Updates and Bug Fixes

v5.00

Updated: September 10, 2026

A security update for critical vulnerability is included. We recommend immediately updating your X240, X240i, X500, X500e, and X700 analyzers with this release. Read the full Security Advisory Notice.

What’s new

Introducing Frontline X700, a one-box solution for simultaneous, time-correlated capture of Bluetooth in the 2.4 and 5/6 GHz bands, Wi-Fi 7 MLO 802.11be, 802.15.4, and wired technologies.

Key Features

  • Bluetooth Analysis

    • Supports Bluetooth BR/EDR and LE.

    • Hardware-ready for emerging Bluetooth modulation schemes in higher-frequency bands.

    • Bluetooth Channel Sounding PHY support planned shortly after initial release.

    • Contact us regarding HDT PHY support availability.

  • Wi-Fi 7 Multi-Link Operation (MLO)

    • Supports 2x2 Wi-Fi 7 (802.11be) MLO operation across the 2.4 GHz, 5 GHz, and 6 GHz bands.

    • Simultaneously captures and correlates traffic on up to three Wi-Fi channels.

  • IEEE 802.15.4 Support

    • IEEE 802.15.4 capture support planned shortly after initial release.

  • Integrated Spectrum Analysis

    • Simultaneous spectrum capture in the 2.4 GHz ISM band and 5 GHz U-NII-1 band.

    • Expanded support for additional 5 GHz and 6 GHz bands, including U-NII-3, U-NII-4, and U-NII-5, planned for the next release.  Contact us for early access now.

  • Wired Interface Correlation

    • Supports HCI-UART, HCI-USB, I²S, and WCI-2 interfaces.

    • Enables end-to-end visibility by correlating over-the-air and wired communications.

  • Logic Analysis

    • Captures up to 24 digital signals using three logic pods for comprehensive system debugging.

  • Audio Analysis

    • Supports the Audio Analyzer Pod for audio quality assessment and latency measurements.

  • Advanced Gain Control

    • Provides both Automatic Gain Control (AGC) and Manual Gain Control for Bluetooth radio capture.

    • AGC is enabled by default to simplify setup while ensuring reliable packet capture across varying signal conditions.
