class lantz.drivers.newport.PowerMeter1830c(resource_name, name=None, **kwargs)[source]¶

Bases: lantz.messagebased.MessageBasedDriver

Newport 1830c Power Meter

Parameters:	resource_name (str) – The resource name kwargs – keyword arguments passed to the resource during initialization.
Params name:	easy to remember identifier given to the instance for logging purposes.

autocalibration_async(*args, **kwargs)¶: (Async) Autocalibration of the power meter. This procedure disconnects the input signal. It should be performed at least 60 minutes after warm-up.

store_reference_async(*args, **kwargs)¶: (Async) Sets the current input signal power level as the power reference level. Each time the S command is sent, the current input signal becomes the new reference level.

DEFAULTS = {'ASRL': {'baud_rate': 9600, 'parity': <Parity.none: 0>, 'read_termination': '\n', 'stop_bits': <StopBits.one: 10>, 'write_termination': '\n', 'bytesize': 8, 'timeout': 2000, 'encoding': 'ascii'}}¶

DEFAULTS_changed¶

attenuator¶

Attenuator.: 1: Attenuator present 0: Attenuator not present

Values:	{False: 0, True: 1}

attenuator_changed¶

autocalibration = functools.partial(<bound method Action.call of <lantz.action.Action object at 0x7fe1f4b7b208>>, None)¶

autocalibration_changed¶

beeper¶

Checks whether the audio output is on or off.

Values:	{False: 0, True: 1}

beeper_changed¶

data¶

data_changed¶

echo¶

Returns echo mode. Only applied to RS232 communication

Values:	{False: 0, True: 1}

echo_changed¶

filter¶

How many measurements are averaged for the displayed reading.: slow: 16 measurements medium: 4 measurements fast: 1 measurement.

Values:	{‘Fast’: 3, ‘Slow’: 1, ‘Medium’: 2}

filter_changed¶

go¶

Enable or disable the power meter from taking new measurements.

Values:	{False: 0, True: 1}

go_changed¶

keypad¶

Keypad/Display backlight intensity levels.

Values:	{‘High’: 2, ‘Medium’: 1, ‘Off’: 0}

keypad_changed¶

lockout¶

Enable/Disable the lockout. When the lockout is enabled, any front panel key presses would have no effect on system operation.

Values:	{False: 0, True: 1}

lockout_changed¶

range¶

Set the signal range for the input signal.: 0 means auto setting the range. 1 is the lowest signal range and 8 the highest.

Values:	{0, 1, 2, 3, 4, 5, 6, 7, 8}

range_changed¶

store_reference = functools.partial(<bound method Action.call of <lantz.action.Action object at 0x7fe1f4b7b518>>, None)¶

store_reference_changed¶

units¶

Sets and gets the units of the measurements.

Values:	{‘dB’: 2, ‘REL’: 4, ‘dBm’: 3, ‘Watts’: 1}

units_changed¶

wavelength¶

Sets and gets the wavelength of the input signal.

Limits:	(1, 10000, 1)

wavelength_changed¶

zero¶

Turn the zero function on/off. Zero function is used for subtracting any background power levels in future measurements.

Values:	{False: 0, True: 1}

zero_changed¶
