Hi,

Thank you for your reply. 

My schematic is a closed loop, it means that the time delay (usually caused by fiber's length) much affects on the signal performance. That's why I dont understand the role of time delay (DLY) component in library. 

About linewidth, I just want to control the performance of Laser source to check performance of RF signal (for example phase noise). I need frequency resolution of RFSA about 1000 Hz. 

about sending the file, how can i send my file to you via this forum? here there are only image and insert link place.

Thank you.
