High Voltage Test Interface for Dielectric, Conductivity and Impedance Two-Electrode Spectroscopy for the Alpha-A Modular Measurement System

The HVB 1000 extension test interface for the Alpha-A modular measurement system features dielectric, conductivity, impedance 2 electrode spectroscopy at dc and / or ac voltages up to ±500 Vp. 

Like all Alpha-A test interfaces, HVB 1000 has high general purpose performance but is optimized for for broadband high voltage measurements of low-loss dielectrics.

HVB 1000 is especially recommended for dielectrics, semiconductors or electronic components at high AC and / or DC voltages for

For material measurements, operation with the Novocontrol High Voltage Sample Cell is recommended.
