My company designs wideband active CTLE amplifiers used in high speed serdes channel application. I have an N5222A VNA and am wondering if I can measure the thermal noise output of this amplifier. I would like to then take this power spectral plot and integrate and calculate the RMS value and use this in signal integrity simulations assuming a Gaussian PDF. The amplifier I'm talking about has a 100Ohm differential 50Ohm single ended input and output impedance. I've seen some people use only KTB as the noise and some other use 4*R*KTB.
Any suggestions on how to do this properly or if possible on my VNA?
