AEM Network Service Assistant (NSA) is a revolutionary next-generation multifunction network qualifier that bridges the gap between a basic cable tester and a full structured-cabling certifier. Using patented Certi-Lite technology – compliant with ANSI/TIA-1152-A – the NSA runs advanced single-ended CAT3–CAT6A channel tests with a complete set of electrical measurements: IL, RL, NEXT, PSNEXT, ACRF, PSACRF and TDR analysis. It is the only device in its price class combining copper cabling qualification+, SM/MM fiber testing with OTDR, PoE measurement up to 90 W (802.3bt), Multi-Gig SNR analysis up to 10 Gigabit Ethernet and Wi-Fi network diagnostics at 2.4/5 GHz – all in a single, portable device.
Many organizations ask themselves: when is cabling qualification enough, and when is full LAN certification essential? The answer depends on project requirements and the warranties needed.
The NSA combines eight main test functions in one platform with hot-swap interchangeable adapters. Below is a full overview of its capabilities:
Certi-Lite is the NSA’s flagship measurement technology: a single-ended channel test of CAT3, CAT5e, CAT6, CAT6A copper cabling compliant with ANSI/TIA-1152-A. ALI (Advanced Link Identification) remote terminators placed at the far end of the cable let a single technician run the full electrical test – without needing a second full-featured instrument at the other end of the run.
The Certi-Lite test result is presented as a clear PASS / FAIL broken down by individual parameter, allowing you to quickly identify and locate the problem. The NSA automatically indicates whether the tested channel can support the required network application – from Fast Ethernet to 10 Gigabit Ethernet.
Measured Certi-Lite parameters (PASS/FAIL criteria):
Typical Certi-Lite test applications:
ALI (Advanced Link Identification) remote terminators used for NSA Certi-Lite tests take installation diagnostics to a whole new level. The Live Wiremap function with numeric identifiers – up to 8 different IDs – lets a technician instantly sort out cables that were not properly labeled or were incorrectly terminated.
The wire pair map is displayed in real time the moment a remote terminator is detected – without running a full Autotest. Studies show that a significant share of structured cabling failures stem precisely from wiremap errors (reversed pairs, split pair, crossed links). The NSA detects and graphically reports all of these errors instantly.
The NSA features three specialized fault locators based on TDR (Time Domain Reflectometry) technology, enabling precise location of the fault along the cable run – to within a meter. It is an essential tool for diagnosing CAT6A-class LAN networks in smart buildings, data centers and corporate campuses.
RL Locator – locating Return Loss faults
Return Loss faults can be hard to diagnose – they may result from faulty RJ-45 connectors, poor cable quality, too tight a bend radius or a kink in the cable. The NSA provides RL-specific TDR analysis, pinpointing the exact location of the worst RL fault on the link – dramatically cutting repair time.
NEXT Locator – locating crosstalk faults (Near-End Crosstalk)
NEXT problems appear with faulty connectors, incorrect pair twist, daisy-chained connections or excessive untwisting of the cable pairs. The NEXT Locator TDR precisely indicates the fault location along the cable run, allowing it to be effectively fixed without dismantling the whole installation.
Shield Locator – locating shield breaks in F/UTP, S/FTP, U/FTP cables
Shielded cabling (F/UTP, SF/UTP, U/FTP, S/FTP) requires shield continuity along the whole channel length to meet CAT6A requirements. The Shield Locator TDR makes it possible to identify breaks, discontinuities or shield problems, giving the exact distance to the fault. An essential tool for installations in high electromagnetic interference (EMI) environments.
The NSA supports the full range of Power over Ethernet standards: IEEE 802.3af (15.4 W), 802.3at Type 2 (30 W), 802.3bt Type 3 (60 W), 802.3bt Type 4 (90 W) and Cisco UPoE. PoE Load Testing includes:
PoE test applications: IP camera (CCTV) installations, VoIP phones, wireless access points (Wi-Fi APs), access control systems, BMS/IoT sensors, information displays, smart building controllers.
The NSA runs a Multi-Gig SNR Autotest for 100 Mbps, 1 GbE, 2.5 GbE, 5 GbE and 10 GbE speeds – verifying the real ability of the cable channel to support a given transmission rate under real traffic and PoE load. SNR (Signal-to-Noise Ratio) is measured under active network traffic, giving reliable results in production conditions.
NSA network diagnostic functions:
Wireless Wi-Fi network diagnostics (2.4 GHz and 5 GHz):
With the optional AD-NSA-SM-01 / AD-NSA-MM-01 fiber adapter, the NSA becomes a complete tester for both single-mode (SM) and multimode (MM) fiber cabling. The adapter equips the NSA with a dual light source for loopback testing, and the results automatically report the supported network speeds.
NSA Fiber Test – SM and MM loopback:
OTDR adapters – optical reflectometry:
Fiber endface inspection:
Connector contamination is one of the leading causes of problems in fiber networks. The PROBE-FIBER-INSP inspection probe, connected to the NSA’s USB port, allows visual inspection of SC, LC, FC, ST connectors and identification of contamination or core/cladding scratches that can degrade the signal or damage active equipment.
The NSA also has a built-in VFL (Visual Fault Locator) – a visual fault locator emitting red 650 nm light, enabling cable tracing and location of fiber breaks or bends.
The NSA is available in four kit configurations differing in the range of accessories included. All kits contain the NSA platform, the AD-NSA test adapter, a Remote ID#1 remote terminator, a CAT6A coupler, a USB drive with documentation, a USB cable and a power supply with adapters.
All Certi-Lite, PoE, Multi-Gig SNR, network and fiber test results from the NSA are stored in internal memory and can be transferred to TestDataPro (PC) software or to the free TestDataPro Cloud platform. Transfer is possible via USB flash, USB Micro cable, LAN or Wi-Fi.
