ILX Lighwave LDP3811

class pymeasure.instruments.ilxlightwave.LDP3811(adapter, name='ILX Lightwave LDP 3811', includeSCPI=False, **kwargs)

Bases: Instrument

Represents the ILX Lightwave LDP3811 Pulsed Laser Diode Driver and provides a high-level interface for interacting with the instrument.

check_errors()

Read all errors from the instrument and log them.

Returns:: List of error entries.

check_get_errors()

Check for errors after having gotten a property and log them.

Called if check_get_errors=True is set for that property.

If you override this method, you may choose to raise an Exception for certain errors.

Returns:: list – List of error entries.

check_set_errors()

Check for errors after having set a property and log them.

Called if check_set_errors=True is set for that property.

If you override this method, you may choose to raise an Exception for certain errors.

Returns:: list – List of error entries.

clear()

Clears the instrument status byte

Return type:: None

property complete

Get the synchronization bit.

This property allows synchronization between a controller and a device. The Operation Complete query places an ASCII character 1 into the device’s Output Queue when all pending selected device operations have been finished.

property current: Any: Measure the current, in mA (float).

property current_limit_200: Any: Control the current limit for the 200mA range, in mA (float, strictly in range 0 to 200).

property current_limit_500: Any: Control the current limit for the 500mA range, in mA (float, strictly in range 0 to 500).

property current_range_500_enabled: Any: Control whether the 500mA output current range is enabled (bool). If False the 200mA output current range is selected.

property current_setpoint: Control the current setpoint, in mA (float, strictly in range 0 to (current_limit_500 if current_range_500_enabled else current_limit_200)).

property duty_cycle: Any: Measure the duty cycle (pulse width / pulse repetition interval), as a percentage (float).

property duty_cycle_setpoint: Control the duty cycle (pulse width / pulse repetition interval) as a percentage (float, strictly in range (100 * pulse_width / 6500) to 100).

property id: Get the identification of the instrument.

property mode: Any: Control the mode as an LDP3811Mode enum.

property next_error: Get the next error of the instrument (tuple of code and message).

property options: Get the device options installed.

property output_enabled: Any: Control whether the current output is enabled (bool).

property pulse_repetition_interval: Any: Measure the pulse repetition interval, in us (float).

property pulse_repetition_interval_setpoint: Control the pulse repetition interval, in us (float, strictly in range max(1, pulse_width) to 6500).

property pulse_width: Any: Measure the pulse width, in us (float).

property pulse_width_setpoint: Control the pulse width, in us (float strictly in range 0.1 to pulse_repetition_interval.

read(**kwargs)

Read up to (excluding) read_termination or the whole read buffer.

Return type:: str

read_binary_values(**kwargs): Read binary values from the device.

read_bytes(count, **kwargs)

Read a certain number of bytes from the instrument.

Parameters:

count (int) – Number of bytes to read. A value of -1 indicates to read the whole read buffer.
kwargs – Keyword arguments for the adapter.

Returns bytes:

Bytes response of the instrument (including termination).

Return type:

bytes

reset()

Resets the instrument.

Return type:: None

set_to_max_duty_cycle(): Set the duty cycle to the maximum valid value given the present mode, pulse width, and pulse repetition interval, and return the duty cycle.

set_to_min_duty_cycle(): Set the duty cycle to the minimum valid value given the present mode, pulse width, and pulse repetition interval, and return the duty cycle.

shutdown()

Brings the instrument to a safe and stable state

Return type:: None

property status: Get the status byte and Master Summary Status bit.

wait_for(query_delay=None)

Wait for some time. Used by ‘ask’ to wait before reading.

Parameters:: query_delay (Optional[float]) – Delay between writing and reading in seconds. None is default delay. (default: None)
Return type:: None

write(command, **kwargs)

Write a string command to the instrument appending write_termination.

Parameters:

command (str) – command string to be sent to the instrument
kwargs – Keyword arguments for the adapter.

Return type:

None

write_binary_values(command, values, *args, **kwargs)

Write binary values to the device.

Parameters:

command (str) – Command to send.
values (Sequence[Union[int, float]]) – The values to transmit.
**kwargs (*args,) – Further arguments to hand to the Adapter.

Return type:

None

write_bytes(content, **kwargs)

Write the bytes content to the instrument.

Return type:: None
