Home Screen

Home Screen

The EtherScope nXG is the first Android-based WiFi and 10G wired network analyzer. It has a dedicated set of Ethernet and WiFi management interfaces which support remote control and additional testing. It has a BlueTooth/BLE radio, and Android apps downloaded from the Link-Live collaboration, reporting, and analysis platform can use these interfaces for testing and communication purposes.

As a light-weight, handheld, multi-function instrument, EtherScope is perfect for remote site validation and troubleshooting, eliminating the need to purchase multiple testers, and the need to carry a fragile laptop PC or tablet. Android apps make the user’s workflow more efficient by expanding the usage of the instrument beyond testing, allowing the user to check trouble tickets, run speed tests, configure networked devices, and complete other tasks with its smartphone-like features.

Auto Test
EtherScope AutoTest WiFi Profile


AutoTest is the most comprehensive NetAlly testing App on the EtherScope nXG. It allows you to quickly run a variety of test types and save their configurations and network credentials for access whenever you need them. The App is fully customizable with test “profiles” for wired and WiFi network connections, wireless air quality, and individual “test targets” that can run with any profile.

AutoTest allows engineers to transfer their knowledge of network configurations to the instrument, empowering frontline technicians to run tests against various wired VLANs and WiFi SSIDs with minimal training. The result is a repeatable, documented test with shortened overall test times, which otherwise would not be possible with other test methods.

Periodic AutoTest:
In this mode, AutoTest runs at specified intervals (from 1 minute to 24 hours) and sends the results to Link-Live to view the results over time. This is an effective way to “monitor” aspects of your network for an extended period, or to help diagnose intermittent issues without having to manually execute multiple tests.

Wired Network Test

Wired Network Test

The Wired Network Test profile verifies PoE Class voltage & loaded power, link speed, 802.1x authentication, shows VLANs supported, identifies nearest switch ports with CDP/LLDP/SNMP, tests for DHCP/DNS/Gateway response, and verifies connectivity (using Ping, TCP Connect, HTTP and FTP) to an unlimited number of test targets. Users can tap on each card to see more details and click the purple floating action button to attach the connection log, comments and photos of the environment (using EtherScope nXG’s built-in camera) to the test results.

With pre-programmed wired test profiles with Pass/Fail thresholds, and advanced VLAN visibility, it is easy for technicians to test various wired network configurations with minimal training. The test results, along with connection log, comments and images can be uploaded to Link-Live for automated documentation and analysis by remote experts.

WiFi Troubleshooting Tools
EtherScope AutoTest WiFi Profile

WiFi Troubleshooting Tools

The EtherScope nXG WiFi device discovery automatically detects problems. It shows possible cause(s) for each problem detected, and it has integrated WiFi troubleshooting tools to investigate further and get to root cause. Some of the tools included are:
Packet Capture: You can capture WiFi 6/6E traffic on the 2.4/5/6GHz bands to create a PCAP file of up to 1Gigabyte. Packet slicing and filtering are supported, and PCAP files can be uploaded to the Link-Live Cloud Service for easy sharing.

Connection Test: Verifies connection and authentication to selected SSIDs/BSSIDs on the 2.4/5/6 GHz bands. It checks the connected channel utilization, tests for DHCP/DNS/Gateway response, and validates connectivity (Ping, TCP Connect, HTTP and FTP) to an unlimited number of test targets.

Roaming Test: In the WiFi link test graphs (SNR, Utilization, Retries, PHY Tx Rate) as well as in active test graphs (PING), anytime the EtherScope roams and connects to a new AP, a red vertical line will be shown in the graph. Seeing the correlation between various factors and the roam can help diagnose roaming successes as well as failures.

Locate: Simplifies the process of physically locating both AP and Client devices on the 2.4/5/6 GHz band by measuring their signal strength. Making it easier to find rogues devices or locate APs that need to be replaced.

With its compilation of WiFi troubleshooting tools the EtherScope nXG makes it quick and simple to identify the root cause of WiFi network problems.

WiFi Channels Map

The WiFi channels map provides a visual representation of 802.11 utilization and non-802.11 utilization for each channel on the 2.4/5/6 GHz bands. It also shows number of APs, number of Clients, and retry percentage for each channel.

Quickly determine if channels are over-utilized with WiFi traffic and/or with non-WiFi interference and noise. You can also gain visibility on the level of WiFi traffic and interference over the last 60 seconds on a selected channel, as well as the access points and clients using this channel.

WiFi Device Details
EtherScope AutoTest WiFi Profile

WiFi Device Details

The EtherScope nXG automatically discovers your network through its dual set of WiFi radios immediately upon power-up. The discovery provides quick security and health audits of the network devices across all WiFi channels.
Devices are classified and correlated to provide complete visibility of their name, network addresses, SSID, device type, and where available, traffic statistics. Engineers can name and set authorization status for devices discovered. Discovery results can be directly uploaded to the complimentary Link-Live Cloud Service for storage, conduct detailed analysis of devices discovered with filter and sort tools, or export to CSV/PDF files as documentation.

