1
class stanza.base.mixins.InstrumentChannelMixin

Mixin class that provides the default InstrumentChannel implementation.

1
add_channel(
2
    channel_name_or_channel: str | stanza.base.channels.InstrumentChannel | None,
3
    channel: stanza.base.channels.InstrumentChannel | None = None
4
) -> None

Add a channel to the instrument.

Can be called as:

• add_channel(channel) - uses channel.name as key
• add_channel(channel_name, channel) - uses provided name as key

1
get_channel(channel_name: str) -> stanza.base.channels.InstrumentChannel

Get a channel by name.

1
remove_channel(channel_name: str) -> None

Remove a channel from the instrument.

1
class stanza.base.mixins.ControlInstrumentMixin

Bases: stanza.base.mixins.InstrumentChannelMixin

Mixin class that provides the default ControlInstrument implementation using channel parameters.

1
set_voltage(
2
    channel_name: str, voltage: float
3
) -> None

Set voltage on a specific channel using parameter system.

1
get_voltage(channel_name: str) -> float

Get current voltage on a specific channel using parameter system.

1
get_slew_rate(channel_name: str) -> float

Get current slew rate on a specific channel using parameter system.

1
set_slew_rate(
2
    channel_name: str, slew_rate: float
3
) -> None

Set slew rate on a specific channel using parameter system.

1
class stanza.base.mixins.MeasurementInstrumentMixin

Bases: stanza.base.mixins.InstrumentChannelMixin

Mixin class that provides default MeasurementInstrument implementations.

1
prepare_measurement_context() -> collections.abc.Generator[None, None, None]

Context manager that handles preparation, avoiding nested calls.

1
prepare_measurement() -> None

Override in subclasses for actual preparation logic.

1
teardown_measurement() -> None

Optional override in subclasses for actual teardown logic.

1
measure(channel_name: str) -> float

Default measurement that reads the ‘current’ parameter from the first channel.

Subclasses are expected to expose channels via get_channel(int) and a ‘current’ Parameter on each channel whose getter performs the measurement.
