The PAV-4 series of Phase Angle Voltmeter provides complete capability for measurement of the amplitude and phase characteristics of AC voltages. Wide frequency coverage (30 Hz to 300kHz), large dynamic range (300 µV to 300 V), harmonic filtering and high input impedance (10 megohms) with or without input isolation are standard.

Mainframe and plug-ins of the PAV-4 series are designed for various types of applications.
The PAV-4B has signal and reference inputs which are isolated from ground. The frequency range is 300Hz to 300 kHz in the total mode.

NOTE: The above specifications are for the PAV-4B, Not 4BR - Additional specifications available upon request.

This PAV includes the MF-1 Plug-in with 400 Hz & 54,000 Hz filters.

It may not win a beauty contest, but it works great.
