Re: Uhf TV monitoring, Antenna testing

 

I saw the video you suggested. However, I have a question. In other videos I have seen they say that an attenuator is required on the high side. Is that correct, or can direct testing of tv signals be done without it?

Re: Uhf TV monitoring, Antenna testing

 

I made a comment on your above linked youtube video, but as a relative newbie to RF, I have some questions...

When using this for TV antenna aiming or just for inspection of the signals on a cable TV feed, does the fact that the cable lines are usually set up for 75 ohm make any difference here?? Is the tinySA set up for 50 ohms?? I am shopping around for a simple F-type to SMA adapter and was curious if there is anything special I need to consider there.? (I only have BNC-SMA adapters right now).

I also asked about the presence of the FM broadcast signals on your youtube video, but you didn't answer that question.? Is this common practice in your area?? I have not heard of this being the case in the US.

Look here:?
Its using cable for demonstration but the type and strength of signals should be comparable when using a good antenna
Towards the end it is shown how you can use a TV signal to calibrate the high input

Uhf TV monitoring, Antenna testing

 

New here. Can't find where to add my callsign. I'm in the process of replacing my tv antennas.I receive signals from different direction and want to use the TinySA when it arrives to point my antennas and determine if amplification is needed. Open to ideas. Thanks.

I had this problem and it turned out my USB cord that I was using was actually not made with a data line. And apparently it was just for charging. Change chords and fixed my problem.

FM deviation measurement (narrow and wide)

 

Can the TinySA be used to measure the FM deviation of a transmitter? E.g. the narrow of a 144 MHz TX or the wide of a FM broadcast one? Thanks.

Ah OK, I thought that the TinySA app installed the drivers too, my mistake.

The DFU drivers must be installed separately (and correctly) for this to work.

Yes, it can work but only if you have the DFU mode drivers installed. Most problems trying to upgrade the firmware (using DFU or whatever) are caused by lacking this driver, that is not the normal one for running the SA controlled by a PC.

If it is the Tiny SA app, it has a built in upload feature you can use, which makes it all very easy.

Use the button bar on the top row with the two black triangles

I can confirm the USB cable issue, too.

Yesterday, I went to update firmware using the same PC I originally updated FW with right after I got the tinySA.? I couldn't get it to recognize the tinySA and I spent 20 minutes trying to figure it out.? Finally tried a different cable, and everything worked as expected.

Both the USB to USB-C adaptor cables I got with my NanoVNA and TinySA were bad. I bought a few adaptor cables from a reputable seller and have had no problem with them.

i have TinySA version v-1.3-111-gob2fe54 May 15, 2021.
It operates beautifully and i would like to do the firmware update.? However, I do not see the unit recognized in the DFU program.? I followed the steps as showed in the wiki instructions.
What can I be doing wrong.?? BTW, It works beautifully with a Windows 10 SA program.

This is the tip on my active Capacitive / resistive stylus.? It is a hard tip.? When it is on it will work on my iPad screen and my tinySA.? If it is off it will only work on the tinySA, nanoVNA-F, and IC7300 as a resistive stylus.? I like using it because I only need the one stylus for all the gear I use it on.? I do agree the squishy ball type are not very usable.? The bulb is always to big.? Tried them and hated them.

I was referring to the style with the soft/squishy flexible rubber ball shape at the end - not the hard tipped variety (if those exist).

For those of you looking for sylii in the US, just search amazon for "plastic stylus resistive" (or ebay or any other shopping site).? There are many options out there.? I don't think you want a capacitive stylus, since the tinySA is a resistive touch screen.

A lot of the results I got on a quick amazon search looked like they were for the Nintendo 3DS. I saw a 50-pack (not necessarily for the 3DS) for around $10.



The stylus I use is one i found in a drawer here - it came with a resistive touchscreen I ordered off ebay I think.? Mine is roughly the same length as the collapsed antenna that comes with the tinySA, and I like that size since it fits in my custom 3D printed case.
