Phase locking of two lasers

[ZhimingShi]

Hello！When I run the case of two lasers locked, I always get the following error, why is this? I noticed the sentence mentioned at the beginning, how do I change the case code to make it work as expected?


Is there anyone who can help me I would be very grateful.

Hello,

To use this example, you need a different version of pyrpl which is now on a different github branch (https://github.com/lneuhaus/pyrpl/tree/modif_fpga_pfd). Note that there is a mistake and the name of the branch is actually "modif_fpga_pfd". You can use git to switch branch or download the code of the branch and replace the files on your computer.
Good luck !
