Use Valon 5007 to Set Clock Frequency to ROACH

If you're using a Valon 5007 Frequency Synthesizer to set the clock of your ROACH/ADCs, the easiest way to control it in a Linux machine is with this NRAO C++/Python interface. Just follow the instructions to install it and use it.

You can also use this script to quickly change the synthesizer parameters from terminal.

Be aware that the power levels specified by the NRAO interface not necessarily correspond to the output power of the synthesizer, so always check the real power with a power meter.
