Measures low currents and high resistances quickly, accurately, and economically
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 . The Model 2502 is also designed to
increase the throughput of Keithley's LIV (light-
current-voltage) test system for production test-
ing 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 .
