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 fiberoptic 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.
Feature & Benefits:
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
Applications: Industrial, Maintenance & Repair, Test & Measurement
