I do not have great equipment to do the measurement but it is at least this
good at 10 MHz as measured on one of my 8642As. I can't measure phase noise
at 30 or 100 MHz.

Offset (Hz) 10 20 50 100 200 500 1,000 2,000 5,000 10,000 20,000 50,000
100,000 1,000,000
Phase Noise (dBc/Hz) -96.9 -103.0 -106.9 -109.7 -117.7 -128.4 -136.4 -140.1
-143.1 -144.9 -145.6 -145.7 -146.2 -146.6
