tinySA Ultra Reviews: A 0.1 MHz – 6 GHz Spectrum Analyzer for $120

A few weeks ago the tinySA Ultra was released. This is a spectrum analyzer capable of operating between 0.1 - 800 MHz, or 0.1 MHz - 6 GHz with the 'Ultra' mode enabled. A spectrum analyzer is a tool that allows users to visualize signals on the radio spectrum.

Previously the standard tinySA was released back in 2020. The Ultra version brings enhancements to the frequency range, signal generator range, bandpass filter range as well as an optional 20dB LNA, and a larger 4 inch color display. 

The TinySA Ultra costs US$119 + shipping direct from the Aliexpress store in China, or $129.95 from R&L in the USA (currently out of stock). The full list of resellers can be found at https://tinysa.org/wiki/pmwiki.php?n=Main.Buying.

We wanted to thank RTL-SDR.com reader Ben for providing us with links to a bunch of reviews of the tinySA Ultra which we are posting below.

    Imsay Guy? He is more often wrong than right. He has only a mediocre grip on technology and many of his conclusions are wrong because he is missing the fundamentals of what he is talking about.

      Let us know when you start a YouTube channel about fixing old analog devices & playing with new technology. We’ll be sure to give you a fair shake upon review, I guarantee.

    Erik, great job. I just got my Ultra from R&L last night. In my opinion, this is what the tinySA should have been all along. The display size is now perfect for a “tiny” device. No more messing with high and low jacks. USB-C so it matches my phone and tablet. I only played with it for a few minutes but it feels exactly like the original, only enlarged. It feels like it could use a processor upgrade to increase the sweep speed at narrow bandwidth, but that’s for the next version.
    I hope that you release a tinySA MEGA that is a 7-10″ with a kickstand for the workbench. An HDMI out would be incredible too. USB mouse/keyboard functionality. (I know that you can control/display them with a PC but for a portable setup.)

    Unless the makers revert back to using USB A or use WiFi or Bluetooth to communicate with these devices, I won’t be buying one.
    I am sick of these crappy miniature USB connectors that fail after about 100 insertions.
    No thanks.

      Ultra has USB-C. Non-directional and worlds better than USB micro or mini. Yeah, It’s not USB-A but that requires a lot of board space. I can’t remember the last portable device that I had that had USB-A.

      • G1RNB

        I agree Ben, a little more board space but so much better…one wrong twist and USB-C is cactus.

        USB A is fitted to sveral of my portable devices such as the Funcube dongle Pro+, RTL-SDRv3, TAPR VNA, BladeRF2.0, ICOM 7200, so it’s perfectly doable.

        The very next article on hardware is the SDRplay RSP1A and…….It is fitted with the rugged USB-B connector.
        So much for being left behind…
        You’ve got no idea what you are talking about, haha.

    One thing to watch out for, that the ISMAI Guy shows is that Ultra Mode leaks signal OUT the input. At a pretty high level. I really recommend watching the video.
    That’s why Ultra mode isn’t enabled by default. You have to go to the website to enable it and read the disclaimer.
    It really needs a unity gain (buffer amplifier) on the input so that it doesn’t damage the device being measured.

    I hope that they make a TinySA MEGA that has a HDMI out. Or could use an Android tablet as a display. That’d be SUPER cool.

    As for R&L, I had a really good experience with them. I ordered two Tiny SAs from them in the past.

    R&L? I still have a bad taste in my mouth from dealing with them. Seems they moved their store location and never updated their website, so I wasted a two hour round trip to their store. This was pre-smartphone, so I had no way to find their new location while I was away from home. I think I’d rather deal with Aliexpress.
