Precision, Wide Bandwidth High Voltage Probes
Up to 300 kV

North Star High Voltage develops and manufactures high voltage probes which define the state of the art in high voltage measurements. We also develop and manufacture support circuits for closing tubes including Thyratrons and Ignitrons (Thyratron drivers and Ignitron drivers).

VD-200, VD-150, VD-100, and VD-60 Probes

North Star builds two main types of high voltage probes - the PVM series designed for portability, and wide bandwidth, and the free standing VD series designed for long life and accuracy. Both types of probes can be used with 1 Megohm input oscilloscopes (standard) or with meters of various input impedances (specify meter type when ordering). The probes are also available in "bare" versions for OEM applications. See more on High Voltage Probes.

Standard Cables & Long Cables Make Difficult Measurements Easy

Low temperature and voltage coefficient resistors and capacitors are used throughout the probe line to provide maximum measurement accuracy. The probe has a rugged nylon housing, and it is filled with dielectric oil for maximum high voltage stability.

Ignition & Thyratron Drivers

Our ignitron drivers are designed to operate at high current (>400 A) while providing high voltage (>2 kV) in a rugged metal package. Our thyratron drivers are available in styles with DC or pulsed preionization or without preionization.

The company came into being as the successor to North Star Research in high voltage probe and driver technology. North Star Research has been acquired by Ionatron which continues to make the other high quality, innovative, North Star products including pulse generators and DC accelerators.
