Rigol DG1022 vs. Modern Budget Signal Generators
DoorVb:
Hello everyone,
I've been in the market for a basic signal generator for a while now. I've been considering cheap options like the Feeltech or Owon models, typically around the €150 price range.
Yesterday, I came across a Rigol DG1022 listed for auction on a local marketplace, starting at €150.
After doing some research, the Rigol seems like a solid choice that more than meets my needs frequency- and spec-wise. However, I noticed it's quite an ancient model. Some reddit posts from almost a decade ago calling it 'rather old'. so I'm left wondering:
* Have modern budget signal generators surpassed the DG1022 in terms of specs, ease of use, or overall quality?
* Would it still be a good buy today, given its age?I'd appreciate any advice or insights you might have!
Thanks in advance.

Hello,
Batronix offers the UNI-T UTG932E for € 141.61. It is better than the Rigol DG1022 in almost all respects. The only difference is that the NI-T UTG932E only has a maximum amplitude of 10 Vpp in 50 ohms up to 10 MHz.
However, the second channel of the Rigol DG1022 is very limited.
The Rigol DG1022 is not bad, but 150 € is way too much these days.
Best regards

I wouldn't classify the DG1022 as "ancient", more like an "older model". If your needs are truly "basic", then whatever you choose will probably be fine, but you didn't mention any specific use cases or requirements.
Many hobbyists select older gear for various reasons, such as nostalgia, more direct interaction, performance per dollar, etc.
Side note, typically the DG1022 would be called a function or (arbitrary) waveform generator, not a signal generator. When shopping for older AWGs, be sure you can actually get the software working necessary to build or capture the waveform and send it to the generator.
I might suggest getting something quite a bit less expensive, then upgrading later once you know what you need.
Or if you can stretch your budget, the Rigol DG1022Z or DG811 might be reasonable options. They can both be "upgraded" to higher performance levels following instructions here on the forums.

Alright, that UNI-T model costs €120 in Belgium. So I think it will suit me fine! I don't know why Rigol keeps their old stuff so expensive...
Many thanks!

Imo, it is best to define what is important to you before you buy.
Example: UTG932E has slightly better THD than Feeltech FY6900, but the FY6900 has more than twice as fast a rise time as the Uni-T.
A device is sometimes better and worse at the same time, depending on which characteristic you look at.
