NI-SCOPE (English | Japanese)

Configures the properties for synchronizing the digitizer to an external clock or sending the digitizer's clock output to be used as a synchronizing clock for other devices.

Note  Some features are not supported by all digitizers. Refer to Features Supported by Device for more information.

instrument handle identifies a particular instrument session.

clock sync pulse source specifies the line on which the sample clock is sent or received for the NI 5102; for the NI 5112/5620/5621/5911, specifies the line on which the one-time sync pulse is sent or received. This line should be the same for all devices to be synchronized.

Default Value: RTSI 0

Refer to the Clock Sync Pulse Source property for defined values.

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 stand-alone device, set this parameter to FALSE.

Refer to the Master Enable property for more information.

Default Value: FALSE

input clock source specifies the input source for the PLL reference clock (the 1-20 MHz clock on SMC-based devices, the 10 MHz clock for the NI 5112/5620/5621/5911) to which the digitizer is phase-locked for all digitizers except the NI 5102; for the NI 5102, this is the source of the board clock. Refer to the Reference (Input) Clock Source property for defined values.

Default Value: None

output clock source specifies the output source for the PLL reference clock (20 MHz in the NI 5102) to which another digitizer's sample clock can be phased-locked. Set parameter to RTSI Clock to specify the NI 5102 as a master; refer to the Output Clock Source property for more information.

Default Value: None
