dear sir,
i want to make a pulse power circuit requiring features
are given below. I'll be very much thankful to you if
you kindly inform me regrading this.
Pulse power supply:

Input trig. --> TTL (preferebly with optical isolation inbuilt into
the PFN system itself.
Powersupplies --> Preferebly it should be a part of PFN.

O/P Current --> 1 Adc to 2000 Adc or above ( or whatever maximum
amplitude possible to be able to vary contineously)
O/P Impedence --> Load 1) R=50 ohm & L=250 nH.
Load 2) L=6 microHenry & R= any value which you would
suggest for best results.
O/P Rise time & Fall time: for load 1) > ~ 100 ns or even less.
for load 2) > ~ 500ns or whatever best is
O/P pulse width --> To be able to continuously vary pulse width from 50
ns to about 10 microsec for both kinds of loads.
O/P over/undershoot > preferebly less than 5%.
O/P duty cycle = 1 Hz
