Precision Temperature Control for TECs
The 2510 and 2510-AT TEC SourceMeter SMU instruments ensure tight temperature control for laser diode modules during test by controlling the operation of a laser diode module’s Thermo-Electric Cooler (TEC.) The 2510-AT offers an autotuning capability with which P, I, and D (proportional, integral, and derivative) values for closed loop temperature control are determined using a modified Zeigler-Nichols algorithm, eliminating the need to determine optimal values for these coefficients experimentally.
