Well,
Following on from my musings last time about this FeelTech Signal Generator I purchased from Amazon, I've created a video to demonstrate some of the issues I have been seeing.
There are quite a few of the issues captured in the video, but other ADDITIONAL issues I have seen but couldn't reproduce during the video are:

Following on from my musings last time about this FeelTech Signal Generator I purchased from Amazon, I've created a video to demonstrate some of the issues I have been seeing.
There are quite a few of the issues captured in the video, but other ADDITIONAL issues I have seen but couldn't reproduce during the video are:
- DC offset on Channel 1 (video demonstrates this issue on Channel 2 only)
- Channel 1 and Channel 2 incorrectly out of phase
- Both Channel 1 and Channel 2 failing to start (reproduced by both channels set to 10MHz and 0.5V then soft power cycle)
The issues documented in the video include:
- Channel 2 fails to start on soft power cycle
- Channel 1 and 2 amplitude issues
- Issues around 0.5V amplitude
- DC offset on Channel 2 (even during soft power off)
The firmware in my version is 3.2 which I understand to be the latest at the time of writing.
My conclusion? It's a piece of junk.
I'd be interested to learn if anyone else can reproduce these issues as it might be that this is some firmware but also I suspect crappy Chinese relays may be part of the problem.
