Siglent SSA3000 plus or Rigol RSA3000 - which one is "best buy"
zrq:
Hi all, I'm actually considering the same question recently, but I'd like to ask from a different perspective. Which of SSA3021X plus or RSA3015N is newer? I'm considering buying one for use recently (but can be pulled off till the beginning of next year) while expecting moving to more advanced equipment (higher freq) in a few years and I may be physically moving to a new country too. So I would like to know which of them may have a higher resell value after some time (say 4 years). I tends to believe a newer model would be more future proof.

I'm like you, I'm looking for future proof, without crazy price of course (although this is relative...)
SSA3021X+ => I've got one, but I'm looking for smth "more" etc...
current price = 1.7kEur
interface = the screen, or thru your PC you have a copy of the screen (VNCviewer ; remote etc)
I'm looking for another SA because... when you go down the RBW, the SSA is slow
RSA3015N => I don't know this SA, thus no comment vs quality.
but,
price = 2.5kEur
RBW min = 10Hz (very high, "to me")
2days ago, as I'm looking for a better SA than the SSA3021X+, I googled... and read pages...
and oups ! => I end up to the web site of Aaronia (well-known producer of SA, but their product were too pricey for me in the past)
=> they just launched the "Eco" series !
for info, watch youtube vids / Aaronia SA... waouh !
to make it clearer => watch their brand new SA => https://aaronia.com/en/shop/spectrum-analyzer/real-time/compact-usb?serie=182
This one is a "basic" SA, with trackGen => https://aaronia.com/en/shop/spectrum-analyzer/real-time/compact-usb/spectran-v6-eco-150xa-6
price, incl. 20% VAT for hobbyist in EU => 4.2kEur
(apparently, dixit their forum, the preoreders got a nice rebate)
4.2kEur for this hardware... if you look at the specs => it is a bargain (RBW min = 0.062mHz !)
then => as it is a headless device (USB) => the interface is the software... and the "RTSA-Suite Pro" software is included into the price of the SSA (the headless box !)
=> I looked at this soft... => stunning !
To concluded vs Aaronia "Eco" series :
1. there is no topic dedicated to Aaronia SA in this part of the forum... it should exist ! :D
2. the specs of the Eco series hardware are miles away from any other product on the market (500GHz/s sweep time :D waouh !)
3. their soft is... an interface... but a bit more, isn't it ?... I let anyone to reply if I missed smth, but these features are miles away from any other SA on the market...
To concluded vs your sentence : "buy new is better".
Aaronia shows that you're right !
Last years, huge improvements were made vs EE hardware (FPGAs etc..). So then, anyone can look at the prices of used SA @ electrorent & Co => there are many old stuff, with no interface to PC (too old), RBW min way above 1Hz, 5-10-20kg the piece, sold at unbelievable prices vs this AAronia Eco series
Apparementy the lead time is quite long @6weeks... but it is future proof and a good asset to put your cash into as a hobyist.
Any comments is welcome to kick my a.. because I've seen the picture the other way around :-DD

Can I ask how well does the SSA3021X Plus demodulate ASK/FSK signals.
If I send a an modulated bitstream of about 50bits will it decode the signal and tell me what was sent?

hi,
no clue vs your question, that's out of my "spectrum" :-)
chrisb741:
According to the data sheet it < 10M symbols? / second
Not sure what that exactly means
