RFI (Radio Frequency Interference) Sleuthing with the TinySA (2021)
- wkat4242 3y agoThere's also a premium version of the tiny SA that has a bigger display and wider frequency range, resolution bandwidth etc. I've been thinking of buying that one.
- Citizen8396 3y agoWould you mind sharing a link?
- wkat4242 3y agoAs per above: https://tinysa.org/wiki/pmwiki.php?n=TinySA4.Comparison https://tinysa.org/wiki/pmwiki.php?n=TinySA4.Comparison The Ultra is more than 2x as expensive (but considering the prices of regular spectrum analysers, still quite cheap for its capabilities!)
- tinix 3y agoAre you thinking of nanovna? There's only one tinySA afaik ..
- tinix 3y agoAhh found it: https://tinysa.org/wiki/pmwiki.php?n=TinySA4.Comparison https://tinysa.org/wiki/pmwiki.php?n=TinySA4.Comparison
- wkat4242 3y agoYeah I meant the Ultra. When I wrote that from my phone I forgot the exact name. The nanoVNA is a completely different thing - as mentioned in the article also.
- transpute 3y agoAnother directional loop antenna for RFI location (2019), https://www.arrl.org/files/file/Antenna%20Book%20Supplemental%20Files/24th%20Edition/Handheld%20DF%20Antenna%20-%20NA6O.pdf https://www.arrl.org/files/file/Antenna%20Book%20Supplementa... Here is a simple antenna design that is effective from 3 to 22 MHz. Based on a resonant magnetic loop, it has high transducer gain (high sensitivity), and also very good directionality. You can build it cheaply from junk box parts.

- luckman212 3y agoCan this be used to visualize 802.11ac/ax signals?
- notslow 3y agoHighly unlikely. 802.11x lives in the 2.4GHz and 5.8GHz ranges which are outside of the stated range of the tinySA mentioned in the article. Occasionally radios will work outside of the stated range with a bit of hacking, but 950MHz to 2.4GHz is pretty far. Software-defined radios (SDRs) like the HackRF One or BladeRF cover the 2.4GHz and 5.8GHz frequency ranges, but at a higher cost. [edit: clarify the frequencies of the HackRF and BladeRF] [edit2: Apparently the tinySA Ultra can cover the higher frequencies in certain configurations]

- kqbx 3y agoFor this purpose, how does TinySA compare to scanning the spectrum with an RLT-SDR (or other low-end SDR)?
- transpute 3y agoBetter portability, https://news.ycombinator.com/item?id=39144472 https://news.ycombinator.com/item?id=39144472
