The tinySA ultra is a handheld 100 kHz - 6 GHz spectrum analyser which is designed, developed and now sold from Eindhoven, The Netherlands. The tinySA ultra is a follow-up to the tinySA. The differences between these two spectrum analysers are described in the model overview below. Moreover, this device comes with a 4.0-inch resistive touch color display which shows the full frequency range in 450 scan points, and has a rechargeable battery included for up to two hours of portable use. Furthermore, the analyser features two different modes: normal mode and ultra mode. Additionally, the tinySA ultra has many built-in configuration options such as a switchable bandpass filter and a low-input step attenuator. It's important to keep in mind that the maximum input level of the tinySA is +6 dBm. If you're unsure about the input level of your signal, it's recommended to use an attenuator to be on the safe side.

When the tinySA ultra is not used as a spectrum analyser, it can be also used as a signal generator to output sine or square waves.

The analyser can be fully controlled by a PC through a USB cable. It also features an automatic self-test and self-calibration through the built-in signal generator.

The tinySA and tinySA ultra developer has set up a very extensive wiki page with all necessary information, manuals, operating limits, and explanations. This wiki can be found here.
We sell the original version, be aware of many clones in the market!

The tinySA ultra includes:

  • TinySA ultra spectrum analyser
  • Two SMA connection cables
  • Barrel connector
  • Antenna with SMA connector
  • USB-C charging cable
  • 32 GB micro SD card


The TinySA ultra is an open-source product with support from the community. Most questions are answered in the Wiki, for further problems you can go here. By default, the ultra mode is disabled, but the ultra mode can be enabled by following the instructions described on the Wiki. Therefore we do not provide technical support on the TinySA ultra. Warranty on the hardware is of course provided by Eleshop.

Pros and cons

  • Excellent price/quality ratio
  • Ultra mode has a frequency range up to 6 GHz
  • Built-in audio jack

Ik vind het grote voordeel van dit apparaat dat het portable is, de gevoeligheid goed en dat het frequentiebereik ruim over de 5GHz gaat.

Het is vrij eenvoudig om zelf een H-field probe te maken met wat dunne coax en dan kun je makkelijk in een apparaat lokaal signalen oppikken.

Ik adviseeer om gelijk 1 of meerdere verzwakkers (10 of 20db) erbij aan te schaffen, omdat signalen (vooral op buitenantennes) nogal sterk kunnen zijn.

Zeker als je, zoals ik, vlak naast een parkeergarage met veel antennes, woont.

Ook handig voor erbij: verloop bnc naar sma of N naar sma,

Im an electronics engineer and mostly work with low speed signals, low noise and no radio. In other words, spectrum analyzers are outside of my regular tools.

This instrument is perfect for my use since its low cost and high performance for the price, it allows me to analyze the different frequency components of my circuits, something that's previously been a hassle. The built in LNA is a great feature since it allows me to directly connect field probes making the setup very continent.

Would recommend this product for people who need a spectrum analyzer occasionally and still want good performance while not spending many thousands for a benchtop SA.

The Tinysa ultra is an useful instruments, the specifications checked in laboratory are very good for sensitivity, frequency range, accuracy.
A cost/performance reference in the market.
Eleshop is a reliable , fast, professional supplier with its know how for test instruments.
There are well done Tinysa web sites, we technicians can get informations and partecipate to the improvements.
