AURSINCAURSINC 2025 Upgraded TinySA Ultra+ ZS406 Spectrum Analyzer, 4.0 Inch 100kHz-5.4GHz HW V0.4.6 Handheld Frequency Analyzer with 32Gb Card, 2-in-1 Signal Generator 100kHz to 900MHz MF/HF/VHF UHF Input
Main highlights- [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
- [WHAT YOU GET] 1x Tinysa ULTRA Spectrum Analyzer (built-in 5000mah rechargeable 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 pen
- [UPGRADED SPECTRUM ANALYZER] AURSINC Tinysa Ultra+ ZS406 installed with NEW HW V0.4.6, with 4.0 inch 480*320 touchscreen display, 100kHz to 5.4GHz widely measure range. Built-in 32GB micro SD card, solving the on-site data storage issue, convenient for data sharing and storage. Built-in 5000mAh battery, a fully-charged battery allows for at least 3 hours of operation, without frequent recharging interruptions
- [PC CONTROL] This tinysa ultra can connect to a PC via USB, Tinysa-APP directly transfers data to the computer. The USB interface implements the Serial over USB (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
- [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
- [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)
- [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
