Sequences
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 Agilent 34980A
Programmer’s Reference Help file.
Defining a Sequence
A sequence defines a series of SCPI commands with an associated name.
When the sequence is first defined, the commands are compiled and then
stored in a compressed format in non- volatile memory. The following SCPI
commands are allowed in a sequence definition (all other commands will
generate an error).
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.
Sequence Management
ROUTe:SEQuence:CATalog?
ROUTe:SEQuence:DELete:ALL
ROUTe:SEQuence:DELete[:NAME] <name>
Returns list of defined sequence names.
Deletes all sequences from memory.
Deletes specified sequence from memory.
Alarm Limits
OUTPut:ALARm{1-4}:SEQuence?
ROUTe:SEQuence:TRIGger:SOURce <name>, <source>
ROUTe:SEQuence:TRIGger:SOURce? <name>
Returns sequence associated with alarm.
Assigns trigger source to sequence.
Returns trigger source currently selected.
