Aim-TTi Electronic Loads

class pymeasure.instruments.aimtti.ld400p.LD400P(adapter, name='LD400', **kwargs)

Bases: SCPIMixin, Instrument

Interface for the LD400P electronic DC load from Aim-TTi.

Note: the LD400 edition doesn’t have digital interfacing, only the LD400P does.

The interface is described by the LD400[P] manual.

The class SCPIMixin is inherited, however the commands options, next_error` and check_errors do not work for this device.

check_errors()

Not available.

property current

Get the measured load current (float).

property input_enabled

Control the input state of the digital load, can be True (on) or False (off).

property level_a

Control the A level of the current control mode (float).

property level_b

Control the B level of the current control mode (float).

property level_select

Control the selected level of the digital load. Can be one of: ("A", "B", "T", "V", "E"), corresponding to (respectively) Level A, Level B, Transient, Ext Voltage and Ext TTL (string).

property mode

Control the mode of the digital load. Can be one of: ("C", "P", "R", "G", "V"), corresponding to (respectively) constant current, power, resistance, conductance, or voltage (string).

property next_error

Get next error - Not available.

property options

Get options - Not available.

classmethod remove_unit_suffix(msg: str) → str

Remove known unit suffixes from a msg.

The units of some replies depend on the mode of the device, hence all known units are removed.

property voltage

Get the measured source input voltage (float).
