Inputs/Outputs
reference (input) clock source
—
input clock source specifies the input source for the PLL reference clock (such as the 1-20 MHz clock on SMC-based devices) to which the digitizer is phase-locked for all digitizers. Refer to the Reference (Input) Clock Source property for defined values. Default Value: None
instrument handle
—
instrument handle identifies a particular instrument session.
clock sync pulse source
—
clock sync pulse source specifies the line on which the sample clock or the one-time sync pulse is sent or received. Default Value: RTSI 0 Refer to the Clock Sync Pulse Source property for defined values.
master enabled
—
master enabled specifies whether the device is a master or a slave; the master device is typically the originator of the trigger signal and clock sync pulse. For a standalone device, set this parameter to FALSE. Default Value: FALSE
error in
—
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
output clock source
—
output clock source specifies the output source for the PLL reference clock to which the sample clock of another digitizer can be phase-locked. Refer to the Output Clock Source property for more information. Default Value: None
instrument handle out
—
instrument handle out has the same value as the instrument handle.
error out
—
error out contains error information. This output provides standard error out functionality. |
