HVB 300

NOVOCONTROL
Safe High Voltage Measurements
Novocontrol impedance analyzers, renownedfor highest accuracy and precision, deliver top
performance in various applications, e.g., mate­rials science, macromolecular research, semi­
conductor development, analysis of chemical
reactions, and many more. The investigation ofnon­linear properties adds the requirement ofhigh electric fields applied to the materials un­
der test. The use of commercial high voltage
amplifiers in combination with a highly sensitive
measuring instrument like a Novocontrol impe­
dance analyzer, however, is troublesome:chances are high that the measurement system
might be damaged or even destroyed. It is,therefore, imperative to apply particular techni­ques that achieve protection against potential
high voltage input signals.

HVB 300
The risk of severe instrument damages duringhigh­voltage experiments is easily overcome by
the application of the high voltage extension
HVB 300. In this device, a specially designed
high voltage input amplifier ensures continuous
and reliable operation in high voltage mode.
The HVB 300 is designed as a test interface for
the Novocontrol Technologies advanced fre­quency analyzer ALPHA­A, which, in turn, is con­trolled by a computer typically running theNovocontrol WinDETA software. The software
controls all functions of the test interface, resul­ting in a turnkey integrated solution for high­vol­tage dielectric and impedance measurements,including calibration and automatic reference
capacitor selection for ultimate measuring ac­
curacy. The HVB 300 is equipped with interlock
protection and safe high­voltage (SHV)
connectors.
