This vector network analyzer supports measurement frequency up to 50KHZ-1000KHZ, expandable up to 1.5GHz, the default setting is 1 GHz, and accurate measurement up to 1.35 GHz. The number of data points 101 sweep-period is about 1.9s, fast measurement. With wide dynamic ranges and with parameter storage functions. Added real part amplitude, imaginary part amplitude, resistance graph, and reactance graph line. Trajectory noise is low. Features: 4.3 inch IPS TFT display, 800 x 480 dots. Support measurement frequency up to 50KHZ-1000KHZ, expandable up to 1.5GHz, the default setting is 1 GHz, and accurate measurement up to 1.35 GHz. The number of data points 101 sweep-period is about 1.9s, fast measurement. With wide dynamic ranges and with parameter storage functions. Standard Type-C interface, 4000mAs battery capacity, with high charging speed. The output power of PORT1 is low and the damage power of PORT2 is higher. Fixed the S21 pass-through 0.3dB bias problem. Fixed a bug where the menu would not respond after marking all. Fixed a bug where a spuriouswave was displayed when the VSWR was . Added version and information query commands. Added real part amplitude, imaginary part amplitude, resistance graph, and reactance graph line. Trajectory noise is low.
