This result has the consequence of sending any electronic design to the ChiNAZI regime, you expose yourself to the theft of intellectual material versus its low manufacturing costs. it is better to send your designs to factories in Taiwan than if you respect intellectual property and have an excellent level of electronic manufacturing.
The 146.527 spur amplitude just about disappears after you reconnected the cable. As you were tightening it, the amplitude of the spur went back and forth between ≈-35 and ≈-50 dB, ending up settling at ≈-50 dB, starting about the 4:17 mark. Dodgy cable, connection?
Seems like it, SMA connectors aren't the best they're pretty fragile, and don't always make the best connection, and the cables that usually get used with those connectors usually isn't of the best quality either. I really wish they would have used BNC or something a bit more robust that could accept a better coax.
You've demonstrated that you can use the VNA as a signal generator! That's great! I mean, it has to do that to measure SWR but makes me wonder if you could do receiver alignment, etc.
Just love your videos Sir! I am not technically mimded on this subject amd don't follow everyting but your style, voice and presentation makes it so interesting, keep them comming please. Subscribed.
be aware that the tinysa high side does not have the same performance as the low side. much of the circuitry is bypass and the noise and spurs are quite large.
The nanoVNA can not output above 300MHz, it uses harmonic modes above 300MHz. If you set 800MHz you get 266MHz
and if you set 440 MHz you get 146MHz

@@guillermoiturriaga7863 OR extend our high-end component / processor factories in the US to accommodate low-end / high market presence components.
You did everything I did with mine, including forgetting that the LOW input couldn't see 440 MHz. :)

yes, the tinysa has a generator mode.
Can any of these sweep above 600MHz ? I need one to see if any LTE signals are interfering with OTA channels in the 5-608Mhz range.
The TinySA would probably be useful. It is best up to 350MHz but has a second mode to 960MHz

Your SMA cable may have an issue in the second half of the video
Please include a SMA to male F connector cable or adapter in future releases so we don't have to order an extra cable to test TV antennas.
Low is 0-300M and High is 240-960M You need to change the input to high of the tinysa
What is an approximate RF input signal that Tiny SA can handle without damaging it?
I limit it to 0dBm (1 milliwatt)

How is your lockdown going
You need to change the input on the sa to read above 350 mhz

it would be interesting to see Nano on o-scope also,...
Hi. Can you review and compere nanoVNA-F
Sure. Buy me one :)
@@IMSAIGuy wher you live?
@@k19radio13 Santa Clara
@@IMSAIGuy pleas write me i have proposal if you agree. k19radio@gmail.com
buy one for me to !
Don't you have to connect to at 440M
I feel that both models are of the same design!
the battery, display, case, same, some of the firmware same. rest is way different
Where can one buy this item?

We have a little too much time on our hands do we, IMSAIGUY?

На LOW разъеме 800мГц искать!?? Забавно)))))
Ha!
