Product Details
✓Upgraded TinySA Ultra+ ZS406: Built on the latest HW V0.4.6, the AURSINC TinySA Ultra+ ZS406 features a 4.0 inch 480*320 touchscreen display for intuitive operation. It comes with a pre-installed 32GB micro SD card for convenient on-site data storage and sharing, and a built-in 5000mAh rechargeable battery that delivers at least 3 hours of continuous operation on a full charge
✓Wide Frequency Range & Adjustable RBW: Covers a measurement range of 100kHz to 5.4GHz, with Ultra mode extending up to 6GHz. Switchable resolution bandwidth from 200Hz to 850kHz enables fast and accurate measurements; the 200Hz minimum RBW clearly separates adjacent signals and supports SSB two-tone intermodulation testing. It includes a 0–31dB input step attenuator and displays up to 450 points for gapless full-band coverage
✓2-in-1 Analyzer & Signal Generator: Doubles as a signal generator when not used for spectrum analysis. It outputs MF/HF/VHF sine waves from 100kHz to 900MHz, UHF square waves from 800MHz to 4.4GHz, and mixed signals from 4.4GHz to 5.4GHz. A built-in calibration signal generator supports automatic self-test and low-input calibration for sustained measurement accuracy
✓Excellent Phase Noise performance: -108dB/Hz at 100kHz offset and -115dB/Hz at 1MHz offset (at 30MHz), with a DANL as low as -166dBm/Hz. An integrated LNA provides 20dB of extra gain for low-level signals (effective only below 3.5GHz). The default 800MHz maximum frequency eliminates the need to switch between low and high ranges, enabling full-band monitoring in a single sweep
✓PC Control: Connects to a PC via USB for data transfer and device control through the TinySA-APP, using Serial over USB (CDC) protocol with a full command set for measurements and internal settings. Drivers install automatically on Windows and are natively built into the Linux kernel
✓[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
