Additional Features: 50W TEC SourceMeter Fully digital P-I-D control Designed to control temperature during laser diode module testing Compatible with a variety of temperature sensor inputs-thermistors, RTDs, and IC sensors Maintains constant temperature, current, voltage, and sensor resistance AC Ohms measurement function verifies integrity of TEC Measures and displays TEC parameters during the control cycle 4-wire open/short lead detection for thermal feedback element IEEE-488 and RS-232 interfaces Compact, half-rack design Accessories supplied: User's Manual, Input/Output Connector The 2510 TEC SourceMeter instrument enhances Keithley's CW (Continuous Wave) test solution for high speed LIV (lightcurrent- 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.
