High-quality components and meticulous calibration procedures make the FVA-3100 Variable Attenuator the instrument of choice for repeatable and accurate attenuation settings (up to 100 dB). The FVA-3100 meets system and component manufacturers need for component and system loss simulation, instrument calibration, power meter linearity measurement and spectral tuning. Its ultra-low insertion loss enables you to optimize the loss budget.
The FVA-3100 is configured for singlemode or multimode fibers. Use it as a stand-alone instrument or mounted on a 19-inch rack (optional).
Attenuation modes: Choose from three attenuation modes: absolute (including insertion loss), relative (in reference to the 0.00 dB level) or X+B (relative display to any selected reference value).
Monitor port: The monitor output port enables accurate power-level monitoring at the receiver end of your system.
Programmable & Remotely Controlable
Using the front-panel buttons, cycle through a repeatable sequence of up to 100 attenuation steps, with a dwell time of up to 1000 hours per step. The Program mode is ideal for automated bit-error-rate (BER) testing and linearity measurements.
The FVA-3100 can also be programmed remotely through its RS-232 or GPIB interfaces.
