[UPGRADED SPECTRUM ANALYZER] Developed by Hugen, Tinysa Ultra+ ZS406 installed with HW V0.4.6, with 4.0 inch 480*320 large touchscreen display, 100kHz to 5.4GHz widely measure range. And with the ESD protection function, the tinysa has a higher anti-static level and a longer service life. Built-in 32GB micro-SD card, solving the on-site data storage issue, convenient for data sharing and storage. [WIDELY FREQUENCY RANGE] Compared to the tinysa (100kHz to 960MHz), 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. [USB Interface Powered] The ZK09-BM is a USB-powered RF low noise amplifier, adds a battery and reduces power consumption, making it suitable for portable use. Ultra-broadband, Low noise. Good flatness in the 100k-10GHz range. Gain: 21dB, OP1dB: 13dBm Typ. Can be used to replace ADM-8095, ADM-8625 modules. [Built-in Battery] Built-in 300mAh battery, it has a flatter and more consistent gain, lower noise figure, smaller size, and longer battery life (Charging 210mA, Total 260mA, Battery life 5 hours). [Application] Recommended for use as tinySA ULTRA 5.8GHz preamplifier(Unless specifically requested, please avoid using both the built-in LNA and external LNA of tinySA ULTRA at the same time). For RF & Software Defined Radio (SDR). Notice:If there are differences in words, it will not affect the application.
