tinySA Ultra+ ZS-407 spectrum analyser reviews

Dear Eleshop Team,

Thank you for asking for a review of the shop.
Overall, I am completely satisfied with the shop and would love to leave a top-notch review. However, in today's era of international markets, I would appreciate having a choice regarding the language used. Given the capabilities of modern AI, it would be great to be able to select the language for all communications.

While I was extremely satisfied with the service, I was very unhappy with the main device itself—partly due to the language issue and the way it operated. I want to be able to use a measuring instrument simply and reliably. Unfortunately, that wasn't possible, which is why I returned the entire order.

Best regards from Germany,

C. Hass

The tinySA Ultra+ is a wonderful little instrument. I'm using it as a portable field probing tool for sanity checking sources of EMI on some prototype circuit designs. Very easy to use and the UI is consistent with the NanoVNA.

We tested the device with Agilent instruments, and we were pleasantly surprised by its truly excellent performance.
Obviously it is much slower in measurements compared to instruments with a much higher cost.
The only problem we found is in using it as a generator in FM Modulation. Ingatti the modulation has a huge distortion (45%) at 1 KHz (25%) at 300Hz and is reduced to 3% at 100Hz.
Probably the DDS is not fast enough to follow the sinusoid at a frequency of 1KHz.
For the rest the quality/price ratio is surprising!
