Review: Well deserved 5 stars - 5-Star Review – AURSINC TinySA Ultra+ ZS406 Spectrum Analyzer Alright, let me just say—this little device punches way above its weight class. The TinySA Ultra+ ZS406 has completely surprised me in the best way possible. I gave it 5 stars, and here’s why: Ease of Use Right out of the box, this thing is ridiculously intuitive. The menu layout is straightforward, no guesswork, no hunting through layers of submenus. I was up and scanning signals in minutes—without needing to crack open a manual or hit YouTube. It just works. If you've got even a basic grasp of signal analysis, this will feel like second nature. If you're a beginner? It won't take long to get comfortable. Readability The screen is sharp, bright, and legible even in less-than-ideal lighting. The data presentation is clean—no clutter, no nonsense. Colors pop just enough to give clarity without distracting from what you're actually trying to see. Whether you're doing quick scans or locking onto a signal for detailed inspection, you're not going to be squinting or second-guessing. Consistent, Clear Readings This is where it earns serious respect. The readings are not only accurate, but repeatably accurate. No weird drift, no jittery signal noise that shouldn’t be there. Whether I'm monitoring RF noise in my workspace, checking transmitters, or just scanning for fun, the TinySA Ultra+ gives me consistent, reliable results every time. It’s fast, responsive, and most importantly—trustworthy. Final Word If you're on the fence about this unit—don’t be. Whether you're a hobbyist, a radio nerd, or someone who just needs to get clean spectrum data without a thousand-dollar rig, this is it. Compact, powerful, and polished. Solid 5/5. Absolutely worth it.
Review: Quality ultra compact spectrum analyzer - What an amazing compact device! Very well made and portable spectrum analyzer. Noise level measurement and frequency / bandwidth adjustment adequate for most uses. Battery capacity is good. Construction grade is very good. Has internal LNA or can alternately be paired with external LNA for various bands. Use with PC applications which can both control and record analysis.

- [WIDELY FREQUENCY RANGE] The Tiny sa ULTRA+ has an ultra measuring frequency range of 100kHz to 5.4GHz, spectrum analyzer for 100kHz-900MHz and Ultra mode up to 6GHz. Switchable resolution bandpass filters from 200Hz to 850kHz, you could fast and accurate execute measurement tests. Color display showing max 450 points providing gapless covering up to the full frequency range
- [2 IN 1 DEVICE] When not used as Spectrum Analyzer it can be used as Signal Generator, MF/HF/VHF sinus output between 100kHZ-900MHz, UHF square wave output between 800mHz-4.4GHz, Mixing signal output is between 4.4GHz-5.4GHz. Built-in calibration signal generator that is used for automatic self test and low input calibration
- [200Hz-850kHz RBW] RBW frequency from 200hz to 850khz which can be set to match the measurement requirements, meet SBB two-tone test requirements and fast scanning. The RBW is as low as 200Hz, which can effectively distinguish adjacent signals and meet the requirements of SSB dual-satellite inter-modulation test. Input Step attenuator from 0dB to 31dB (can not be used not in combination with LNA)
- [EXCELLENCE PHASE NOISE] Phase noise at 30MHz of -108dB/Hz at 100kHz offset and -115dB/Hz at 1MHz offset, DANL -166dBm/Hz. In the level menu, there is the LNA, which will provide 20db of extra gain if you have very low level signal (the LNA in tinySA ULTRA is only effective below 3.5GHz) The default maximum frequency is 800mhz, so you no longer have to switch between low and high range, and can monitor the complete range in one sweep
