OWONAG1022 Series AG DDS Arbitrary Waveform Generator, 2 Channels, 25MHz, 125MSa/S Sample Rate

I gave it two stars because it does actually produce some waveforms, and it's pretty cheap.You can only define waveforms from the front panel, and editing arbitrary waveforms is excruciating. There is no way to transfer data from a PC or to edit your saved waveforms on a PC. The "Software" that ships with the product is just a duplicate of the front panel shown on your screen, and it gives no functionality except what you can do from the front panel.Today I have downgraded my review from 2 stars to 1. The front panel encoder no longer works. It probably just needs some contact cleaner, but they have made the unit hard to disassemble, so it's not even worth fixing.
