– Compatibility & Integration
This laser module installs in the bottom slot of the Keysight 8164B Lightwave Measurement System Mainframe. Control is established through 81600B laser programming commands and the N7700A Photonic Application Suite. The mainframe remote interlock connector provides automatic safety interlock functionality. External voltage applied to any BNC connector must not exceed ±6 V absolute maximum.
