Install with
python -m pip install cryocon-22c-controller
A CryoconController is a SCPI instrument and uses the easy-scpi package for means of communication. Thus, all the methods and properties of an easy_scpi.Instrument can be called.
Channels can be referenced either by their given name or their letter. All commands generate a response from the controller, so only queries are performed to keep command and response synched.
CryoconController( port, timeout, baud, backend, **resource_params ): Creates a new CryoconController instance.
max_temperatrue( loop ): Returns the maximum set point temperature of the given loop.
channel_max_temperatrue( loop ): Returns the maximum set point temperature of the loop controlling the given channel.
temperature( channel ): Returns the current temperature of the given channel
get_channel_loop( channel ): Returns the loop controlled by the given channel.
get_range( loop ): Gets the output range for the loop. Values are [ 'hi', 'mid', 'low' ].
set_range( loop, range ): Sets the ouput range for the loop. Range values are [ 'hi', 'mid', 'low' ].
get_ouput( loop ): Gets the power output of the loop as a fraction of the full range.
set_point( channel ): Returns the set point of the given channel.
set_temperature( channel, temperature ): Sets the set point of the controlling loop of the given channel.
lock( lock ): Locks or unlocks the front key pad.
enable(): Engages the temperature controller.
disable(): Stops the tempreature controller.
auto_adjust_range( low_threshold, high_threshold, channles ): Automatically adjusts the power range.
channels: A dictionary of aliases of the channels.
channel_names: A dictionary of given name of the channels.
loops: A dictionary of loop:input source pairs.
max_temps: A dictionary of maximum set point temperatures for each loop.
units: A dictionary of units for each channel.
enabled: Returns whether the temperature controller is currently engaged.
