External Sample Clock Timebase
The Sample clock timebase has an external source that derives device
clocking by directly driving the DAC and all waveform generation
operations on the device.
You can set the Sample clock timebase source by calling the Sample Clock
Timebase Source property or the
NIFGEN_ATTR_SAMPLE_CLOCK_TIMEBASE_SOURCE
attribute. You can
set the Sample clock timebase rate with the Sample Clock Timebase Rate
property or the
NIFGEN_ATTR_SAMPLE_CLOCK_TIMEBASE_RATE
attribute.
You can export the Sample clock timebase to a terminal configured by the
Sample Clock Timebase Export Output Terminal property or the
NIFGEN_ATTR_EXPORTED_SAMPLE_CLOCK_TIMEBASE_OUTPUT_
TERMINAL
attribute.
Note
Refer to the device specifications for the allowable voltages, signal types, and
clocks that you can use for an external Sample clock timebase.
