MFC

Aera MFC

class nupylab.instruments.mfc.aera_mfc.AeraMFC(port: str, addresses: int | Sequence[int], mfc_classes: AeraChannel | Sequence[AeraChannel], data_label: str | Sequence[str], name: str = 'Aera MFC')

Bases: NupylabInstrument

AeraMFC instrument class. Abstracts Aera MFC driver for NUPyLab procedures.

data_label: labels for DataTuples.

name: name of instrument.

lock: thread lock for preventing simultaneous calls to instrument.

aera: AeraMFC driver class with channels for all connected MFCs.

Initialize Aera data labels, name, and connection parameters.

Parameters:

port – string name of port, e.g. ASRL1::INSTR.
addresses – MFC addresses.
mfc_classes – MFC channel classes to add to AeraMFC.
data_label – labels for DataTuples. get_data() returns flow rate for each channel, and corresponding labels should match entries in DATA_COLUMNS of calling procedure class.
name – name of instrument.

Raises:

ValueError if lengths of addresses, mfc_classes, and data_label –
do not match. –

connect() → None: Connect to Aera MFCs.

get_data() → List[DataTuple]

Read flow for each MFC channel.

Returns:: DataTuples with flow for each channel.

set_parameters(setpoints: Sequence[float]) → None

Set Aera flow setpoints.

Parameters:: setpoints – MFC channel setpoints.
Raises:: ValueError if lengths of setpoints and data_label do not match. –

shutdown() → None: Shutdown Aera MFC gas flow and close serial connection.

start() → None

Convert setpoints from sccm to % and set flow.

Raises:: NupylabError if start method is called before set_parameters. –

stop_measurement() → None: Stop Aera MFC measurement. Not implemented.

ROD-4

class nupylab.instruments.mfc.rod4.ROD4(port: str, data_label: Sequence[str], name: str = 'ROD-4')

Bases: NupylabInstrument

ROD-4(A) instrument class. Abstracts ROD-4 driver for NUPyLab procedures.

data_label: labels for DataTuples.

name: name of instrument.

lock: thread lock for preventing simultaneous calls to instrument.

rod4: ROD4 driver class.

Initialize ROD-4 data labels, name, and connection parameters.
