If you want to tinker and learn about the test gear, are on a very low budget, have plenty of time to spare, and are a masochist, then consider these waveform generators.
For what I consider not much more money - around $337.50 total after eevblog discount - you can buy
a Rigol DG1022Z from TEquiment and have it shipped to you for free. Then you will be able to:
1. Get a real warranty and return it if there's something wrong
2. Apply firmware updates when they are released
3. Not worry about power supplies frying you or the DUT
4. Get free AWG control software that runs on your PC
5. Be able to 'talk' to your AWG over LAN/USB using LXI
6. If you already own a Rigol scope like a DS1054Z, you can capture a waveform on the scope and then load it into the DG1022Z as an AWG file.
The DG1022Z hasn't been hacked (yet) but the only things you won't get are a) deeper AWG waveform memory and b) sine waves up to 30/60 MHz (the DG1032Z/DG1062Z ($500/$850) only give you the deeper memory and
sine waves of higher frequency, the spec of non-sine wave stuff is only up to 25 MHz for all 3 models as far as I can tell.
I considered buying one of the XX6600 AWGs but came to my senses and decided to order a DG1022Z that arrives today, I've wasted too much time f***ing around with beta-level products that never get supported properly to do it again.
