ramp generators

Ramp Generator
I need a circuit design for a ramp generator. The ramp generator circuit that I'm looking for is a 1khz ramp generator capable of + to -50 v at 50m using a microprocessor with digital to analogue converter and output reconstruction filter followed by a high voltage operational amplifier. The generator is going to be used for RFA(retarding field analysers) on plasmas.

THANK YOU FOR YOUR ANTICIPATED COOPERATION

This forum is Eng-Tips, not free engineering design. Maybe someone will post a link to some sample circuits online but you really need to do some research and engineering and then come back and ask for help when you have a specific problem.

For flexibility and low price, us a RIGOL DG1022. Everything you need in a cost-effective package. Then go to a company like KEPCO for the power part. Two standard devices and an RG58 to go between. Simple!
