3、 Advantages of keithleysourcemeter optical instrument:
To prevent the temperature change may cause the main output wavelength of laser diode to change, resulting in signal overlap and crosstalk problems.
Higher test speed and wider temperature setting range than other low power solutions.
It provides higher temperature stability and can be easily upgraded through simple firmware changes.
The combination of P, I and D coefficients can be determined without repeated experiments.
It can meet the test requirements of most cooling optical components and subassemblies.
Suitable for all kinds of temperature sensors commonly used in laser diode module.
Verify the integrity of Tec devices.
Eliminate lead resistance measurement error, reduce the possibility of false fault or equipment damage.
