What is the simulation tool for measure?
In hspice, you can measure the noise for AC analyzer by add a AC source.
Noise Figure is a metric for measuring the Signal to Noise Ratio degradation, when Noise Power generally is the total noise per bandwidth at specific frequency.
So, better than using a Noise Figure Analyzer is to use a standard Spectrum Analyzer and measure the noise power at particular frequencies in dBm.
If you want to measure the carrier noise power at specific offset in dBc/Hz use the following formula:
Noise power[dBc/Hz] = Carrier power[dBm] – Noise power@Freq offset[dBm] – 10*LOG(RBW[Hz])
