Network testing device Fluke Networks EtherScope nXG EXG-300 — tri-band Wi‑Fi (2.4/5/6 GHz), RJ-45, USB-A/C, battery-powered, 5 inch LCD

Fluke Networks EtherScope nXG EXG-300 is a handheld network testing and diagnostics instrument designed for technicians and engineers working on modern wired and wireless access networks. The device supports tri-band Wi‑Fi (2.4 / 5 / 6 GHz), wired Ethernet interfaces including RJ‑45 and SFP+/10G testing, and USB Type‑A and Type‑C connectivity. A 5" 720×1280 LCD provides on‑site visibility for surveys, packet captures, link tests and topology inspection. Battery power with a 100–240 V AC adapter option enables field operation for deployment validation, troubleshooting and site readiness checks.

Advantages

The EtherScope nXG EXG-300 combines WiFi 6/6E surveying, Bluetooth/BLE analysis and Ethernet link testing in a single portable instrument, reducing the need to use multiple separate tools. It supports advanced testing applications, automated topology discovery and integration with Link‑Live for centralized test data and reporting. The unit can verify Ethernet link performance up to 10G, perform media qualification tests to check cabling suitability for higher speeds, and run active and passive wireless surveys for coverage and client performance assessment. Rugged handheld hardware and Android‑based apps streamline field workflows and collaboration between remote and on‑site teams.

Suitable for

• Field technicians performing site surveys and WiFi 6/6E validation
• Engineers verifying Ethernet link performance and cabling qualification
• Security auditors checking wireless threats and network visibility
• IT teams documenting multi‑VLAN and multi‑SSID deployments
• Remote troubleshooting where collaboration and test data sharing are required

Key specifications

• Wireless: tri‑band support 2.4 GHz / 5 GHz / 6 GHz for Wi‑Fi 6/6E testing
• Wired interfaces: RJ‑45 Ethernet and SFP+ support for up to 10G link testing
• USB: Type‑A and Type‑C ports for device connectivity and peripherals
• Display: 5 inch LCD, 720 × 1280 resolution for on‑site analysis and visual reports
• Power: rechargeable Li‑ion battery with external 100–240 V AC adapter support
• Protocols and features: active/passive WiFi site survey, packet capture, LANBERT media qualification, topology discovery and Link‑Live integration

How to use

Power on the EtherScope nXG EXG-300 and select the appropriate testing app from the Android‑based interface for the task at hand: WiFi site survey, Ethernet link test, packet capture, or Bluetooth/BLE scan. Connect to wired links via the RJ‑45 or SFP+ port for throughput and LANBERT testing, or perform wireless scans and active/passive surveys using the internal radios. View results on the 5" display and save or upload test sessions to Link‑Live for centralized reporting, topology generation and team collaboration. Use included adapters and the USB ports for accessory connections and data export.

Recommendations

For consistent results, fully charge the battery before extended field use and keep the device firmware and apps updated via Link‑Live. When performing WiFi 6/6E surveys, plan both active and passive measurements to capture client performance and spectrum conditions; consider using the optional portable spectrum analyzer adapter for detailed RF interference analysis. For wired tests, use LANBERT media qualification to assess cabling capability prior to validating high‑speed links.
