Use the niUSRP Synchronization VIs to synchronize timing in applications for USRP devices.

niUSRP Configure Trigger VI
Configures the trigger generated by the onboard device timer. The trigger specifies the time to acquire or generate the first sample.
niUSRP Set Time VI
Sets the time value of the onboard device timer.
niUSRP Disable Start Trigger VI
Disables the Start Trigger. When the Start Trigger is disabled, acquisitions and generations begin immediately when data is available.
niUSRP Get Time VI
Returns the time value of the onboard device timer.
niUSRP Wait For Lock VI
Configures the device to wait for the GPS to lock. GPSDO may take up to 10 minutes to lock to a satellite the first time.
niUSRP Export Signal VI
Creates a route to export the specified signal to the specified output terminal. Valid mapping is one-to-one such that Reference Frequency maps to REF OUT, Timebase Clock maps to PPS TRIG OUT, and LO maps to LO OUT.
niUSRP Set Command Time VI
Tells the device to execute the next hardware configuration setting at the specified timestamp. This should only be used after niUSRP Initiate VI is called on the session.
niUSRP Clear Command Time VI
Clears command times, causing future control commands to take effect immediately. Previous control commands will still occur at their associated command times.
