Om het energieverbruik en de grootte te minimaliseren, gebruikt de NanoVNA een enkele mixer, die is uitgerust met meerdere interne RF-schakelaars voor de afmetingen S11 en S21. De IFFT-berekening voor TDR en DTF-metingen.

Het meetbereik bedraagt tot 6,3 GHz om in staat te zijn om te voldoen aan de gebruikelijke toepassingen van amateur- en IoT-amateurtoepassingen en 5 GHz pop-up tests. Bovendien maakt de machine de toepassing van de nieuwste 5,8 GHz wifi en 5,8 GHz beeldoverdracht mogelijk.

Opmerking: Deze VNA analysator voegt een stroombeperkte weerstand toe. Het is voornamelijk ter bescherming van de batterij en de USB-interface, zodat je de VNA vóór het opladen moet uitschakelen. In uitgeschakelde toestand kan het apparaat normaal worden opgeladen.

Durable, even for a Great Dane!
Color: Ultra, Size: XXL
I've bought many tennis ball sized ChuckIt balls in the past (for medium sized dogs we've owned), so when we knew we were going to be babysitting our daughter's Great Dane, I bought a bigger one for her. The 4" is perfect for her! She plays catch with it, but also likes to gnaw on it. It holds up great!

Another great product from Chuckit!
Color: Ultra, Size: XL
Exactly the high quality that I've come to expect from Chuckit! The plastic/rubber used in their products is extremely tough yet gives enough that it's hard to actually pierce the it and tear apart. We have had Chuckit! Sticks and Balls with launcher for years and love them all. This particular ball is pretty big so my 45 pound pit mix struggles to pick it up but that's part of the fun for him. My 85 pound pit mix can pick it up no problem. The only "complaint" is that the two of them have been having so much fun with their new ball, they have already knocked something over and broke it. 😁

Perfect for my mid size pit bull
Color: Ultra, Size: XL
Updating my review, the ball only lasted 5 days. I left the 5 stars because we had enough fun those 5 days to be worth the small price. She has dog has a lot of jaw strength, so I’m not surprised We have a mid size foster pit bull. This ball is her favorite toy. It’s durable and the perfect size for her to play ball safely.

Good quality
Color: Ultra, Size: Large, Color: Ultra, Size: Large
Great quality. I purchased for my daughter’s dog who destroys all toys. This toy holds up. I didn’t realize it was a large and the chickit stick she had was a medium. The large ball ended up working out good for playing inside the house. The dog likes it a lot.
