Many clone suppliers of this design. The DDS is probably a AD9851. Frequency counter modules are available for < $15 (cloned hobbyist design, perhaps incorporated here?) 2.4" TFT color LCD screens retail under $5 in singles, and there's plenty of driver code for Arduino and STM32. Don't know what DAC the ARB generator uses, but there's not much magic there. The magic is to be able to make a profit, at these prices. <https://www.aliexpress.com/item/JDS6600-Series-MAX-60MHz-DDS-Function-Signal-Source-Digital-Control-Dual-Channel-Arbitrary-Wave-Function-Generator/32866324994.html>

It's amazing that someone cound set up a serious electronics lab now (scope, generators, DVM, power supplies, soldering stuff, Spice and PCB software) for way under $1000, and get parts and proto PC boards dirt cheap.

The lower frequency versions are significantly cheaper. It appears to use an Altera Cyclone IV FPGA driving 14-bit DAC. 320x240 color TFT. This is NOT your hobbyist DDS chip. Certainly not as nice as a Keysight (or whatever they're calling themselves these days) or a Rigol, but very economical. --sp

So they say "‘True gold fears no fire" (a person of integrity can withstand a severe test) https://chinese.yabla.com/chinese-english-pinyin-dictionary.php?define=%E7%9C%9F%E9%87%91%E4%B8%8D%E6%80%95%E7%81%AB%E7%82%BC Looks like there might be competitive units (possibly copies) which use resistor networks direct from the FPGA outputs rather than the DAC. They also claim 60s short-circuit capability on the outputs (my Agilent Arb has a bunch of relatively expensive op-amps in parallel to get the output drive). I would say some caution is called for if one wants to buy one of these apparently identical units. --sp

This is NOT your hobbyist DDS chip.The prevalence of cloning in this kind of device is usually because someone published the designs. It's often an advanced hobbyist. I have a couple of gadgets like this; if you search hard enough you can find the original blog postings showing where the design was developed. There are plenty of hobbyists advanced enough to have developed this design. I haven't searched, but mere hardware copying wouldn't result in the plethora of clones; the original software has to be published somewhere. Otherwise the cloners would have to write it again (differently) to accommodate any design changes, and that's too much like hard work; they'd need to understand how what they were cloning works.
