These two plots have 3dB difference.
Latter, "pnoise" is SSB SideBand Noise.
Former, "pnoise jitter" is twice of latter.
Latter, "pnoise" is small signal mixing noise, that is, sideband noise which include both AM and PM noise.
Former, "pnoise jitter" is phase noise.
Agilent GoldenGate give same result as "pnoise jitter" and as another results, there are "side_band_left" and "side_band_right" which are same as "pnoise".
