The Model 2510 TEC SourceMeter instrument enhances Keithley's CW (Continuous
Wave) test solution for high speed LIV (light-current-voltage) testing of laser
diode modules. This 50W bipolar instrument was developed in close cooperation
with leading manufacturers of laser diode modules for fiberoptic
telecommunications networks. Designed to ensure tight temperature control for
the device under test, the Model 2510 was the first in a line of highly
specialized instruments created for telecommunications laser diode testing. It
brings together Keithley's expertise in high speed DC sourcing and measurement
with the ability to control the operation of a laser diode module's Thermo-Electric
Cooler or TEC (sometimes called a Peltier device) accurately.
