QCoDeS example with Valon 5015¶

The Valon 5015 frequency synthesizer uses multiple phase lock loops to provide exceptionally low phase noise over the 10MHz to 15GHz range. The multiple loop technique also greatly reduced spurs while providing high resolution tuning precision. Calibrated output power may be accurately set from +13dBm down to -30dBm in 0.1dB steps.

Be sure to specify the correct IP address in the constructor. If the driver cannot find the device, a VisaIOError is raised.

[2]:

ip = "192.168.0.3"
valon = Valon5015(name="Valon", address=f"TCPIP0::{ip}::23::SOCKET")

Get status of the device:

[3]:

status = valon.status()
print(status)
