Re: Help ! Calling Ghostbusters.
That's what I was hoping a tool like the tinySA could help me determine.
For Wi-fi frequencies, an RF scan from my 2 wired Unifi U6-LR APs shows negligible interference on any channel, on either the

Re: Help ! Calling Ghostbusters.
Thanks. My guess is that it's from my property, based on low density of building/population around here. 2 houses down is a farm. I could be wrong, of course. For radio reception, I already have an

Don,
Thanks for your reply. Response inline.
Actually, due to macular degeneration, I really want to be able to set at least the color temperature dynamically, and dim as needed. Some tasks and

Re: Testing coax cable
I don't see why.
If I measure power level x, with a SA
And then if I insert a 10 dB attenuator.... I usually see a 10 dB loss... maybe a little more due to connector losses, etc.

Re: Testing coax cable
You can see the loss at a particular frequency... but AFAIK, you can't do a sweep from 470 MHz to 600 MHz, and plot a graph.
Because, AFAIK... Tiny SA does not have a tracking gen. (You need one to

Re: Would like to report a new fake chinese hardware for TinySA
Erik,
When my refund comes I will certainly be buying from one of the authorised stores that I now know about.
Funny how a fake clone makes me discover a new project that I didn't know about.? Life

Re: Input RF switch fault found on TinySA ultra
I prefer to use a more subtle approach, I turn my hot air station to near minimum airflow and apply background heat so that the PCBA is at perhaps 80C, too hot to touch.? I don't bother with Kapton

Re: Input RF switch fault found on TinySA ultra
Well, since over 10 years I'm very happy with my headband magnifier. Those days bought from RS. Article Nr. 606-989 looks approximately the same. It fits also over a pair of glasses. But (yet) I don't

Rainer,
Thank you for your reply, and sorry I can't get to everyone's reply timely.
Thanks. I'm unfortunately well aware of the MAC address limits. The Ubiquiti APs I use advertise being able to

Re: Help ! Calling Ghostbusters.
The reason for the Wifi bulbs is not on/off control. If that were the case, I would indeed only be using smart relay switches. The Wiz bulbs allow dimming, setting brightness, color temperature,

Re: measuring spectrum of a single pulse not feasible with TinySA?
You can also do the FFT calculation off line in python if you can capture a data plot from the scope. Most modern scopes let you transfer them to a PC to do this even if they can't do the FFT

Yes, you definitely need a microscope. If you're a hobbyist and you solder
often you'll not regret buying a good microscope. Key thing is it has to be
a normal optical microscope with at least

Re: Input RF switch fault found on TinySA ultra
Applying background heat to the PCB helps in using lower temperatures and reduces thermal stresses on the board and components.
