The insulator used in the VD series probes has been upgraded to
Polypropylene. This gives these probes the maximum possible tracking
resistance and dielectric strength
About North Star High Voltage
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).
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
A major advance embodied in the design of our probes is the use of standard 50 ohm or 93 ohm coaxial cable to connect the probe to the oscilloscope or digitizer. Since standard cable is used, the probe can be placed some distance away from the recording instrument (standard units with 30 ft. cables are available) while retaining the wide bandwidth capability. The probe can be placed at the test device while the recording instrument is placed in a screened room, or in a low noise location far from the device.
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.
