HuberCC508

class icicle.hubercc508.HuberCC508(*args, **kwargs)

Bases: Instrument

__init__(resource='/dev/ttyACM0', mode='serial', timeout=2.5, baud=9600, sim=False)

Parameters:: resource – Resource address. See VISA docs for more info.

BAUD_RATE = 9600

MEASURE_TYPES = {'SPEED': 'Pump Speed (RPM)', 'TEMPERATURE': 'Bath Temperature (degC)'}: Measurement types for this instrument.

MODE = 'serial'

class MeasureChannel(instrument, channel, measure_type, unit='')

Bases: MeasureChannel

MeasureChannel implementation for Huber CC508.

property status

Returns:: Status Byte value.

property value

Performs measurement and returns value.

Returns:: measured value.
Return type:: float

OUTPUTS = 1

SETTINGS = {'SPEED': {'QUERY': 38}, 'SPEED_SETPOINT': {'QUERY': 72, 'SET': 72, 'verifier': <function is_numeric.<locals>._is_numeric>}, 'STATE': {'QUERY': 20, 'SET': 20, 'verifier': <function truthy.<locals>._truthy>}, 'TEMPERATURE': {'QUERY': 1, 'parser': <function HuberCC508.<lambda>>, 'unit': 'C'}, 'TEMPERATURE_SETPOINT': {'QUERY': 0, 'SET': 0, 'parser': <function HuberCC508.<lambda>>, 'unit': 'C', 'verifier': <function is_numeric.<locals>._is_numeric>}}

SET_REQUIRES_READBACK = False

SMALL_DELAY = 0.05: Small delay between subsequent commands (s).

TIMEOUT = 2.5

class TemperatureChannel(instrument, channel, measure_temperature, measure_speed)

Bases: TemperatureChannel

TemperatureChannel implementation for Huber CC508.

property speed

Returns:: currently set speed current.
Return type:: float

property state

Returns:: whether this power channel is on or off (True/False).
Return type:: bool

property status

Returns:: Measurement Status Register value.

property temperature

Returns:: currently set channel temperature.
Return type:: float

query(setting)

Query setting on instrument.

Parameters:

setting – key in class dictionary SETTINGS.
no_lock – override acquire_lock (e.g. if lock already taken by function that query-call is nested within).
attempts – how many retries to give query command.

Returns:

Data returned by device for given query.

set(setting, value, check_readback_only=False)

Set setting on instrument to value, and read-back using equivalent query().

Parameters:

setting – key in class dictionary SETTINGS.
value – target value for setting.
check_readback_only – how to only check readback value if SET_REQUIRES_READBACK is set, and not perform back-query. If ‘same’, checks that readback gives same command as was sent.
no_lock – override acquire_lock (e.g. if lock already taken by function that set-call is nested within).
attempts – how many retries to give set command.

Returns:

Read-back value if query() available, else whether number of bytes written during set() meets expectation

validate_channel(channel, raise_exception=True)

Check if a power channel exists on this device. Only successful if channel == 1.

Parameters:: channel – Channel number to validate as an input
