Dont know how this graph from the oscilloscope is scaled
 I do not know how this is scaled. The circuit is a forward biased diode with a resistor in series, hooked up to a voltage source of a sin wave with the voltage peak at 1.3v. The graph is the voltage across the resistor with respect to the diode. Last edited by Waffles; 02-08-2010 at 01:01 AM.

It's impossible to tell. The color coding implies that the vertical amplifier's gain is at 200 mV per division, but you don't know if the input is being attenuated through a probe or not. The best you can probably do is assume it's 200 mV per division and be cognizant that you might be off by a factor of 10.
