I need a kinda oscillator to create impulses to drive transistor as a switch.
(0,33v+) amperage do not need to be hight...

Can i get it from USB and where i can get a program.

I need very universal frequency impulses 100 Hz to Mz.

I need to regulate both lengths.

Can it be done by this way and where i can start. I now a little bit basic C language.

Added after 3 hours:

Can i get this signal from USB port after all ?
 

USB Signal

The usb port has four connections, +5Volts at up to 500mA, GROUND and 2 high speed low voltage differential signal lines. You could not do this with a direct connection to the usb port.
The only way to do it would be to use a Micro with an inbuilt usb interface programed to output the pulses. Microchip have pic chips that could do this.
Check out microchip usb examples.
