Chelegance SV6301A VNA 1MHz–6.3GHz Network Analyser

The Chelegance SV6301A is a portable dual-port vector network analyser covering 1 MHz to 6.3 GHz. Its extended SHF coverage makes it suitable for antenna development, RF engineering and component testing across HF, VHF, UHF and microwave applications.

The SV6301A supports S11 and S21 measurements for antennas, coaxial cables, filters, duplexers, couplers, attenuators, amplifiers and matching networks. Its wide measurement range also supports work involving Wi-Fi, Bluetooth, GPS and other higher-frequency RF systems.

7-inch touchscreen and practical controls

A high-brightness 7-inch IPS capacitive touchscreen with 1024 × 600 resolution provides a clear view of traces, markers and measurement results. Physical buttons complement the touchscreen for convenient bench and field operation, while the metal enclosure and folding rear stand provide a stable working platform.

Advanced RF measurements

Supported display and analysis formats include VSWR, Smith chart, Log Mag, linear magnitude, phase, group delay, Q factor, polar display and TDR. The built-in TDR function can assist with cable-length measurement and transmission-line fault diagnosis.
