Helper code to control Windfreak's SynthHD RF generator.
pip install qt3rfsynthcontrol
import qt3rfsynthcontrol
qt3rfsynthcontrol.discover_devices()Will return a list of ports and information about devices connected to those ports. For example
[['COM3',
'Intel(R) Active Management Technology - SOL (COM3)',
'PCI\\VEN_8086&DEV_43E3&SUBSYS_0A541028&REV_11\\3&11583659&1&B3'],
['COM5',
'USB Serial Device (COM5)',
'USB VID:PID=0483:A3E5 SER=206A36705430 LOCATION=1-2:x.0'],
['COM6',
'USB Serial Device (COM6)',
'USB VID:PID=04D8:000A SER= LOCATION=1-8:x.0'],
['COM7',
'USB Serial Device (COM7)',
'USB VID:PID=239A:8014 SER=3B0D07C25831555020312E341A3214FF LOCATION=1-6:x.0']]It is certainly not obvious to which USB port the Windfreak is connected. However, using the Windows Task Manager, as well as trial and error, should eventually reveal the correct serial port to use.

can obtain it from the property SynthHD. Usage of
windfreak-python is documented here.
windfreak_synthhd = rf_synth.SynthHD()
print(windfreak_synthhd[0].power)
print(windfreak_synthhd[0].frequency)The documentation is a little sparse, however. The full set of commands are found in
It can take a little effort to match the python API with the description in the manual as
some of the windfreak-python API functions do not exactly match the function name in the manual.
For example sweep_single in windfreak-python is called sweep_run or run_sweep
in the programming manual.
