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).
