The OWON DGE2070 Channel 1 and 2 phase alignment is
- The two outputs operate at a random phase offsets from one another by default.
- There is an option buried under "Utility->Ch1/2->Align phase", which will align Ch1/Ch2.
- This alignment is lost if you even so much as look at the device again, or:
- turn off either channel
- press the "Ch1/Ch2" button to view the channel settings again.
- Make another phase adjustment or any other channel parameter adjustment.
So basically, if you need a fixed phase between Ch1 and Ch2, your best option is to "Align phase" after every single action you take and keep both signals on the scope so you can verify their alignment. before using the outputs.
Effectively, this is hardly better than having two single channel ARBs, and is a total deal-breaker for me. I'm bitter because I really wanted to like the OWON.
The Uni-T UTG962 just aligns the channel phases, as... any normal implementation should.
Windows software notes for both OWON and Uni-T:
- Would not rely on either.
- Got both installed (windows 11 machine)
- Uni-T software package is middle-school production quality. On second thought, I'm sorry for insulting middle-schoolers, you're right, they can do better. The installation package installs umpteen different programs and drivers, each one of which cause windows to panic, including a "Device Manager", which manages to be the most confusing/misleading name chosen for something to be installed on Windows.
- The OWON software installer and application seems far better put together.
- The actual waveform editor UI of both the Uni-T and OWON is equivalent to etch-a-sketch with a mouse.
- I cannot write to the Uni-T device at all. Uni-T "Device Manager" sees the sig generator, but when I "Down file", "Number of devices found" is always 0. Obviously others have had better luck, so I am open to suggestions.
- I was able to write and replay a waveform from the OWON (keep reading):
- I cannot for the life of me figure out which of the 16 slots the software will write to (suggestions welcome).
- The first time, it wrote to USER5, then to USER0 (judging by these slots showing 16kB size)
- USER0 after a while stopped loading (always throws "File read fail" error), and I cannot choose another slot... so no more custom waveforms for me?
