Keithley吉时利2502皮安表

2510和2520-AT精密温控源表增强了吉时利对激光二极管的高速LIV(光强-电流-电压)特性测试的完整性。这两个50W功率双极性源表仪器,专门针对光通信网络的激光二极管模块的测试应用而设计的,用于保证被测试器件的严格控温。2510是第yi个专门创造出给光通信激光二极管测试所用的控温仪器,将吉时利的高速直流电源和精密测量能力集合在一起,形成对激光二极管模块的热电型制冷器即TEC的精确温度控制的能力。


主要特征:

  • 带直流测量功能的50W TEC控制器
  • 提供完全数字化PID控制
  • 激光二极管模块测试时的温度控制
  • 较宽的温度设置(-50℃至+225℃),高分辨率设置(±0.001℃),稳定性好(±0.005℃)
  • 支持多种温度传感器输入——热敏电阻、RTD以及IC传感器
  • 保持恒定的温度、电流、电压和传感器阻抗
  • 交流欧姆测量方法检测TEC的机械损坏
  • 控温时测量并显示TEC参数
  • 用于热反馈元件的四线开路/短路导通探测功能
  • IEEE-488 与 RS-232 接口
  • 紧凑的半机架式设计

详细信息

Features:

  • Dual-channel instrument for optical power measurements, beam measurements, and nanoscale materials and device research
  • ±100V source for bias requirements
  • Measure photodetector current from 1fA to 20mA
  • 1fA current measurement resolution
  • Measure optical power directly when used with Model 2500INT IntegratingSphere
  • 0-10V analog output for high resolution optical power feedback
  • Provides a high accuracy, high speed fiber alignment solution
  • Supports assembly process, final testing, parts binning, and specification
  • Allows faster alignment of the fiber with the laser diode-s optimum light emitting region
  • Combines fiber alignment and device characterization processes
  • User-programmable photodetector calibration coefficients
  • 3000-point buffer memory on each channel allows data transfer after test completion
  • Digital I/O and Trigger Link for binning and sweep test operations
  • IEEE-488 and RS-232 interfaces


Description

The Keithley 2502 Dual-Channel Picoammeter provides two independent picoammeter-voltage source channels for a wide range of low level measurement applications including laser diode testing. The Model 2502 is also designed to increase the throughput of Keithley's LIV (lightcurrent- voltage) test system for production testing of laser diode modules (LDMs). Developed in close cooperation with leading manufacturers of LDMs for fiberoptic telecommunication networks, this dual-channel instrument has features that make it easy to synchronize with other system elements for tight control over optical power measurements.


The Model 2502 features a high speed analog output that allows using the LIV test system at the fiber alignment stage of the LDM manufacturing process. Through the use of buffer memory and a Trigger Link interface that's unique to Keithley instruments, the Model 2502 can offer the fastest throughput available today for LIV testing of laser diode modules. These instruments are ruggedly engineered to meet the reliability and repeatability demands of continuous operation in round-the-clock production environments.
