Hi, I am using Mirny frequency synthesiser. I am trying to use Almazny HF mezzanine, but I am having some issue.
I am looking at the
artiq.coredevice.mirny.Almazny from M-lab, and I cannot find a way to set the frequency of the signal. Are they fixed frequency?
Here is the code,
from artiq.experiment import *
import numpy as np
class HFgen(EnvExperiment):
def build(self):
self.setattr_device("core")
self.setattr_device("mirny0_almazny")
@kernel
def run(self):
self.core.reset()
delay(10*ms)
self.mirny0_almazny.init()
self.mirny0_almazny.att_to_mu(5.0)
delay(100*ms)
and here is the device list related to mirny
