frequency selection through field-changeable plug-in modules. Accepts recalibration via simplified rear-panel procedures without requiring full instrument service.
