Hi Everybody:

I am new to the group. I am an equipment maintenance tech in the semiconductor industry, and here is my issue:

Every once in a while I would like to hook up to Analog and Digital data logging test points, in different places all over a piece of equipment, to isolate an intermittent fault.

I rarely have access to any ladder logic diagrams, and never have access to software code flow charts, so, as I am sure some of you can sympathize, I make do the best I can.  Usually that means isolating candidate test points through available schematics.

My dream would be to have wireless transmitters that I could hook across ground and the signal testpoint I want to monitor, verify transmission, and walk away. But I am concerned about RFI issues generated by a wireless solution, and I have no idea what is currently available for this application

Additionally, the data capture software, would ideally be, inexpensive.

Your thoughts?

Thanks, I appreciate your time to respond.

I don't know how far apart your test points are, but maybe something like this can be helpful. I'm currently in the process of trying to get a Raspberry Pi running with some ADC's connected to it to do some logging. I have almost no programming experience but I'm slowly getting some results. I will be using wired ethernet but you can plug in a wifi dongle if you want wireless.

@petieken.  That sounds interesting, I hope you can share your project with us as it progresses.

Here is a similar project I saw that you might request to join: hackaday.io/project/7601-open-source-data-logger-rpi
