I have used it for testing HF, UHF and VHF radios. The only other thing I needed was a 40 db attenuator. Review: Great performance for the price - We used this SA to diagnose and correct interference from TV stations that was interfering with a wireless mic system. By seeing where the interference was, we were able to move our wireless channels around the problem areas. It works well in the handheld mode (easy to control the touch screen with the included stylus) and even better when connected through the PC app. The controls (frequency range, RBW, VBW) are straightforward and produce scans that compare with much more expensive SA's. The only problem we ran into was with the PC app: After changing a setting such as frequency or RBW/VBW we sometimes needed to restart the scan or power-cycle the SA to reconnect the USB port. Otherwise, though it works great and is a great value for the cost. ## Features - Upgraded ZS406 TinySA Ultra+:This New Version V0.4.6.1 Spectrum Analyzer is developed by Hugen, with 4.0 inch 480 x 320 large touchscreen display, 100kHz to 5.4GHz widely measure range, with the new ESD protection function, the product has a higher anti-static level and a longer service life, and built-in 32Gb micro SD card, can directly record data to the card ,which is convenient for your data sharing and storage - Widely Frequency Range: Compared to the tinysa (100kHz to 960MHz), the upgraded tinysa ULTRA+ has 100kHz to 5.4GHz ultra-wide measuring frequency range, spectrum analyzer for 0.1-800MHz, with Ultra mode up to 0.1MHz-6GHz.Switchable resolution band pass filters for both ranges between 200Hz to 850kHz. Color display showing 450 scan points covering up to the full low or high frequency range. Faster and more accurate measurement performance, you can easily cope with measurement testes in various fields - 2 in 1 Multifunctional Frequency Analyzer & Signal Generator:When not used as Spectrum Analyzer it can be used as Signal Generator,with sine wave output between 0.1-800MHz or square wave or dual tone output up to 4.4GHz.Built-in calibration signal generator that is used for automatic self test and low input calibration - PC Control: Connected to a PC via USB it becomes a PC controlled Spectrum Analyzer or Signal Generator.Tinysa-APP transfers data directly to the computer.The USB interface implements CDC protocol and there is a large set of commands that can be invoked over the serial interface. These command can be used to perform measurements or update internal settings. The driver for Windows will install automatically after connecting to a Windows PC. The driver for Linux is built into the kernel - Ultra-long Battery Life: The upgraded tinysa analyzer built-in 5000mAh battery,with type-C charging cable and LED charging indicator,it can be fully charged within 3 hours,no need to charge frequently - Excellent Phase Noise Performance: With advanced spectrum analyzer, especially tinysa ultra, outstanding phase noise performance is shown. At 30MHz, phase noise is -108dB/Hz at 100kHz offset and -115dB/Hz at 1MHz offset. DANL is -166dBm/Hz. There's an LNA in the level menu, which offers 20dB extra gain for low - level signals (LNA in tinysa ultra works only below 3.5GHz). The default max frequency is 800MHz. No need to switch frequency ranges, and you can monitor the whole range in one sweep - Package Contents: 1x ZS406 Tinysa ULTRA+ Spectrum Analyzer (built-in 5000mAh battery), 1x 32GB Micro SD card (plugged in the host) 2x 30cm ALSR100 SMA cables,1 x USB Type-C data cable, 1x SMA-SMA barrel connector,1x TLanyard and touch plectrum; 1x Antenna with SMA connector, 1x stylus touch pen ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BBGK9QJB | | Best Sellers Rank | #32,458 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #6 in Spectrum Analyzers | | Brand | Seesii | | Brand Name | Seesii | | Color | Black | | Compatible Devices | PC | | Customer Reviews | 4.5 out of 5 stars 254 Reviews | | Included Components | Tinysa ULTRA+,SMA cables,SMA connector,Antenna,32GB card,Touchscreen pen | | Item Dimensions | 6.69 x 4.72 x 2.56 inches | | Item Weight | 265 g | | Item dimensions L x W x H | 6.69 x 4.72 x 2.56 inches | | Manufacturer | Seesii | | Model | SEESII- TinySA ULTRA+ | | Part Number | TinySA ULTRA | | Power Source | Battery Powered | | Style | TinySA ULTRA+ | | Style Name | TinySA ULTRA+ | | Unit Count | 1 Count | | Warranty Description | 3 Year Manufacturer | ## Product Details - **Brand:** Seesii - **Color:** Black - **Item Weight:** 265 Grams - **Power Source:** Battery Powered - **Style:** TinySA ULTRA+ ## Images ![SeeSii TinySA Ultra+ ZS406 Spectrum Analyzer, 4.0 Inch 100kHz to 5.4GHz Handheld Tiny Frequency Analyzer with 32Gb Card, 2-in-1 Signal Generator MF/HF/VHF UHF Input,V0.4.6.1,2025 Upgraded - Image 1](https://m.media-amazon.com/images/I/81Vy91IOx9L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: The data is compatible with wireless workbench (shure) and wireless system manager (sennheiser) ?** A: I seriously doubt it.

I have used it for testing HF, UHF and VHF radios. The only other thing I needed was a 40 db attenuator. ### ⭐⭐⭐⭐⭐ Great performance for the price *by M***C on November 17, 2024* We used this SA to diagnose and correct interference from TV stations that was interfering with a wireless mic system. By seeing where the interference was, we were able to move our wireless channels around the problem areas. It works well in the handheld mode (easy to control the touch screen with the included stylus) and even better when connected through the PC app. The controls (frequency range, RBW, VBW) are straightforward and produce scans that compare with much more expensive SA's.

Otherwise, though it works great and is a great value for the cost. ### ⭐⭐⭐⭐⭐ Great product for the price. *by D***S on July 2, 2024* I never thought that I could by a spectrum analyzer for less than $200. This product is amazing for what it will do. As a Ham radio operator, this item can be used for many things. Being able to test the sensitivity of a receiver or antenna system is great. Scanning the spectrum to find new frequencies in use for either Ham or scanner enthusiasts is easy. It can be used to determine field strength measurements. All in a hand sized package! This unit will not replace a bench SA that costs thousands of dollars, but it gives almost anyone the ability to use basic SA functions with their radio gear. ## Frequently Bought Together - SeeSii TinySA Ultra+ ZS406 Spectrum Analyzer, 4.0 Inch 100kHz to 5.4GHz Handheld Tiny Frequency Analyzer with 32Gb Card, 2-in-1 Signal Generator MF/HF/VHF UHF Input,V0.4.6.1,2025 Upgraded - BECEN 10W SMA Attenuator,40db,DC to 3GHz,50 Ohm - DHT Electronics Handheld Antenna Cable SMA Male to UHF SO-239 Female Connectors 6'' Pack of 2 for Amplifier --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/501038005-seesii-tinysa-ultra-zs406-spectrum-analyzer-4-0-inch-100khz](https://www.desertcart.tn/products/501038005-seesii-tinysa-ultra-zs406-spectrum-analyzer-4-0-inch-100khz) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-07*
