产品介绍：
FVA-60B
Up to 65 dB attenuation Typical 2.5 dB insertion loss Automatic attenuation sequence with Program mode Standard Universal Interface Lab and Field Versatility This portable variable attenuator performs just as well in a laboratory environment as it does in the fi eld. Superior specifi cations make it the variable attenuator of choice for a number of applications. For lab or fi eldwork fl exibility, choose the FVA-60B. Total Flexibility Three attenuation display modes: Absolute (including insertion loss) Relative (in reference to 0.00 dB level) 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. Exceptional Specifi cations High-quality optical components make the FVA-60B Variable Attenuator the standard for performance and fl exibility. EXFO’s computer-assisted calibration techniques deliver remarkable specifi cations: ± 0.15 dB linearity 0.05 dB resolution ± 0.10 dB repeatability Multiple Applications The FVA-60B enables consistent operation in various manual or automated testing situations. BER testing System testing and acceptance Power meter calibration and verifi cation Optical margin analysis System loss simulation Field, manufacturing and R&D applications 如需要以上EXFO FVA-60B可调光衰减器 ，请与我司联系，我们的大多数设备在装运之前均经过严格的质量检测与校验。也可申请国家计量证书。
