a. Phase error and frequency error specifications apply when the Burst Sync is set to Training Sequence.
b. This term includes an error due to the software algorithm. The accuracy specification applies when
RMS phase error is less than 1°.
c. tfa = transmitter frequency
× frequency reference accuracy
d. The accuracy specification applies when the Burst Sync is set to Training Sequence, and Trigger is set
to External Trigger.
