Product Description:
The 2520-AT precision temperature control source meter enhances the integrity of Keithley's high-speed LIV (light intensity-current-voltage) characteristic test of laser diodes. These two 50W power bipolar source meter instruments are specially designed for the test application of the laser diode module of the optical communication network, and are used to ensure the strict temperature control of the device under test. 2510 is the first temperature control instrument specially created for optical communication laser diode testing. It combines Keithley's high-speed DC power supply and precision measurement capabilities to form an accurate thermoelectric cooler for laser diode modules, that is, TEC. The ability of temperature control. The 2510-AT expands the 2510's performance through the auto-tuning function. By adopting the improved Zeigler-Nichols algorithm, the instrument can obtain the P, I, D (proportional, integral, and derivative) values of closed-loop temperature control. Therefore, users no longer need to determine the optimal values of these coefficients through experimental methods. In other respects, 2510 and 2510-AT basically have the same functions.

Main features:

• 50W TEC controller with DC measurement function
• Provide fully digital PID control
• Temperature control during laser diode module testing
• Wide temperature setting (-50℃ to +225℃), high resolution setting (±0.001℃), good stability (±0.005℃)
• Support a variety of temperature sensor inputs-thermistor, RTD and IC sensor
• Maintain constant temperature, current, voltage and sensor impedance
• AC ohm measurement method to detect mechanical damage of TEC
• Measure and display TEC parameters during temperature control
• Four-wire open/short continuity detection function for thermal feedback elements
• IEEE-488 and RS-232 interface
• Compact half-rack design
