check_errors()

Read all errors from the instrument.

Returns:

List of error entries.

get_error_message(error_code)

Return the error message for to the specified error code (str).

property options: Any

Get the installed SMUs (list of str).

Each list entry contains the module name and its revision, e.g. E5281B,0 An empty slot returns 0,0

class pymeasure.instruments.agilent.agilentE5270B.Display(parent, id, **kwargs)

Bases: Channel

A class representing the Agilent E5270B display.

property enabled: Any

Set whether the display is enabled during remote operation (bool).

property engineering_format_enabled: Any

Set whether the engineering data format or the scientific data format is used (bool).

Example:

  • True (engineering): +123.456mA

  • False (scientific): +1.234E-1A

Note

Executing reset() sets the data format to scientific.

property measurement_parameter: Any

property measurement_smu: Any

Set the measurement SMU for the data displayed on the LCD (int, strictly from 1 to 8).

property source_parameter1: Any

Set the parameter displayed in line 1 of the Source Data display area (str, strictly in set_point, compliance, voltage_range, current_range or error).

property source_parameter2: Any

Set the parameter displayed in line 2 of the Source Data display area (str, strictly in set_point, compliance, voltage_range, current_range or error).

property source_smu: Any

Set the source SMU for the data displayed on the LCD. (int, strictly from 1 to 8).

class pymeasure.instruments.agilent.agilentE5270B.SMUChannel(parent, id, **kwargs)

Bases: Channel
