Specify which signal starts series of conversions across channels
Note: You cannot use the legacy interface on 64–bit MATLAB®. See Session-Based Interface to acquire and generate data.
ExternalScanClockSource specifies the pin whose signal is used as the scan clock to initiate conversions across a group of channels. This property is in effect when the ClockSource property is set to ExternalScanCtrl or ExternalSampleAndScanCtrl.
