Bug in multi-qubit pulse generator driver #80

Closed xionghn13 closed 6 years ago

xionghn13 commented 6 years ago

I want to set the Sequence in the Measurement Editor by double click that item, but when I try to set a new value for it, there is an error as follows:

12:55:17,329: An error occurred when sending a value to an instrument.

Instrument name: Simon's Multi-Qubit Pulse Generator (Simon's Multi-Qubit Pulse Generator) Address:
Quantity: Sequence Value: Pulse train

Error message: 2

Unfiltered error message: Traceback (most recent call last): File "BaseDriver.py", line 458, in processOperation File "BaseDriver.py", line 491, in performOperation File "BaseDriver.py", line 756, in _performSetValue File "E:\GitHubRepositories\labber-drivers\MultiQubit_PulseGenerator\MultiQubit_PulseGenerator.py", line 45, in performSetValue new_type = SEQUENCES[value] KeyError: 2

Do you know what's going on?

    if quant.name == 'Sequence':
        value = quant.getValue() 
        # create new sequence if sequence type changed
        new_type = SEQUENCES[value]

it seems that adding this line can solve this problem.

There is a bug in Labber's handling of setting combo-box values from the "Set Value"-dialog, will be fixed in the next release

Thanks for drawing our attention to the issue
