property data_complex

Get the complex s-parameter measurements from the last scan. This function is blocking until it is completed.

Parameters:

timeout – Optional value in seconds to wait until a timeout occurs. (default: 10)

Raises:

TimeoutError – If the VNA fails to complete the sweep before timeout occurs.

Returns:

An array of s-parameters for the measurement_parameter.

Return type:

numpy.ndarray

emit_beep()

Make the VNA emit a beep

property frequencies

Get a list of frequencies from the last scan.

Returns:

An array of frequencies sized by number of points in sweep)

Return type:

numpy.ndarray

property fw

Get the firmware of the instrument.

property id: Any

Get the identification of the instrument (list of strings)

property manu

property model

Get the model of the instrument.

property options: Any

Get the installed options for the instrument

property output_enabled: Any

Control RF Output State (boolean)

property power: Any

Control the output RF power of the instrument’s active port. (float).(dynamic)

reset()

Reset the instrument. May cause RF Output power to be enabled!

scan(timeout=10)

Initiates a scan with the number of averages specified and blocks until the operation is complete.

Parameters:

timeout – Optional value in seconds to add to the sweep time before timeout occurs. (default: 10)

Raises:

TimeoutError – If the VNA fails to complete the sweep before timeout occurs.

Returns:

None.
