Looks like you're right, my mistake. That probably explains the price difference....
cncjerry:
I paid $750 fo my R3131a with TG. Perfect condition.

I've been looking on eBay for a spectrum analyzer for several months, finding one with a tracking generator for under $2,000 was almost impossible. Finally I decided to buy a new Siglent, I bought the tracking generator license and with the EEVblog discount I spent about $1500. Having said that, I love vintage equipment and have some HP and Agilent gear.
Thanks for a great topic and your research efforts.

HP 8562A
range 1 KHz - 22 GHz (plus reasonably easy to find 11971 external mixers)
span zero, 2.5 Khz to full (but broken into a low and high band at 2.75 GHz)
RBW 100 Hz to 1 MHz
$1-2k in good condition.
Resolution bandwidth doesn't go as low as the rackmount beasts of the era, but is portable (in a 1980s sense).
