Product Overview

The Model 2502 Dual-Channel Picoammeter provides two independent picoammeter-voltage source channels for a wide range of low level measurement applications including laser diode testing. 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 fibre optic telecommunication networks, this dual-channel instrument has features that make it easy to synchronise with other system elements for tight control over optical power measurements.
  • Dual-channel instrument for optical power measurements
  • ± 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 Integrating Sphere
  • 0–10V analogue output for high resolution optical power feedback
  • Provides a high accuracy, high speed fibre alignment solution
  • Supports assembly process, final testing, parts binning, and specification
  • User-programmable photodetector calibration coefficients
  • IEEE-488 and RS-232 interfaces
