CC1 Coincidence Counter

class instruments.qubitekk.CC1(filelike)

The CC1 is a hand-held coincidence counter.

It has two setting values, the dwell time and the coincidence window. The coincidence window determines the amount of time (in ns) that the two detections may be from each other and still be considered a coincidence. The dwell time is the amount of time that passes before the counter will send the clear signal.

class Channel(cc1, idx)

Class representing a channel on the Qubitekk CC1.

property count

Gets the counts of this channel.

Return type:

int

clear_counts()

Clears the current total counts on the counters.

property acknowledge

Gets/sets the acknowledge message state. If True, the CC1 will echo back every command sent, then print the response (either Unable to comply, Unknown command or the response to a query). If False, the CC1 will only print the response.

Units:

None

Type:

boolean

property channel

Gets a specific channel object. The desired channel is specified like one would access a list.

For instance, this would print the counts of the first channel:

>>> cc = ik.qubitekk.CC1.open_serial('COM8', 19200, timeout=1)
>>> print(cc.channel[0].count)

Return type:

CC1.Channel

property delay

Get/sets the delay value (in nanoseconds) on Channel 1.

When setting, N may be 0, 2, 4, 6, 8, 10, 12, or 14ns.

Return type:

Quantity

Returns:

the delay value

property dwell_time

Gets/sets the length of time before a clear signal is sent to the counters.

Units:

As specified (if a Quantity) or assumed to be of units seconds.

Type:

Quantity

property firmware

Gets the firmware version

Return type:

tuple`(Major:`int, Minor:int, Patch`int`)

property gate

Gets/sets the gate enable status

Type:

bool

property subtract

Gets/sets the subtract enable status

Type:

bool

property trigger_mode

Gets/sets the trigger mode setting for the CC1. This can be set to continuous or start/stop modes.

Type:

CC1.TriggerMode

property window

Gets/sets the length of the coincidence window between the two signals.

Units:

As specified (if a Quantity) or assumed to be of units nanoseconds.

Type:

Quantity

MC1 Motor Controller

class instruments.qubitekk.MC1(filelike)

The MC1 is a controller for the qubitekk motor controller. Used with a linear actuator to perform a HOM dip.

class MotorType(*values)

Enum for the motor types for the MC1

radio = 'Radio'

relay = 'Relay'

center()

Commands the motor to go to the center of its travel range

is_centering()

Query whether the motor is in its centering phase

Returns:

False if not centering, True if centering

Return type:

bool

move(new_position)

Move to a specified location. Position is unitless and is defined as the number of motor steps. It varies between motors.

Parameters:

new_position (Quantity) – the location

reset()

Sends the stage to the limit of one of its travel ranges

property controller

Get the motor controller type.

property direction

Get the internal direction variable, which is a function of how far the motor needs to go.

Type:

Quantity

Units:

milliseconds

property firmware

Gets the firmware version

Return type:

tuple`(Major:`int, Minor:int, Patch`int`)

property increment

Gets/sets the stepping increment value of the motor controller

Units:

As specified, or assumed to be of units milliseconds

Type:

Quantity

property inertia

Gets/Sets the amount of force required to overcome static inertia. Must

be between 0 and 100 milliseconds.

Type:

Quantity

Units:

milliseconds

property internal_position

Get the internal motor state position, which is equivalent to the total

number of milliseconds that voltage has been applied to the motor in the positive direction minus the number of milliseconds that voltage has been applied to the motor in the negative direction.

Type:

Quantity

Units:

milliseconds

property lower_limit

Gets/sets the stepping lower limit value of the motor controller

Units:

As specified, or assumed to be of units milliseconds

Type:

Quantity

property metric_position

Get the estimated motor position, in millimeters.

Type:

Quantity

Units:

millimeters

property move_timeout

Get the motor’s timeout value, which indicates the number of milliseconds before the motor can start moving again.

Type:

Quantity

Units:

milliseconds

property setting

Gets/sets the output port of the optical switch. 0 means input 1 is directed to output 1, and input 2 is directed to output 2. 1 means that input 1 is directed to output 2 and input 2 is directed to output 1.

Type:

int

property step_size

Gets/Sets the number of milliseconds per step. Must be between 1 and 100 milliseconds.

Type:

Quantity

Units:

milliseconds

property upper_limit

Gets/sets the stepping upper limit value of the motor controller

Units:

As specified, or assumed to be of units milliseconds

Type:

Quantity
