Using Sequences
Usage:
• All L4400 Series Instruments
This section gives information on defining and executing a sequence,

which is a compiled series of SCPI commands stored in non- volatile
memory and identified by a user- defined name. Sequences can be used
in a variety of applications, such as creating a signal path from a
device- under- test to a measurement device or sequencing relays in a
specified order. You can also uses sequences in conjunction with other
operations to configure and synchronize complex measurements without
having to send the routing commands each time.
The following tables summarizes the commands used to define, execute,
and manage sequences. For more information, see the Programmer’s
Reference Help file on the L4400 series Product Reference CD- ROM.
Sequence Definition
ROUTe:SEQuence:DEFine <name>,
"<commands>"
ROUTe:SEQuence:DEFine? <name> Defines a sequence.
Returns sequence definition.
Sequence Execution
ROUTe:SEQuence:ABORT
ROUTe:SEQuence:BUSY?
ROUTe:SEQuence:RUNNing:NAME?
ROUTe:SEQuence:TRIGger[:IMMediate]
ROUTe:SEQuence:WAIT Terminates currently-running sequence.
Returns “1” if sequence is executing (busy).
Returns name of currently-running sequence.
Executes specified sequence.
Blocks until sequence has completed.
