Description
Overview
GAOTek 100 kHz to 6GHz USB based Full 2-port Vector Network Analyzer is a USB based full 2-port vector network analyzer. 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. The ultra-low noise power supply design and the use of 16-bit ADC, together with the precision CNC’s aluminum shielded housing, achieve up to 100 dB of effective dynamics. Many aspects are already comparable to lab-grade VNAs, but this is still a work-in-progress project. Some design features may not be perfect, especially the performance will drop when the frequency is higher than 3 GHz, please fully understand the possible limitations before buying this machine.
