Nanosecond Pulser | 30 – 5000 W | Adjustable 5 – 25 kV, 20 – 250 ns, 1 – 100 kHz

The Nanosecond Pulse Generator (NSP) series by Eagle Harbor Technologies (EHT) is available in either low or high power variants. Low power units operate at 30 W, 60 W, and 120 W. High power pulsars operate at 1000 W, 3300 W, and 5000 W.

In a very user-friendly format, the three key output parameters of short pulses can be independently and continuously controlled by the user, on the front panel or by fiber-optic trigger. The range of adjustments are:

Adjusting these values gives the user excellent pulse control with high precision timing.

All units operate at a fast rise time of 20 ns. Dielectric capacitive loads vary from 0 to 100 A current output.

EHT NSPs achieve fast output repetition rates of ultra short high voltage pulses with continuously variable output pulse lengths. High voltage isolation is integrated into the design. The units can be controlled via a fibre optic gate.

A clean square wave form is produced, although the exact pulse shape depends on the load. Further, different pulse waveforms can be achieved by adding a magnetic compression stage.


Optionally, the units can be equipped with external pulse input capability, 1 MHz burst mode, and a pulse shaping output stage.

Note that the full range of values may not be available in the same unit, and that some settings may prevent others from reaching maximum.

The low power nano-second pulse generators are available in benchtop format, and the high power nano second pulsers are available in rackmount format.

Power is measured at the DC supply.

EHT NSPs are built with a floating output which cannot be grounded. EMI is decreased significantly by the floating output. The measurement of the output waveforms is also improved. This configuration is highly recommended unless there is a clear need to provide a grounded unit.

Custom built units are available to meet your load profiles.

EHT Nanosecond pulse generators are used for creating plasmas, dielectric barrier discharge, high voltage breakdown, fast capacitor charging, high power microwaves, particle accelerator modulators, tube replacement, pseudospark, light production, surface modification, drag reduction, as laser drivers, and in medical devices.

Product Spectrum

The EHT NSP range of nanosecond pulsers allows continuous and independent adjustment of voltage (kV), pulse repetition frequency (kHz), and pulse width PW (ns), apart from which it shares characteristics with fixed-value units from FID GmbH, particularly the FPG-N series, at a lower delivery lead time.

In the pulsed power category, Behlke Power Electronics GmbH make fast solid-state high voltage switches using MOSFET and IGBT technology.
