Hi all,
I am looking for a good circuit, which can create an arbitrary wave form with microsec precision, and the maximum peak voltage should be 40-50 volt. For arbitrary wave form, I think it must have an interface to PC. Could you give a guide on this problem?
Thank you so much!
PS: Now I have a Agilent 33120A 15MHz, but it can not reach out of 10volts. Should I amplify it? and which schematic is a good one?
 

How if you use DDS chips and make some amplification to match your voltage level
 

Using a commercial HV/power OP seems to be the most easy solution. See

Thank you very much. I think your solution is the best.
I want to ask another question
http://datasheet.digchip.com/096/096-51260-MP400.pdf
In the above datasheet, I see that the OpAmp has 350 V/μS Slew Rate (very high) but a 200 kHz Power Bandwidth (not very high). As I think, when Slew Rate is high, system has fast response to input, therefore Bandwidth is also high. But I think it's not really true in this case. (I am not sure of having a clear understanding of Slew Rate and bandwidth here)
My application requires pulses in microsecond. Therefore, the frequency should be in MHz, I think. So, in this case, can MP400 be used for my application?
 

350 V/μS isn't a high slew rate with 350 V output. You have to specify both, slew rate and bandwidth.
