M SERIES - Low Duty Cycle/Single Switch Pulsers (Fall Time a Function of Load RC)
These pulsers will operate into dynamic impedances or capacitive loads. Typical applications include piezo-electric drivers, electric fields in aqueous solutions, electric fields in a vacuum, beam steering, ion drivers, laser modulators, gas tube drivers, etc. Max widths are for high impedance loads, duty ~1%:

C SERIES - High Duty Cycle, Drives Capacitive Loads with Fast Rise/Fall Times
These pulsers will operate into large capacitive loads with relatively fast rise and fall times. Main Switch charges load, Tail Biter discharges load. Pulsers may be ordered with baseline offsets, Load R > 500k, Duty > 50%. Pockels Cell Driver, beam steering, field enhancement, imaging, etc. Standard power supply 30 watts, larger supplies available and may be required to operate to switch rep rate limit.

F SERIES - Fast/Low Average Power/Single Switch/Dynamic Load Pulsers
Pulsers use a single planar triode switch: rise times ~50 to < 5 nanoseconds, duty cycle ~0.05%. Typical applications include: Time of Flight Mass Spectrometry, Pockels Effect Cell Driver, etc. Maximum pulse amplitude, current and duty cycle is a function of load. Standard high voltage supply 60 watts, larger supplies available.