The EtherScope correlates the discovery result from the wired and WiFi networks and breaks the layer 2 visibility ceiling. EtherScope nXG makes it easy to discover the actual identity of a WiFi device by showing its a name and IP address while most other WiFi tools only show the MAC address.

Path Analysis

Path Analysis

Path Analysis traces the connection points, including intermediate switches and routers, between the EtherScope nXG (connected over WiFi or Ethernet) and a destination URL or IP address. Path Analysis uses SNMP queries to identify issues such as overloaded interfaces, overloaded device resources, and interface errors. It also shows how devices within your network (and off-net devices) are connected.

The Path Analysis app can test through any one of the four network interfaces that have established a connection to the network and have an IP address.

EtherScope nXG has the unique ability to break through the “visibility ceiling” between WiFi and wired networks, showing who and what is on your network, where they are connected, and their path across your network.


AirMapper™ Site Survey for WiFi and Bluetooth/BLE

With AirMapper, EtherScope nXG users can quickly and easily gather location-based WiFi and Bluetooth/BLE measurements and create visual heat maps of key performance metrics in the Link-Live collaboration, reporting, and analysis platform.

The EXG-300, an improved version of the EtherScope nXG with a native WiFi 6/6E radio, allows you to perform both active and passive WiFi 6 surveys on the 6 GHz band.

Import a floor plan image (.png or .jpg) and calibrate the floor plan dimensions (in meters or feet). Or, automatically push pre-configured and calibrated floorplans from Link-Live to testers in the field. Then touch START to collect data. Tap at various points on your floor plan to collect data; comments can be added to the survey with a long tap on the floorplan. When done, tap STOP, then touch the save icon to send your results to Link-Live for sharing and analysis.

Faster and easier than using site survey software on a laptop or tablet with an attached dongle or tethered device, AirMapper is ideal for quick site surveys of new deployments, change validation, and performance verification. The ease and portability of this solution enable technicians to quickly troubleshoot or validate the WiFi and Bluetooth networks by measuring the real-world experience of mobile device users.



The EtherScope nXG’s Performance app provides point-to-point performance testing of a UDP traffic stream through its wired network interface against up to eight NetAlly hardware/software endpoints. This test quantifies network performance in terms of target throughput rate, loss, latency, and jitter at a specified throughput.

iPerf testing is available to test the network throughput for TCP/UDP streams over the EtherScope nXG’s WiFi or wired interface to an iPerf v3.0 server, such as the NetAlly Test Accessory.

The Performance and iPerf apps verify SLA of critical network links when deploying NBASE-T or 1/10G links to support critical device, e.g. 10G servers, network-attached-storages, and high-speed WiFi access points, ensuring you’re getting the bandwidth you expect.


LANBERT™ Media Qualification App

“Trillions of frames can’t be wrong.”

The LANBERT media qualification app for NetAlly’s multi-function professional instruments provides a simple and fast method of assessing the quality of transmission and available bandwidth in your copper and fiber cable plant. LANBERT generates and measures the transmission of line rate Ethernet frames over your network cabling infrastructure, qualifying its ability to support 1G/10G on fiber and 100M/1G/2.5G/5G/10G on copper links. (Test requires two instruments, two EtherScope nXG units, two LinkRunner 10G units, or one of each)

With the insatiable growth in bandwidth, increasing speeds of WiFi APs (with Multi-Gig 2.5/5Gbps backhauls), 1Gbps to 10Gbps upgrades, and deploying new fiber links, network professionals must have confidence that their network will transport that data error-free at the maximum speed possible. LANBERT allows you to maximize the utilization of your existing cabling, preventing unnecessary cabling upgrades.


Spectrum Analysis

Trying to pinpoint the source of WiFi interference on a wireless network is hit or miss with the wrong tools. Using the optional NXT-1000 Mobile Spectrum Analyzer, EtherScope nXG offers a view of RF interference in the 2.4 and 5.0 GHz bands and its impact on the wireless network’s overall performance. Key graphs and charts include:

- Real-Time FFT - Provides a real-time view into the RF environment.
- Spectrum Density – Displays real-time analysis on signals that are common during the current capture session.
- Spectrogram - Shows intermittent spikes of RF energy that may be causing wireless network problems.

Simplify interference troubleshooting and location by providing visibility into the 2.4GHz and 5.0GHz spectrum bands, plus secure the WiFi network by inspecting No Wireless Zones and detecting and locating intentional RF interference sources such as RF jammers.

Native WiFi 6 and 6 GHz Support

With the introduction of WiFi 6/6E the way WLAN validation and troubleshooting is done has changed. New technologies designed to improve traffic management efficiency and support for the 6GHz band were introduced, allowing for higher throughput and better performance in environments where a high user capacity is required – necessitating new technology to test and validate these networks.
