Note: The Chelegance JNCRadio VNA 4.4GHz Vector Network Analyzer requires a USB-A to USB-C cable for charging. A cable with USB-C connectors on both ends may not be compatible with the unit’s charging system, which could explain the lack of response when connected.
- 50kHz - 4.4GHz Wide Frequency Range:Covers a broad frequency spectrum from 50kHz to 4.4GHz with a fast sweep speed of 400 points/s. It is perfectly suited for testing MF/HF/VHF/UHF antennas, including Shortwave, Wi-Fi, Bluetooth, and GPS applications.
- 7-Inch High-Definition Capacitive Touchscreen:Features a large 7-inch IPS LCD display with a resolution of 1024x600 and capacitive touch control. The bright screen ensures clear visibility even in outdoor environments, while the touch interface combined with 4 physical buttons offers intuitive operation.
- Professional RF Performance & TDR Function:Provides excellent dynamic range (S21 up to 70dB, S11 up to 50dB) for precise component testing. It also supports Time Domain Reflectometry (TDR) for measuring cable length and locating break points.
- Built-in 8GB Storage & Easy Data Export:Comes with a built-in 8GB memory card to store calibration states, .snp files, and screenshots. It functions as a virtual USB drive when connected to a PC via USB-C, allowing drag-and-drop file export without driver installation.
- Robust Metal Shielding & Long Battery Life:Designed with a CNC metal case to effectively shield against external electromagnetic interference. Powered by two built-in 18650 batteries (6700mAh total), it supports up to 4 hours of continuous operation and USB-C charging.
