[Amps] HP noise figure meters

[David Kirkby]

I was going to post this on moon-net (where the S/N is generallly 
higher), but the messages keep boucing for me.
	
Can anyone who has used either (or preferably both) of the HP 8970A and
8970B noise figure meters comment on them. I'm particularly keen to know
of the advantages of the B, as it's a lot more expensive than the A.
