Siglent SDS1104X-E and SDS1204X-E: Bode plot with a non-Siglent AWG

--- Quote from: MrTick on April 23, 2019, 11:26:55 am ---I've just recently got my hands on SDS1104X-E and I was looking for the solution to connect it to FY6800 AWG.
Thanks 4x1md for reverse engineering the Siglent communication protocol and your very nice solution.
But as I think using pc/raspberry to just translate the messages is an overkill, I've implemented similar code for ESP8266.
FY6800 has a nice uart connector on the back, the logic levels are 3,3V, the VCC is 5V however, so you need to find some way to drop it to 3.3V.
(I've realized that just when writing this post, fortunately my ESP-01 survived all tests fed directly from 5v. Currently I just soldered yellow LED in series, it seems to be dropping the voltage to ~3.2V)
I've used the simplest ESP-01 module.
Currently only FY6800 is supported, FY6600 and clones should work also.

Welcome and thank you very much for sharing this project.
It can be a good idea to develop a small PCB with a simple circuitry for voltage and logic level conversion. It can even be made like a plug which fits the rear connector of the AWG.

Would it be possible to create following setup:
- ESP8266 module
- DDS 0-60MHz 2Vpp out, wired to the ESP module
and use it with 1104X-E as the AWG?

I think yes. 2Vpp out must be defined in Bode settings of the oscilloscope.

The PCB I'm speaking about can be something like this one but with a female header connector which can be plugged directly into FY6600/JDS6600.

I just ordered some ESP-01 and goodies to see if I can get my FY6800 and SDS1104X-E play nice.
