Key Features
All-in-one to address multiple technologies
The EtherScope nXG has two sets of native Wi-Fi network interfaces: a 4x4 adapter that scan
and test Wi-Fi networks, and a 1x1 adapter for remote control connection and testing. Both
interfaces support 802.11a/b/g/n/ac and can show analysis of utilization and status of Wi-Fi
channels, SSIDs, BSSIDs, access points, client devices, and interferers. The EtherScope nXG
provides visibility of Wi-Fi 6 devices.
The EtherScope nXG has two Ethernet ports. The main test RJ-45 port supports Multi-Gig
networks from 10/100/1000Mbps to 2.5/5/10G to verify link speed SNR, and duplex advertised
and connected. It can request and verify PoE power under load from up to 90W PSE’s.
Alternatively, it can interface to fiber networks via single/multi-mode SFP+ to test 1/10Gbps
fiber-based Ethernet. The second RJ-45 management port connects to 10/100/1000Mbps
Ethernet for remote control, and conducts network scanning and tests where needed. It is also
the port for cable testing.

Simplifies tasks and empowers technicians to verify
complex networks with next generation AutoTest
The EtherScope nXG has out-of-the-box AutoTest profiles with best practice
pass/fail thresholds for quick assessment of network configurations and
services of Wi-Fi and wired networks.
Ethernet Network: switch port PoE characteristics, VLAN Tagged traic
detection, 802.1x authentication, link speed advertised vs negotiated,
DHCP/DNS/Gateway availability and accessibility.
Air Quality: assess number of APs, co-channel and adjacent channel
interference, and channel utilization
Wi-Fi Network: supports various authentication and security schemes
to connect to SSIDs/BSSIDs for coverage by signal/noise, and DHCP/DNS/
Gateway availability and accessibility.
Multiple profiles can be created for complex networks with multiple VLANs
supported per switch port, and Wi-Fi networks with multiple SSIDs each
with its own set of IP targets. These can then be organized into profile
groups that execute each test against each profile in sequence. The result
is that multiple VLANs, and SSIDs can be verified and documented in one
go. Since the pre-defined profiles can be executed individually, the profiles
group serves as a resource for technicians to verify each specific VLAN or
SSID during troubleshooting. With profile groups, engineers can transfer
their network configuration and test knowledge to technicians, saving
training time and eort.

24-Hour Monitoring for Intermittent Issues
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 eective way to “monitor” aspects of your network for
an extended period, or to help diagnose intermittent issues without having
to manually execute multiple tests. Results are automatically timestamped
and can be prefixed with a user-entered comment for grouping or
organization. Test results can be quickly analyzed in Link-Live using the
filtering and sorting functions. Email notifications can warn you when
errors are found.
A number of additional enhancements in version 1.2 expand the use models
for EtherScope nXG, provide more actionable information, and make the
network analysis process even more eicient. See the EtherScope nXG v1.2
release notes for additional information.
Multi-Gig Link Validation
With the expanding deployment of Multi-Gig switching (typically to feed
greater bandwidth to Wi-Fi 6 access points), users are finding that their
cable plant may not support the desired speed. Cable quality, length,
installation workmanship, and noise in the environment all can contribute
to “downshiing” to lower-than-expected speeds.
• Cabling SNR Measurement – EtherScope nXG can now verify copper
media for Multi-Gig capability (1 / 2.5 / 5 / 10Gig), and provide root
cause diagnosis when link speed downshiing occurs.

Wi-Fi AutoTest - Link Validation
The Wi-Fi AutoTest runs a series of tests by connecting to a selected wireless
network (associate to an AP), providing a status indication of Success,
Warning, or Fail. This comprehensive test validates not only the Wi-Fi
connection, but also each critical supporting network service.(Note: Wi-Fi
AutoTest supports connecting to Captive Portals where a sign-in is required
for access; see User Guide for instructions.)
Wi-Fi Link Test – validates the ability to connect to the selected network.
Drilling into the link test provides in-depth information about the SSID,
signal strength/SNR, channel utilization, retries, and PHY rate. Of note,
Roams indicates the Number of times the unit has disconnected from the
previous AP and connected to a dierent AP with a better signal strength.
The Wi-Fi Link Test graphs save and display data for up to 24 hours in the
past, providing a way to “go back in time” to identify specific problem
instances.
Channel Test – shows the channel on which the AP is operating and
the current 802.11 and non-802.11 utilization in real time, and plots
the percentage of channel capacity used by devices and non-802.11
interference.
AP Test – shows the AP name and SSID of the network it supports, its IP
and MAC addresses, security, channel (if the BSSID is on multiple channels,
the bold number indicates the primary), 802.11 types supported, and client
associations (number of clients connected to the AP).
Wi-Fi AutoTest
DHCP, DNS, Gateway Results – these validate the availability and
performance of critical network services via the Wi-Fi network. Diagnostics
on each test provide details on response times and logs for troubleshooting.
Path Analysis – can be run from the above network services tests to
identify the connection path to the specified service (or server); this is
useful to determine if errors or excessive utilization on the wired network
may be aecting the particular service.
Air Quality Test
The Air Quality Test performs a single scan of the channels in your wireless
network to measure channel utilization and interference.
Each table on the Air Quality results screen shows the top four channels in
each band with the highest utilization or co-channel interference, along with
the number of APs operating on the channel.
Channel Utilization and Interference
Quickly determine if channels are over-utilized with Wi-Fi traic and/or with
non-Wi-Fi interference and noise. You can also gain visibility on the level of
Wi-Fi traic and interference over the last 60 seconds on a selected channel,
as well as, the access points, clients, and interferers using this channel.
Drill into details and detect devices that can cause interference, such as,
microwave ovens, wireless game controllers, Bluetooth® devices, Zigbee
devices, and wireless video camera.
Automated Problem Detection
EtherScope nXG automatically diagnoses various conditions on both wired and
wireless networks and identifies specific problems. Tapping the Problems card shows
all discovered issues, which can be sorted by severity or time detected. Drill in to see
a detailed description of the problem and recommended course of action to mitigate.
