Specify which signal provides clock for sample conversions across channels
Note: You cannot use the legacy interface on 64–bit MATLAB®. See Session-Based Interface to acquire and generate data.
ExternalSampleClockSource specifies the pin whose signal is used as the channel clock for conversions on each channel. This property is in effect when the ClockSource property is set to ExternalSampleCtrl or ExternalSampleAndScanCtrl.
Data acquisition cards with simultaneous sample and hold ignore this property.
Read-only when running
PFI0 to PFI15
Use specified pin from PFI0 through PFI15.
RTSI0 to RTSI6
Use specified pin from RTSI0 through RTSI6.
