High-precision measurement and control, common connection-free! Usable for testing and evaluating DC characteristics of various optical modulation modules such as VOA.
This product is a multi-channel compatible LD driver. It features 4-channel ATC/ACC/APC control for high-precision measurement control, with common connection free. There is also a high-precision type available that allows independent control of LD, TEC, EA, and PD. Furthermore, it can perform sweeps of LD current, PD reverse bias voltage, or EA voltage for each channel in arbitrary step widths in conjunction with external measuring instruments, and it is possible to save the measured current and voltage values of each terminal in the built-in memory. 【Features】 ■ 4-channel ATC/ACC/APC control ■ High-precision measurement control, common connection free ■ 4-channel LD current/EA voltage sweep ■ Collaboration with other measuring instruments via trigger signals ■ Space-saving (210(W)×125(H)×420(D)mm) *excluding protrusions *For more details, please download the PDF or feel free to contact us.
