Hello,

I have been trying to figure out what type of tranformer I need to step down the voltage of a signal so that I can measure it using a microcontroller. I've been searching for a while now and there are just so many options and I just dont know enough about transformers besides power system ones to figure out what I need.

The signal ranges from 25-800V, max 50W and is a damped sine wave. The frequency is at 1Mhz and is pulsed. So the characteristics I need to measure the peak amplitude and the time the pulse is on and the time that it is off. I think I need a signal transformer but I am really not sure. Any insight would be greatly appreciated. Thanks!

you can do voltage divider by using simple resistors connected serially , but dont forget to put compensation capacitors to compensate capacitance of input stage to that divider . Have a look to how the voltage division by 10 or 100 is done in scope probes .
 

plz send oscope input divider circuit schematic.(or DVM)
