Speeding up synchronization testing of telecom networks
The FTB-8080 Sync Analyzer is a comprehensive test solution for telecom network synchronization assurance, monitoring and troubleshooting applications. It can be used as a stand-alone instrument, controlled remotely via Ethernet, or operated from EXFO’s FTB-500 Platform. A complete suite of SCPI commands allow easy automation in manufacturing or lab testing applications.
The FTB-8080 offers a full range of wander and sync testing functionalities, including graphical display of TIE, MTIE and TDEV parameters, as well as comparison to ITU/ANSI/ETS standards and user-definable masks. The companion Sync View software suite allows remote data retrieval and test case setup, eliminating the need to visit test sites during prolonged monitoring periods. Easy to operate and maintain, the FTB-8080 Sync Analyzer prevents common measurement errors by offering automated signal detection. The internal rubidium clock is automatically calibrated when connected to a cesium or GPS reference signal, allowing adjustment in the field by untrained personnel.
Wander measurement
The FTB-8080 can measure both “absolute” and “differential” wander. In the first case, the measured signal (clock or data) is compared to the ultimate stability of the internal rubidium “atomic” clock or an external 10 MHz reference. In the second case, the relative wander between two signals (e.g., ingoing and outgoing E1 signal from a network element) is measured. This makes it possible to verify wander tolerance and the amount of “extra wander” created by the device under test. Measure absolute wander in sync equipment and network elements by using the internal rubidium clock as a reference, or using GPS satellite synchronization to compare multiple sites with a single reference, and correlating with SyncView software. Measure differential wander in/out of sync equipment and network elements by using the incoming sync signal as reference for the outgoing sync signal, accurately assessing wander added by equipment or network elements.
Remote control via internet
EXFO’s FTB-8080 is a compact, lightweight, self-contained instrument that features a built-in rubidium reference clock and a graphical display. There is no need to carry around an external frequency standard or a separate PC to make and view the measurement. A PC cable and 120 W to 75 W transformers come standard, to enable measurement on any kind of cable system, whether 75 W unbalanced or 120 W balanced. An Ethernet interface, a 1.544/2.048 MHz clock and a 48 V DC voltage supply also come standard.
Easy to operate and calibrate
The FTB-8080 is very easy to use and can be easily operated by unskilled personnel. For standard measurements, only a few keystrokes are required. Once the measurement is started, the unit can be left unattended for automatic measurements, and can be configured to automatically start and stop at preset times. A fully automatic signal check informs the user whether he/she has connected the right signal from the rack. Online context-sensitive help is also available. The calibration and adjustment of the internal rubidium clock is simple and fully automated. Connect a known reference signal from a cesium or a GPS-controlled rubidium clock, enter the calibration mode of the Sync Analyzer, and leave the unit overnight. The next morning, the FTB-8080 is perfectly adjusted, without any manual trimming required. EXFO’s FTB-8080 Sync Analyzer is easy to carry, with side handles and a flight-proof transport case (extra accessory).
