signal generator advice
nctnico:
There is also the UNI-T UTG932E which is super cheap and powered from 5V. But I wouldn't buy it before looking at a review showing the custom waveform generation process and decide it is useful.

I have used a Python script to create a digital waveform loaded in my Owon XDG 2035, if it's of any help : https://www.eevblog.com/forum/testgear/owon-xdg2000-arbitrary-waveform-generator/msg5422235/#msg5422235
The thing costs 289€ VAT excl. : https://www.owontechnology.eu/product/1398979/owon-xdg2035-35mhz-2-ch-arbitrary-waveform-generator

Is powered 15vdc?

yes, you can run those on powerbanks... it just need to support PD15V (power delivery) and a powerbank with high wattage support (fx +45W variant)
They consume quite a bit (35w) and they take over a minute to start up and their fan is quite annoying.
The benefits are the big touch screen, quite newly released model fast risetimes (3ns), with a UI that Rigol also seems to implement on their highter tier sig-gens like DG5000PRO.
DG-800PRO & DG-900PRO have a portfolio of waveforms that seems to be relevant in automotive, though others do have more, I'm not familiar with automotive electronic repair, and which could be handy for your work, but you can see the inbuilt ones below.

The Uni-T 932/962 can have only one user generated waveform uploaded into volatile memory at a time. Switch off and it is gone until you connect to computer and upload again.

Yes, very nice and features that still make me want to consider it for my own purchase, over anything from Siglent in this price range. But haven't you yourself written in other threads here that the stability of that UI isn't great? And that you see "odd" behaviour sometimes? (My apologies, if I have confused you with another contributor).
Besides which, the inexplicable absence of the ability to create a single-shot, manually triggered pulse which can exploit that (variable) rise-time makes it pointless for my own requirements.
To my original point on this thread, and the OP's question of recommendation, if I had any confidence remaining in Rigol to eventually/ever fix any of these issues then I would have purchased in last month when Rigol had a sale on them.
