Hi Sparky
I know that people have concerns over Rigol FW and to an extent I would agree with some other models, genuinely have not had any gripes or obvious bugs with the RSA (different for the MSO5000 I might add, but its still a good piece imho).
Yesterday I engaged the unit twice once one with a Rb audio studio clock repair and the other for a wifi issue at 2.415Ghz, identifying in stock SA mode and really go deep with real time mode to identify the spurious signals for a suspect router
Not a Rigol fanboy either, I have pieces from Siglent, Keysight, Marconi, HP and Agilent all of which have a useful place in my lab.
Others may feel different
Last week I purchased a the Siglent VNA unit and with the new FW it makes a solid basic VNA that performs some positive features that I require, towards the end of the year I will obtain a greater BW VNA but for the outlay its a nice piece and the basic SA is fine.
The RSA 3030 is one of the pieces that has slipped under the radar possibly due to its price, out of the DIY bracket but not taken seriously enough by the SME's or educational facilities. However Tv84 must take the credit for his exceptional tenacity with coding and understanding the structures of how various manufacturers go about their coding operations, so his modesty of being the sorcerers apprentice is a little misleading
Having various manufacturers equipment side by side I find the RSA easy to use compared to say the Keysight (which I find clunky) however overall the balance is nice and takes a few days to competently fly.
These units are worth checking out if you are in the market for a quality SA with a lot of capabilities but as always do compare with others of the same abilities and live with them for a good couple of weeks before deciding to part with your funds.
