qcodes_contrib_drivers.drivers.CopperMountain.M5180 module

class qcodes_contrib_drivers.drivers.CopperMountain.M5180.FrequencySweepMagPhase(name: str, start: float, stop: float, npts: int, instrument: M5180, **kwargs: Any)

Bases: MultiParameter

Sweep that returns magnitude and phase.

__init__(name: str, start: float, stop: float, npts: int, instrument: M5180, **kwargs: Any) → None

Linear frequency sweep that returns magnitude and phase for a single trace.

Parameters:

• name (str) – Name of the linear frequency sweep

• start (float) – Start frequency of linear sweep

• stop (float) – Stop frequency of linear sweep

• npts (int) – Number of points of linear sweep

• instrument – Instrument to which sweep is bound to.

get_raw() → Tuple[Any, Any]

Gets data from instrument

Returns:

magnitude, phase

Return type:

Tuple[ParamRawDataType, …]

set_sweep(start: float, stop: float, npts: int) → None

Updates the setpoints and shapes based on start, stop and npts.

Parameters:

• start (float) – start frequency

• stop (float) – stop frequency

• npts (int) – number of points

class qcodes_contrib_drivers.drivers.CopperMountain.M5180.M5180(*args: Any, **kwargs: Any)

Bases: VisaInstrument

This is the QCoDeS python driver for the VNA M5180 from Copper Mountain

__init__(name: str, address: str, terminator: str = '\n', timeout: int = 100000, **kwargs)

QCoDeS driver for the VNA M5180 from Copper Mountain. This driver only uses one channel.

Parameters:

• name (str) – Name of the instrument.

• address (str) – Address of the instrument.

• terminator (str) – Terminator character of the string reply. Optional, default "\n"

• timeout (int) – VISA timeout is set purposely to a long time to allow long spectrum measurement. Optional, default 100000

get_s() → Tuple[ndarray, ndarray, ndarray, ndarray, ndarray, ndarray, ndarray, ndarray, ndarray]

Return all S parameters as magnitude in dB and phase in rad.

Returns:

frequency [GHz], s11 magnitude [dB], s11 phase [rad], s12 magnitude [dB], s12 phase [rad], s21 magnitude [dB], s21 phase [rad], s22 magnitude [dB], s22 phase [rad]

Return type:

Tuple[np.ndarray]

reset_averages() → None

Resets average count to 0

update_lin_traces() → None

Updates start, stop and npts of all trace parameters so that the setpoints and shape are updated for the sweep.

class qcodes_contrib_drivers.drivers.CopperMountain.M5180.PointIQ(name: str, instrument: M5180, **kwargs: Any)

Bases: MultiParameter

Returns the average Sxx of a frequency sweep, in terms of I and Q. Work around for a CW mode where only one point is read. npts=2 and stop = start + 1 (in Hz) is required.

__init__(name: str, instrument: M5180, **kwargs: Any) → None

I and Q measurement of a single point at start frequency.

Parameters:

• name (str) – Name of point measurement

• instrument – Instrument to which parameter is bound to.

get_raw() → Tuple[Any, Any]

Gets data from instrument

Returns:

I, Q

Return type:

Tuple[ParamRawDataType, …]

class qcodes_contrib_drivers.drivers.CopperMountain.M5180.PointMagPhase(name: str, instrument: M5180, **kwargs: Any)

Bases: MultiParameter

Returns the average Sxx of a frequency sweep. Work around for a CW mode where only one point is read. npts=2 and stop = start + 1 (in Hz) is required.

__init__(name: str, instrument: M5180, **kwargs: Any) → None

Magnitude and phase measurement of a single point at start frequency.

Parameters:

• name (str) – Name of point measurement

• instrument – Instrument to which parameter is bound to.

get_raw() → Tuple[Any, Any]

Gets data from instrument

Returns:

magnitude, phase

Return type:

Tuple[ParamRawDataType, …]

exception qcodes_contrib_drivers.drivers.CopperMountain.S5048.TraceNotReady

Bases: Exception

class qcodes_contrib_drivers.drivers.CopperMountain.S5048.CMTS5048(*args: Any, **kwargs: Any)

Bases: VisaInstrument

This is the QCoDeS driver for the S5048 Network Analyzer

invalidate_trace(cmd: str, value: float | int | str) → None

Wrapper for set_cmds that make the trace not ready

reset() → None

Resets the instrument to factory default state

run_N_times(N: int) → None

Run N sweeps and then hold. We wait for a response before returning

run_continously() → None

Set the instrument in run continously mode

startup() → None

class qcodes_contrib_drivers.drivers.CopperMountain.S5048.CMTS5048Trace(name, instrument)

Bases: ArrayParameter

Class to hold a the trace from the S5048 network analyzer

get_raw()

Return the trace

prepare_trace()

Update setpoints, units and labels

qcodes_contrib_drivers.drivers.CopperMountain.S5048.CMTIntParser(value: str) → int
