Well,there's the TEK 1401 or 1401A,that was designed to connect to the 323
scope and had BW up to 500Mhz(can be used with other scopes,too).
Or there's a 7K mainframe(7603) and a 7L12 or 7L13 SA plug-in,which goes
10Khz-1.8Ghz.Or find a 2710,2712 portable SA,looks like a 2213 scope,goes
to IIRC,1 Khz-1.8Ghz.There's several HP analyzers available used,too,but I
don't know model numbers for HP. You need to peruse a few used Test
Equipment company catalogs. Google ought to turn up several.
There's also an inexpensive SA I've seen listing for about $1500 new,I
believe it comes from Taiwan,and marketed under several companies name
'brands'.I saw them in hobby electronics mags like Nuts&Volts.
SA's are not cheap.
