So you're probably thinking why does this guy have a VNA if he has no idea how to use it.   Well, read on.

Here's what I would like:

  • Lessons in English via remote Zoom/Skype on how to set up SA/VNA for doing various measurements.
    I'm mainly interested in LoRa devices as that is what my company builds
    I have a Siglent SVA1015x with EMI option

By the end of the lesson(s) I'd like to be able to zip around on the VNA and measure things like dipole antennas, EMI pre compliance (I have a TEM cell too), making sure my precertified Murata ABZ LoRa module is behaving.  What I really want to know is will my device pass FCC.  I have limit lines and EMI option.  Scan search measure etc.

We have modified the Pi network for future HazLoc certs so we need to submit for FCC/IC/CE certs.  I had an RF engineer run tests and he tuned it and tested the end result.  Said it was matched well after tuning.

So why do I own equipment and not know how to use it?  Because I started an IoT company around a niche area.  I'm not an EE, I'm a sales guy.  But I need to learn this as I am chief, cook and bottle washer.  I'm a fast learner and very flexible around your schedule.  I know I can watch youtube videos but I find coaching helps me get answers faster.  I'm not a complete beginner but pretty close.   

Let me know if this interests you and we can discuss further.  You likely would need to have this same tool or be familiar enough with Agilent (as they seem very similar to my Keysight N9000B I borrowed), I can also screen share.

Thx

Check out the EMI App notes on the SSA3kX Plus webpage.
https://siglentna.com/operating-tips/ssa3000x-plus/

As all Siglent's SSA's except the older SSA3kX have a new EMI mode you need read up on how to work it in the latest version of the manual.

Suggest you move this topic to the Beginners or TE board so others with later model SSA's and SVA's can chime in with tips and screenshots of using the new EMI mode.

Thanks i will certainly do all i can to learn but was hoping to fast track some setups this week.  Figured i could pay someone else to help me learn faster.

If this is not correct forum please feel free to move it.

BTW, for EMI work the frequency range is typically quite small and just a few 100 MHz max. In the new EMI mode there are preset ranges that correspond to the testing standards.
Typically unpowered RF probes will require the SA Preamp engaged so to supply the SA with enough signal strength for measurements.
More later when I can find some screenshots in my records.
