This handheld variable attenuator performs just as well in a laboratory environment as it does in the field. Superior specifications (±0.15 dB linearity from 2.5 to 70 dB, 0.05 dB resolution and ±0.10 dB repeatability) make it the variable attenuator of choice for various applications. For lab or field work flexibility, choose the FVA-60B Variable Attenuator.
Total Flexibility
The FVA-60B offers three attenuation display modes: Absolute (including insertion loss), Relative (in reference to 0.00 dB level) and x + b (arbitrary value). Program mode: Cycles through a repeatable sequence of up to 60 attenuation steps, pausing for one second or up to 60 hours at a time. The Program mode is particularly suited to accelerated bit-error-rate (BER) testing. Fourteen available wavelengths: Matches your source wavelength to the nearest 10 nm for unbeatable accuracy. Variable scanning speed: Scans the complete attenuation range at four different speeds according to the selected step size (0.05, 0.20 or 1.00 dB/step and variable step size).
Remote Control Capability
Operate the FVA-60B remotely from your PC using the standard RS-232 interface and control codes. Program software solutions are adapted to your testing needs.
Three-Way Powering Goes a Long Way
The FVA-60B features three complementary power sources for extended operation: a rechargeable NiCd battery, a 9 V alkaline backup battery and an AC adapter/charger for continuous operation.
Multiple Applications
The FVA-60B enables consistent operation in various manual or automated testing situations, such as BER testing, system testing and acceptance, power meter calibration and verification, optical margin analysis, system loss simulation, as well as field, manufacturing and R&D applications.
