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

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

Re: Input RF switch fault found on TinySA ultra
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.
Low-melting point solders like Chip-Quik also have their place in your

The tinySA automatic scanning is stopped, hence the "paused"
Instead, the tinySA-App send scanraw commands, possibly with much higher resolution, and you see the green line of the progress of the

Re: Testing coax cable
Yes, the TinySA is a spectrum analyzer. The NanoVNA is a network analyzer.
The NanoVNA can be used to measure impedances of coax, the rate of loss of
coax over a frequency range, SWR. It has a TDR
