The North Atlantic 321 Wideband Phase Angle Voltmeter is a completely solid state instrument, combing the ability to measure both phase angle and magnitude of compiled ac signals and vector components with respect to a reference input

And automatic gain control (AGC) circuit, in the reference channel, eliminates the necessity for manual adjustment of the proper level of operation. It accepts and controls signal levels from 150 mV to 150 V rms automatically.z

The reference channel isolation feature enable the reference input voltage to float with respect to the circuitry ground, maintaining its independent AGC action.
