| =====Operating the FFC-CM===== | =====Operating the FFC-CM===== |
| This document provides basic instructions on how to operate the Vescent Photonics SVS Fiber Frequency Comb Module in conjunction with the Vescent SLICE-FPGA. It is important to note that the FFC-CM itself does not come with a built in GUI, and as such communication must be done through the [[link|Serial Command API]] or the [[link|FPGA Software]]. This document will walk through usage of the Serial Command interface including several basic commands, as well as using the FPGA Software to obtain and optimize your lock. | This document provides basic instructions on how to operate the Vescent Photonics SVS Fiber Frequency Comb Module in conjunction with the Vescent SLICE-FPGA.

| Open the WinPython folder and navigate to the site-packages directory: ''...\WPy64-3950\python-3.9.5.amd64\Lib\site-packages''. In a new window, also open the FPGA Software folder and locate the file "ok". Copy this file from FPGA Software into the site-packages directory of WinPython. Close the WinPython folder, and open a command line or terminal. Navigate to the ''...\FPGA Software\FPGA Software'' directory in the terminal and run the command ''pip install PyVISA-1.8-py2.py3-none-any.whl''. | Open the WinPython folder and navigate to the site-packages directory: ''...\WPy64-3950\python-3.9.5.amd64\Lib\site-packages''.

| | Finally, go back to the FPGA Software folder in your file explorer and run both "FrontPanelUSB-Win-x64-4.5.6", and "vcredist_x64". Each will open their own installer. Follow the instructions on both and click finish. When both are done installing, your computer should be configured to run the FPGA software. |
| =====Locking the SVS FFC Module===== | =====Locking the SVS FFC Module===== |
| Before locking, it may be beneficial to familiarize yourself with the full list of API commands for the SVS FFC Module, which can be found [[link|here]], as well as the front and rear panel connections, which can be found [[link|here]]. It is also important to note that, aside from those set in the FPGA software, all PID parameters come preset and should not need to be adjusted. | Before locking, it may be beneficial to familiarize yourself with the full list of API commands for the SVS FFC Module, which can be found [[ffc:cm:api-osc|here]], as well as the front and rear panel connections, which can be found in Figure 8. It is also important to note that, aside from those set in the FPGA software, all PID parameters come preset and should not need to be adjusted. |

| Now that the system is mode locked, switch the monitored output to SC Out and change your Spectrum Analyzer or OSA's window to span the 1-2 micron wavelength region. Verify that the supercontinuum of your system matches that shown in your CoC. An example supercontinuum can be seen in <imgref SC> | Now that the system is mode locked, turn on the EDFA/AMP pump diode and switch the monitored output to SC Out. Change your Spectrum Analyzer or OSA's window to span the 1-2 micron wavelength region and verify that the supercontinuum of your system matches that shown in your CoC. An example supercontinuum can be seen in <imgref SC> |
