How to use the nitclk._attributes.AttributeViString function in nitclk

'''

    Specifies the external sync pulse source for the Sync Pulse Sender.  You can use this source to synchronize  the Sync Pulse Sender with an external non-TClk source.
    Values
    Empty string. Empty string is a valid value, indicating that the signal is  not exported.
