What we are trying to do is generate a SINGLE positive pulse (positive 1/2 of a square wave from 0 to +5 volts) with the NI 5402 function generator on a PXI chassis. This is then put into a pulse amplifier, essentially a switch with a FET output, where we can vary the pulse amplitude from +5 to +28 Volts, and has the capability to drive into a load drawing from 2 to 5 amps. This is to simulate a F-16 Fighter Aircraft weapons system output that sets off squibs (small electro-explosive devices [explosive bolts] EED's) that detach bombs and missiles from the fighters wing pylons and launcher rails.
I have done this in the past with our older ATE using a HP/Agilent 33120A Function/Arbitrary Waveform Generator with the burst mode & a burst count of 1 (one), and a square waveform set to 0 to +5 Volts and a frequency of either 45 or 21 Hertz to control the pulse width.
We need 2 different pulse widths, 11mS for an EED-1 (+28V @ 2.5A) and 23mS for an EED-2 (+28V @ 4.5A).
Any suggestions on how we could simply do this???
