Grounding Options

• Floating output (cannot be grounded): This option is the standard and strongly recommend as it reduces electromagnetic noise, makes voltage measurements cleaner, and produces the fastest rise times.
• Positive referenced output: For applications that require grounded pulsers, the output can be internally grounded at the factory so that the pulser produces a positive voltage.
• Negative referenced output: For applications that require grounded pulsers, the output can be internally grounded at the factory so that the pulser produces a negative voltage.

Internal Parallel Resistance (R_p)

• High impedance: A high internal resistance is optimized for power transfer to resistive loads and sparks and dissipates less power.
• Low impedance: A low internal resistance is optimized for producing fast fall times on capacitive loads (e.g. dielectric barrier discharges).

EHT nanosecond pulsers are used in a wide range of academic research:
