All instruments that were manufactured in Malaysia were originally built with 14-bit Digital IF assemblies. Instruments manufactured in the US that have Serial numbers US41513009 and later were also originally built with 14-bit Digital IF assemblies. Also, U.S. instruments that have serial numbers that start with US4136 and have the following suffixes were also originally built with 14-bit Digital IF assemblies: 2964, 2977, 2982, 2986, 2987, 2988, 2989, 2990, 2991, 2992, 2993, 2998, 3000, 3003, 3004, 3005, 3006, 3007. All other instruments with serial numbers US41362959 and prior were originally built with 12-bit digital IF assemblies. The date at which instruments started to be manufactured with the 14-bit Digital IF was approximately January 15, 2002.
You can also determine which digital IF assembly you have by looking at the Show System menu which is accessible by pressing the following key sequence on your instrument: . The part numbers of the major assemblies in the instrument will be given shown under this menu. The part numbers of the two revisions of the 14 bit Digital IF assembly are E4440-60025 and E4440-60195. The 12-bit Digital IF assembly is part number E4406-60006.
I'm missing the Advantest R3131 (320x240 monochrome display) and R3132 (640x480 color display) from the list. They are both not terribly expensive and not very heavy. Also an Advantest R3477 Signal Analyser may turn up on Ebay every now and then which is a PC based spectrum analyser with 1Hz RBW, 15.4GHz range and good performance at the price of being big and noisy.
HP 8650A 50hz-2.9ghz can be had very often in the $400 dollar range without the tracking generator.
Are you including portable versions in your list?
The Anritsu Sitemaster 331 variants (and occasionally 332) could be worth listing as they come up around this pricepoint. Maybe also the BK Precision 2650 series could also show up (though not the newer A variants). The R&S FSH3 series handheld units occasionally go for under $1000 US, but it's not super common. I don't think the R&S FSEA/FSIQ series benchtop analyzers typically sell under $1000, but you can find some under that needing repair or occasionally a working base model for not too much more.
the sitemaster 331 prices seem to be all over the place. $700 - $3000. what's up with that? there seem to be like 41,000 variants of the 331.
AFAIK you should be able to get an R3131 for much less than $1000 all day long. R3132 will take some haggling and the R3477 is probably closer to $2000. All these SAs work to at least 3GHz where with the Siglent SSA3021X you have to see if they remain hackable or not (and the firmware doesn't seem to be finished yet anyway). Still the Siglent SSA3021X is mighty tempting when spending around $1500 on a spectrum analyser.I'm missing the Advantest R3131 (320x240 monochrome display) and R3132 (640x480 color display) from the list.

AFAIK the last firmware update fixed the wonky results some people got from using the tracking generator but that also made the sweeps a lot slower (see: https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/msg1071366/#msg1071366 (https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/msg1071366/#msg1071366) ).

Yeah, I would focus on the 331D variant, it seems to be around that $1000 pricepoint pretty commonly and is usually sold with a color screen (which is actually an option on most 331 models... oddly). The pricing variation is probably partly due to the number of variants and options for them, but just the confusion around all of the versions - I think it's been in production in one model or another for quite some time.
Maybe the Anritsu MS2711 is worth adding too, seems to be sold around the same price.
looks like the S331D is an antenna analzyer only - only SWR, cable loss, TDR, etc. there is no spectrum analyzer feature in the documentation and there does not appear to be an SA option for the S331D.
HP 8650A 50hz-2.9ghz can be had very often in the $400 dollar range without the tracking generator.
i dont see any ebay auctions for hp 8650a. can you find any? if any are sold anymore, it looks extremely rare.
The display bezel started to turn yellow on my R3131A and I let it sit in hydrogen peroxide in the sun for a few hours and it cleared it all up. Nice and white now.You have to remove the screws/bolts for the connectors as well.
I have to change my battery before it runs out and I lose my features including the TG but I can't get the damn thing apart. I know it sounds silly, but there is something hung-up in it preventing the back cover from being removed.
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).
Topic: Rohde & Schwarz CMU200 (https://www.eevblog.com/forum/testgear/rohde-schwarz-cmu200/)Motherboard is either FMR5 or FMR6, it is not a standard motherboard.
Controller is a standard PC running MS-DOS. Motherboard is FMR6 with Award BIOS. CPU upgrades (https://www.eevblog.com/forum/testgear/rohde-schwarz-cmu200/50/) and SSD conversions (https://www.eevblog.com/forum/testgear/rohde-schwarz-cmu200/msg969646/#msg969646) are possible.
What would be addition to the comparison is to show if any of the spectrum analyzers listed have EMC options such as EMC bandwidths and Quasi peak etc etc.
Also, don't buy an 8568 or 8566 piecemeal or without cables.
I recently acquired HP8561E on ebay for $600. It's not trouble free, but mostly usable.
One interesting discovery is a thing called "AN/USM-489A" which is some kind of HP856X series. You can find schematic and other useful documentation for that.
http://radionerds.com/index.php/AN~USM-489 (http://radionerds.com/index.php/AN~USM-489)
Use "undesirable" options such as 75ohm input impedance as leverage for negotiating price.

One thing about R3465 is its a "Modulation" Spectrum Analyzer, i'm not entirely sure what is, but from the spec sheet http://www.testequipmenthq.com/datasheets/ADVANTEST-R3465-Datasheet.pdf (http://www.testequipmenthq.com/datasheets/ADVANTEST-R3465-Datasheet.pdf) it can do constellation and eye diagram plot and some other measurements in "Transient" mode (normal SA function is "CW" mode), i guess it has something with radio communication CDMA, GSM etc. i dont know how to use it (its there) and have no proper signal for it to test the function. so i believe it can add values to the SA functions.

its seem not, they are 3.6GHz model (not 26.5GHz).. and sellers got some rating... i got 13.2GHz Anritsu for half the price..Agilent/Keysight N9020-503 MXA are now showing up on ebay from chinese sellers for about $1800.There are two sitting on ebay for what seems like a bargin ($1800)for many months now. I would suggest caution here. If it seems to good to be true.............
