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.
-
CC1.
clear_counts
()¶ Clears the current total counts on the counters.
-
CC1.
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
-
CC1.
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

CC1.
delay
¶ Get/sets the delay value (in nanoseconds) on Channel 1.
When setting,
N
may be0, 2, 4, 6, 8, 10, 12, or 14ns
.Return type: quantities.ns Returns: the delay value

CC1.
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
-
CC1.
trigger_mode
¶ Gets/sets the trigger mode setting for the CC1. This can be set to
continuous
orstart/stop
modes.Type: CC1.TriggerMode
-
CC1.
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
