22.22 Jitter analysis and clock data recovery
This chaptes decribes the remote commands of jitter option R&S RTP-K12 /K133 and
CDR option R&S RTP-K140/K141.
Some of the commands in the following chapter are asynchronous. An overlapping or
asynchronous command does not automatically finish executing before the next com-
mand starts executing. If overlapping commands must be executed in a defined order,
e.g. to avoid wrong measurement results, they must be serviced sequentially.
To prevent an overlapping execution of commands, one of the commands *OPC,
*OPC? or *WAI can be used after the command or a command set.
