To do this, I have tried measuring resistors but I seem not to get the right results. My supervisor then recommended using a function generator to do the calibration. I have measured certain noise voltages (0.1Vpp, 0.5Vpp and 1.0Vpp). However, I don't seem to understand how these relate.

My question is this. what does the noise spectral density measured from the function generator noise output translate to? A resistance? How do I compare and what might I compare with.

P.S. I intended to compare the measured spectral densities to certain resistances as calculated from the Johnson noise equation. Is this correct??

Thank you
