Features Wide Application: VNA vector network analyzer is very suitable for RF circuit matching and debugging of WiFi, 2.4G, 5.8G and GPS. It is used to measure the matching characteristics of passive and active radio equipment, such as antennas, cables, filters, attenuators, amplifiers, etc. Wide frequency range: 23MHz to 6200MHz wide operating frequency range, 0.25dB and 1.5° full frequency range, to achieve high-precision measurement. 3.2-inch touch screen: vector network analyzer with 3.2-inch color touch screen, high sensitivity, can quickly set scanning parameters and display measurement results, scanning speed up to 1000 points/sec Aluminum Alloy: The shell is made of aluminum alloy and takes the form of a mobile automatic instrument, which is light in weight and compact in structure. Multiple Displays: Ability to display up to 4 independent markers on all graphs for accurate evaluation of measured parameters. The vector network analyzer can display almost all possible reflection coefficient descriptions, measure cable faults and loss distances.
