Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•【4.3 inch Large Touch screen and powerful function】Handheld Vector Network Analyzer using 4.3-inch IPS TFT LCD screen, with a larger view angle and can be seen clearly in strong outdoor light.which can measure S-parameter, voltage standing wave ratio SWR, phase map, group delay, Smith chart and so on.
•【Higher Capacity Battery,and Longer Standby time】 Upgraded the large capacity 5000mA-h 3.7V battery, longer standby time, and extended USB interface. Typically, it can be used as a mobile power source to charge Android or Apple phones when not in use. The IC is charged by high current 2A, and the charging time is shorter.
•★【2022 Upgraded Professional LibreVNA】: The LibreVNA Antenna Analyzer provides a 100kHz to 6GHz ultra-wide frequency range(previous vna analyzers are about 10KHz-1.5/3GHz),New 6-layer PCB design optimizes the S12 port isolation and high-frequency port matching. The S12 can achieve over 90dB of port isolation below 3GHz, allowing measurements above 6GHz using harmonics. In actual tests up to 9GHz, both S11 and S22 have more than 10dB port directivity, and S12 S21 have more than 40dB dynamics.
•★【Comparable to Lab-grade VNAs】:LibreVNA is a USB based full 2-port vector network analyzer designed by Jankae. Using 3 ADCs to sample data simultaneously and using FPGAs for signal processing, it is capable of scanning over 10,000 points of full dual-port measurements in less than 1 second.This vector network analyzer will be a nice addition device to the workbench, which is a very fully functional analyzer for electronics engineer, amateur radio operators or radio diy enthusiast.
•★【Powerful Function & Firmware Update】:The ultra-low noise power supply design and the use of 16bit ADC, together with the precision CNC's aluminum shielded housing, achieve up to 100dB of effective dynamics. Many aspects are already comparable to lab-grade VNAs, but this is still a work-in-progress project.Support Firmware Update,can load a new microcontroller firmware and FPGA configuration into the LibreVNA. Do not disconnect power while updating the firmware!
