Of the cheap arb generators non I know has usable PC software for the arb function. Of course you can try your luck, and maybe you happen to belong to those for which such software not only installs without problems, but provides the features you need and happens to successfully communicate with the instrument. If that happens, also consider playing the lottery

If not, prepare to write your own software. The good news is you can customize your software to the task at hand. The bad news, depending on the support or absent of support you get with the arb generator, this can be a hellish task. Look for programming documentation, libraries, drivers, etc.
Quality manufacturers typically have usable software. E.g. Tek with ArbExpress. HP went through a number of product names, BenchLink Arb, IntuiLink, and their latest is BenchVue. I haven't seen it, but people complained it has some restrictions similar to trial software.
TTi has something, too. It looks promising, but I never worked with it. Keithley also has something. So does Hameg. I seriously can't remember if I ever touched those softwares.
An exception within the quality manufacturers might be LeCroy. Some what they sell is rebadged Atten/Siglent stuff. I have no idea if they fixed the Atten/Siglent PC software, but I doubt it.
Anyhow, even with the quality manufacturers it can happen that you need to write your own software. Your task might just be too exotic, or you happen to run into a bug in a manufacturer's software. And there is the big operating-system obsolescence issues. With any software, quality manufacturer or not, the next OS version, update, patch or whatever can kill the software. If you don't get an update from the manufacturer you are back to square one, write your own software. Or buy a new arb generator ...
