labscript.outputs.StaticAnalogQuantity

class StaticAnalogQuantity(*args, **kwargs)

Bases: Output

Base class for StaticAnalogOut.

It can also be used internally by other more complex output types.

__init__(*args, **kwargs)

Instatiantes the static analog quantity.

Defines an internal tracking variable of the static output value and calls Output.__init__().

Parameters:

• *args – Passed to Output.__init__().

• **kwargs – Passed to Output.__init__().

Methods

__init__(*args, **kwargs)	Instatiantes the static analog quantity.
add_device(device)	Adds a child device to this device.
add_instruction(time, instruction[, units])	Adds a hardware instruction to the device instruction list.
apply_calibration(value, units)	Apply the calibration defined by the unit conversion class, if present.
constant(value[, units])	Set the static output value of the output.
do_checks(trigger_times)	Basic error checking to ensure the user's instructions make sense.
expand_timeseries(*args, **kwargs)	Defines the raw_output attribute.
generate_code(hdf5_file)	Generate hardware instructions for device and children, then save to h5 file.
get_all_children()	Get all children devices for this device.
get_all_outputs()	Get all children devices that are outputs.
get_change_times()	Enforces no change times.
get_properties([location])	Get all properties in location.
get_property(name[, location])	Method to get a property of this device already set using Device.set_property().
get_ramp_times()	If this is being called, then it means the parent Pseuedoclock has asked for a list of the output ramp start and stop times.
init_device_group(hdf5_file)	Creates the device group in the shot file.
instruction_to_string(instruction)	Gets a human readable description of an instruction.
make_timeseries(change_times)	Since output is static, does nothing.
offset_instructions_from_trigger(trigger_times)	Subtracts self.trigger_delay from all instructions at or after each trigger_time.
quantise_to_pseudoclock(times)	Quantises times to the resolution of the controlling pseudoclock.
set_properties(properties_dict, property_names)	Add one or a bunch of properties packed into properties_dict
set_property(name, value[, location, overwrite])	Method to set a property for this device.

Attributes

allowed_children	Defines types of devices that are allowed to be children of this device.
allowed_states
clock_limit	Returns the parent clock line's clock limit.
default_value	Value of output if no constant value is commanded.
description	Brief description of the device.
parent_clock_line	Stores the clocking clockline, which may be itself.
pseudoclock_device	Stores the clocking pseudoclock, which may be itself.
scale_factor
static_value	The value of the static output.
t0	The earliest time output can be commanded from this device at the start of the experiment.
trigger_delay	The earliest time output can be commanded from this device after a trigger.
wait_delay	The earliest time output can be commanded from this device after a wait.

constant(value, units=None)

Set the static output value of the output.

Parameters:

• value (float) – Value to set the output to.

• units – Units, defined by the unit conversion class, the value is in.

Raises:

LabscriptError – If static output has already been set to another value or the value lies outside the output limits.

default_value = 0.0

Value of output if no constant value is commanded.

Type:

float

description = 'static analog quantity'

Brief description of the device.

expand_timeseries(*args, **kwargs)

Defines the raw_output attribute.

get_change_times()

Enforces no change times.

Returns:

An empty list, as expected by the parent pseudoclock.

Return type:

list

make_timeseries(change_times)

Since output is static, does nothing.

property static_value

The value of the static output.

Type:

float
