Description
2026 LibreVNA Vector Network Analyzer 100kHz-6GHz Spectrum Analyzer 6-Layer PCB V1.6.5 Firmware Support
Upgrades:
* Upgraded 6-layer RF-dedicated PCB with independent RF ground shielding layer, segmented power distribution zones, and fully isolated receive signal paths for each port
* S12 isolation performance reaches >90dB within 3GHz, significantly reducing reverse signal leakage
* Latest 2026 hardware supports V1.6.5 firmware and GUI version updates
Features:
* 3-in-1 RF Test Platform (VNA + Spectrum + Signal Source): Integrates Vector Network Analyzer, limited Spectrum Analyzer, and Signal Generator functions in one device, enabling full RF workflow coverage from signal generation to network analysis.
* 2026 Upgraded 6-Layer RF Architecture: Built on a newly optimized 6-layer RF-specific PCB with independent shielding and segmented power distribution.
* Ultra-High Isolation Performance (＞90dB at <3GHz): Advanced RF isolation design dramatically reduces reverse leakage and interference. Achieves S12 isolation greater than 90dB below 3GHz, ensuring cleaner and more accurate measurement results in complex RF environments.
* Wideband 100kHz-6GHz Measurement Capability: Supports full S-parameter analysis (S11, S21, S12, S22) with measurement of VSWR, impedance, insertion loss, and reflection characteristics. Configurable up to 4501 points with fast sweep speed (<500ms).
* Stable Hardware + Open Software Ecosystem: Equipped with heat-dissipating metal enclosure, stainless steel flange SMA connectors, USB Type-C interface, and LibreVNA-GUI V1.6.5 (English). Compatible with Windows/Linux/macOS and continuously updated via open-source community.
