新货和二手货都是现货! 全新现货分别是单模:FVB-60B-B-E1 有一台,多模FVB-60B-D-E1有一台。 二手的是只有单模的FVB-60B-E1 FVB-60B-B89.....等有5台 FVA-60B光衰减器无论在实验室还是现场使用,性能都很好。它所具有的高性能指标(如从2.5到70 dB的线性度为±0.15 dB,分辨率为0.05 dB,重复性为±0.01dB)使得它成为各种应用的首选。有供用户使用的RS-232接口。 型号 FVA-60B-B FVA-60B-C FVA-60B-D FVA-60B-E 光纤类型(μm) 9/125 50/125 62.5/125 100/140 校准波长 (nm) 1310/1550 1300 最大衰减 (dB) 70 65 回损(dB)(典型值) 45 27 插入损耗(dB)(典型值) 2.5 电源 AC充电器/镍氢电池/9V碱性电池 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 FlexibilityThe 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 CapabilityOperate 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 WayThe 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 ApplicationsThe 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.
