Feature: 1. [FOR RADIO EQUIPMENT] Used to measure the matching characteristics of passive and active radio equipment, such as antennas, cables, filters, attenuators, amplifiers, etc. 2. [WIDE FREQUENCY RANGE] 23MHz to 6200MHz wide operating frequency range, full frequency range 0.25 dB and 1.5??, to achieve high accuracy measurement. 3. [3.2IN TOUCH SCREEN] With 3.2in color touch screen, can quickly configure scan parameters and display measurement results, scan speed up to 1000 points/sec. 4. [INDEPENDENT MARK] Ability to display up to 4 independent markers on all graphs for accurate evaluation of measured parameters. 5. [MULTIPLE DISPLAYS] Can display almost all possible reflection coefficient descriptions, measure cable faults and loss distances. 6. [WIDE APPLICATION] The vector network analyzer VNA is very suitable for radio frequency circuit matching and debugging of Bluetooth, WiFi, 2.4G, 5.8G, and GPS. 7. [ALUMINUM ALLOY] The shell is made of aluminum alloy and adopts the form of a mobile automatic instrument, which is light in weight and compact in structure.
