Upgraded AURSINC NanoVNA V2 PLUS4 Vector Network Analyzer, 4 inch Touchscreen, 50kHz-4.4GHz HF VHF UHF Antenna Analyzer Measuring S Parameters, SWR, Phase, Delay, Smith Chart with 3200mAh Battery

["[ADVANCED NANOVNA] The NanoVNA V2 Plus4 is a 4GHz Transmission/Reflection vector network analyzer, measuring the S11 reflection coefficient and S21 transmission coefficient of a high-frequency network. It features the latest version V2.4, with firmware updates available at: nanorfe .com/nanovna-versions.html","[ULTRA-WIDE FREQUENCY RANGE] AURSINC NanoVNA V2 Plus4 antenna analyzer provides a 50kHz–4GHz ultra-wide frequency range with improved precision and accuracy. Additionally, the V2 Plus4 does not use harmonics for measurements. The system dynamic range of this NanoVNA reaches 90dB (at 1GHz) and 80dB (at 3GHz)","[PERFORMANCE] Equipped with a 4.0-inch large touchscreen, you can flip the display (via Menu - Display - Flip Display). It features an all-aluminum alloy design for effective anti-interference. The scanning speed of the NanoVNA V2 antenna analyzer is 4 times faster (400 points/sec). With low temperature drift, the V2 Plus4 automatically corrects drift errors internally to achieve highly repeatable measurements","[SUPPORT PC CONTROL] Supports PC control via two applications (NanoVNA Saver / NanoVNA-QT), with software compatibility across Linux, Windows (7 or above), and Mac OS. The device supports S parameter export and scans over 1024 points (via NanoVNA-QT software).
