LD, TEC, PD, and EA can each be independently controlled with 4 channels, for a total of 16 channels of output!
The "LCD-7400C" is a 4-channel digital LD controller that can independently control up to 4 LD modules and measure with high precision. Additionally, it can perform sweeps of the LD current, PD reverse bias voltage, or EA voltage for each channel in arbitrary step widths in conjunction with external measuring devices, and it is capable of saving the measured current and voltage values of each terminal in its built-in memory. It is also equipped with GPIB and RS-232C interfaces, allowing for remote commands to monitor various settings and measurement values, as well as to acquire sweep data. 【Features】 ■ Independent control of a total of 16 channels of output ■ High-precision measurement of current and voltage at each terminal ■ Flexible remote control ■ Fast measurement ■ Compact space-saving design *For more details, please refer to the PDF documentation or feel free to contact us.
