The only obvious problem that I noted on a quick test using the scope's 1KHz probe calibration square wave was that, in the Long Memory Capture, there is a large impulse-like discontinuity between each sample chunk. It looks like the DS2000 scope wants total number of samples to be a 10x multiple of 1.4 instead of the DS1000's 10x multiple of 1.2.

Can you through the ultrasigma control center send the following: WAV:START 1;:WAV:STOP 100;:WAV:DATA?
and paste me the result?

Edit:
The result changes when command is repeated:

Can you try this Version?:
Rigol V2.2.1:

Same issues. The first time I power up your program it works ok (1.2 Mpts). Also on 12 Mpts. There are a few glitches in the captured buffer but probably not enough to upset the FFT calculation.
But if I then try 24 Mpts I only get a flat line in the buffer window, and nothing in the FFT window. And then the 12 and 1.2 Mpts captures produce the same errors as can be seen on my previous screenshots (hickups in the buffer window, and FFT way off).
Screencapture still does not work. And after I try a screencapture the realtime display acts funny. Have to enable/diable it a few times for it to start again.
Also the scope's screen is flashing errors like crazy (all versions of them)
I have to restart both the scope and the program to get them to play nice again (but then only at 1.2 and 12 Mpts)

I am just curious if you guys thank that this could replace the need to purchase an actual SA?
I have a DS1074z, and I need to maybe check some filter responses, and maybe look at RFI or such stuff, or even look for harmonics on a transmitter.
I have almost every piece of gear I ever have told myself I needed, except for an SA because they are soooo expensive compared to most other gear.
So, for a hobbyist can this replace the need for a SA for mostly simple stuff when combined with a good signal generator, and a DS10xxZ scope?

Up to a point: yes. If you look at my comparison between the DSA815 and the FFT analysis you can see that up to say 3 MHz and -50dBm they are almost exactly the same. But further down in amplitude they begin to differ somewhat.
So i think that is useable as a SA substitute to possibly a few tens of MHz (remember the scope's BW is only 100 MHz and de sampling rate "only" 1GSa/s). And signals below say -50 dBm are also under suspicion. The scope's AD converters are only 8 bits, and by massively oversampling (say 12 to 25 MPts) you can up the dynamic range to possibly a practical 12 bits (I'm guessing here but the -70 dBm noisefloor of the FFT's seem to suggest this).
A real SA goes to at least 1.5 GHz (as my DSA815) and has a much larger dynamic range. the DANL is -130 dBm for the 815....
