class dodal.devices.current_amplifiers.CurrentAmp[source]#

Base class for current amplifier, it contains the minimal functionality a current amplifier needs:

gain_conversion_table#

The conversion table between current and gain setting.

Type:

Enum

Parameters:

  • gain_conversion_table (type[Enum])

  • name (str, default: '')

Methods

decrease_gain([value])

Decrease gain, decrement by 1 by default.

get_gain()

Get the current gain setting.

get_lowerlimit()

Get the lower limit of the current amplifier.

get_upperlimit()

Get the upper limit of the current amplifier.

increase_gain([value])

Increase gain, increment by 1 by default.

Attributes

abstract async increase_gain(value: int = 1) → None[source]#

Increase gain, increment by 1 by default.

Returns:

True if success.

Return type:

bool

Parameters:

value (int, default: 1)

abstract async decrease_gain(value: int = 1) → None[source]#

Decrease gain, decrement by 1 by default.

Returns:

True if success.

Return type:

bool

Parameters:

value (int, default: 1)

abstract async get_gain() → Enum[source]#

Get the current gain setting.

Returns:

The member name of the current gain setting in gain_conversion_table.

Return type:

Enum

abstract async get_upperlimit() → float[source]#

Get the upper limit of the current amplifier.

Return type:

float

abstract async get_lowerlimit() → float[source]#
