Product Overview
The Models 2510 and 2510-AT TEC SourceMeter SMU instruments enhance Keithley’s CW (Continuous Wave) test solution for high speed LIV (light-current-voltage) testing of laser diode modules. These 50W bipolar instruments were 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.
The Model 2510-AT expands the capability of the Model 2510 by offering autotuning capability. P, I, and D (proportional, integral, and derivative) values for closed loop temperature control are determined by the instrument using a modified Zeigler-Nichols algorithm. This eliminates the need for users to determine the optimal values for these coefficients experimentally. In all other respects, the Model 2510 and Model 2510-AT provide exactly the same set of features and capabilities.

| Features | Benefits |
| Active temperature control | Prevents temperature variations that could cause the laser diode’s dominant output wavelength to change, leading to signal overlap and crosstalk problems. |
| 50W TEC Controller | Allows for higher testing speeds and a wider temperature setpoint range than other, lower-power solutions. |
| Fully digital P-I-D control | Provides greater temperature stability and can be easily upgraded with a simple firmware change. |
| Autotuning capability for the thermal control loop (2510-AT) | Eliminates the need to use trial-and-error experimentation to determine the best combination of P, I, and D coefficients. |
| Wide temperature setpoint range (–50°C to +225°C) and high setpoint resolution (±0.001°C) and stability (±0.005°C) | Covers most of the test requirements for production testing of cooled optical components and sub-assemblies. |
| Compatible with a variety of temperature sensor inputs—thermistors, RTDs, and IC sensors | Works with the types of temperature sensors most commonly used in a wide range of laser diode modules. |
| AC Ohms measurement function | Verifies the integrity of the TEC device. |
| 4-wire open/short lead detection for thermal feedback element | Eliminates lead resistance errors on the measured value, reducing the possibility of false failures or device damage. |
