AEM TestPro CV100
multifunkciós kábelanalizátor

A TestPro Autoteszt gombját megnyomva a műszer az összes TIA/ISO szabvány által megkövetelt paramétereken túl például a TCL-t is képes mérni.

Az átfogó DC ellenállás mérési tudásának köszönhetően képes vizsgálni az erek és érpárok közötti ellenállás különbséget is, ami a megfelelő PoE működés alapfeltétele. Hibás teszt esetén a grafikonos megjelenítésnek köszönhetően könnyen behatárolható a hiba helye, legyen szó az árnyékolás szakadásáról, NEXT vagy reflexiós hibáról. Egy Cat6A-s Channel vagy Permanent Link mérés mindössze 6 másodpercig tart.

A mérési eredmények elmenthetők a műszerre, majd az ingyenes TestData Pro szoftverrel elkészíthető a jegyzőkönyv.

A felmérések szerint az egyik leggyakoribb de viszont könnyen javítható probléma a huzaltérkép hiba. A TestPro fő és távolvégi műszerei a csatlakoztatás után felhasználói beavatkozás nélkül azonnal megjelenítik a huzaltéképet. A hiba helyének pontos meghatározásához csupán a huzaltérkép ábrára kell koppintanunk.

Az egyérpáras ethernet (SPE) használata gyorsan terjed az IoT szenzorok és egyéb eszközöknek köszönhetően. A TestPro az első olyan kábel minősítő műszer, amely képes az SPE rendszerek mérésére.

TestPro validates a cabling link for high performance Ethernet standards including 1 / 2.5 / 5 / 10GBASE-T. End-to-end Signal to Noise Ratio (SNR) measurement provides a quick and objective assessment of link performance under network load condition. The Autotest feature of the TestPro is the easiest way to ensure that a cabling link will the desired network rate.

Wireless access points (APs) are one of today’s most broadly deployed IoT devices and 802.11ac Wave 2 wireless APs require 2.5 and 5 GigE backbone speeds to run at maximum performance. Additionally, these devices can be PoE powered and by the nature of the link speed, require all four pair to be terminated. TestPro can certify the cabling infrastructure in accordance with TIA standards, verify link speed in accordance with IEEE 8023.bz specific to 1 / 2.5 / 5 / 10GigE, and verify loaded PoE++ in accordance with IEEE 802.3bt to 90W, as well as the lower power levels for IEEE 802.3at/af and UPoE.

Both TestPro and Network Service Assistant (NSA) provide a comprehensive test function for verifying PoE deployments up to 90W. UPoE and all PoE standards are supported, which include 802.3af/at/bt. The PoE source is tested with actual load connection. TestPro and NSA offer the unique ability to test internal and external load test over a sustained time period to validate the maximum power a PoE link can support. TestPro and NSA will also check that the cable installation meets the required power to turn on a PoE devices.

In addition to operational tests on PoE, the tester enables characterization of cabling links for DC Resistance Unbalance parameters in accordance with the latest TIA 1152A standard for certification testing. This can be done as a one-off test, or included in a cable certification with TestPro, or a Qualification+ / Certi-Lite testing with NSA. For TestPro, the complete Autotest including all standards certification test parameters in addition to added parameters is still 6 seconds for CAT6A!

When performing a PoE test, a remote tester is not needed as you are testing directly into the switch. In this case, you may convert your TestPro Remote into a Main under Setting/Device Type and deploy each tester individually to perform these tests.

PSE detection
Voltage: Voltage drawn by the PD
PSE Type: 1-2, 2, 3-4, and 4 –different types have different allocated power
PD Class: 0-8 –different classes have different allocated power
PoE Cable Pairs: Cable pairs used to transmit electrical power
Allocated Power: Power allocated for the PD
Real Power: Power when internal or external load is used
Internal and External Load Tests:

Voltage
Current
Real Power: The actual power available at the endpoint when a device draws power (load) through the PoE circuit. This can be measured using the tester’s internal load or using an external load.

When a cable is used for PoE, it is important to ensure that DC resistance of all wires is closely matched. Differences of resistance between pairs, or between wires within a pair can cause degradation in RF performance, inadequate PoE power delivery, or excessive heating. TestPro’s 6-second autotest includes full characterization of DC resistance parameters, including loop resistance, resistance unbalance in each pair, along with all combinations of pair-to-pair resistance unbalance.

An ideal network cable pair has 100 ohm impedance along the entire length. In reality, the impedance varies from 100 ohm in different amounts along the cabling link, the deviation being more significant at the positions of connectors. RL locator plot provides a view of the cable along its length. The locations of peaks in the RL Locator are representative of spots with poor impedance control. When a cable fails autotest, the RL locator helps determine the location along the cabling link that is most likely to have caused failure.

This is a great aid for trouble-shooting. With accurate location information of the problem spot, a technician can focus on fixing the issue on that part of the cable, whether it is the result of:

Impedance mismatch in components (non-compliant or damaged cable, inadequate cabling installation practices, too much tension on cables, kinks or non-compliant connecting hardware/patch cords
Improper termination practices (pair twist not maintained, excessive cable sheath removal)
Incorrect or substandard components (all cable & connecting hardware must be of same category/class/quality)

Unique to AEM field testers, is the ability to get a TDR trace of shield continuity. For shielded cable applications, being able to find the distance to where the shield continuity has been compromised is critical. Combination of impulse TDR and step TDR traces make it easy to find even small problems with the shield. Testers which only measure basic shield continuity will not detect a compromised shield issue like a “partial discontinuity” (a small part of the shield is still maintaining contact, but it has been otherwise damaged/compromised/not fully connected).

Shield Discontinuity alert will be indicated on Wiremap after the test, with an indication of distance to the event, the user can then go to the Shield Locator tool to view the TDR trace of the shield, with a clear indication of the location of the discontinuity.

In the traditional enterprise network installation, the primary objective was to provide cabling channel from the computers in the work-area to the telecom room. This is almost always achieved with:

Permanent link consisting of wall-mount jacks at one end of the cabling and patch panel at the other
Patch-cords to connect networking end-points to jacks/panels at both ends, wherein the entire cabling including the patch-cords (but not the plugs at the end-point connections) is referred to as channel.

Increasingly, the networking end-points are devices other than computers, and connecting them calls for adaptation in cabling topology. Devices such as IP security cameras have built-in jack for network connection. In order to cater to installation of these devices, a new topology is now accepted by the standardization bodies. This new topology, Modular Plug Terminated Link (“MPTL”) is a variation of permanent link where one of the ends is terminated into a plug.

Resist the urge to test MPTL cabling using Channel Adapters at the remote end, as Channel adapters do not characterize the modular plug, which defeats the purpose of testing this type of cabling. The only way an MPTL can be properly and accurately tested is with an adapter that uses the specific centered socket required for certification of plugs in the specific cabling category. For this reason, you will need to use a Patch Cord adapter rather than a Channel adapter and use MPTL test limit settings.

Note: Patch Cord Adapters MUST be the same category as the cabling system under test. Optional adapters needed: AD-5E-PCORD, AD-6A-PCORD and AD-6-PCORD adapter pairs.
