Synchronize mixers

When setting up digital mixers with hardware.configure_mixer the parameter sync indicates when to start the mixers. When we pass sync=False the mixer is ‘armed’ and the numerically controlled oscillator (NCO) connected to the LO port of the mixer is ready to be started. When we pass sync=True that mixer’s NCO is ‘armed’ and all the already armed NCOs are started at the same time. The default value of the sync parameter is True.

In the following example, the NCO that is at 5 GHz starts first. After that, mixers with NCO frequencies 6 and 7 GHz start together.

pls.hardware.configure_mixer(freq=5e9, in_ports=1, out_ports=1)

pls.hardware.configure_mixer(freq=6e9, in_ports=2, out_ports=2, sync=False)
pls.hardware.configure_mixer(freq=7e9, out_ports=3, sync=True)
