3 meters length high voltage output coaxial cables for NPG pulse generators, other lengths are available on request

NPG series nanosecond pulse generators are designed for laboratory or industrial applications. They are suitable for 24/7 maintenance-free operation. NPG generators have a user-friendly and simple interface that eliminates possible operation errors which may lead to damage to the generator. They can work with any type of load including short or open load. Nanosecond pulse generators have over-temperature and over-frequency protection. The last is useful for external triggering operation mode. In case of overheating the generator will return to normal operation automatically after a few minutes of idle operation when the circuit components temperature reduces down to the safe level. Breakdown in the load does not lead to damage to the generator because of the reliable protection system. Please follow strictly the User Manual recommendations and contact Megaimpulse Ltd. in case of any question.
