HVB1000
High Voltage Test Interface for Dielectric, Conductivity and Impedance Two-Electrode Measurements 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
-
non-linear dielectric / impedance spectroscopy;
-
characterization of materials or components under stress;
-
extreme high impedance samples exceeding 1014 Ω.
For material measurements, operation with the Novocontrol High Voltage Sample Cell is recommended.
