3 Features and Functions
Deleting Sequences
You can delete sequences from the front panel or over the remote
interface. Deleting a sequence also frees up space in non- volatile memory
previously allocated for the sequence.
• If you attempt to delete a sequence name that is not currently stored 
in memory, an error will be generated.
• If you attempt to delete a sequence while it is executing, an error 
will be generated. To abort a sequence execution, use the
ROUTe:SEQuence:ABORt command or a Device Clear.
• Deleting a sequence will remove its association with an alarm if used
(see “Executing a Sequence on an Alarm Condition” on page 145 for
more information).
Front Panel Operation: Sequence > DELETE|DELETE ALL
Remote Interface Operation: The following command deletes the sequence
named “MYSEQ_1”.
ROUT:SEQ:DEL MYSEQ_1
The following command deletes all sequences from memory.
ROUT:SEQ:DEL:ALL
Reading the List of Stored Sequences
From the remote interface only, you can read the names of all sequences
currently stored in memory.
• When stored in memory, the user- defined sequence names are
converted to all uppercase letters. For example, when stored “MySeq_1”
is converted to “MYSEQ_1”.
• Up to 500 unique sequences can be stored in non- volatile memory.
Each sequence is limited to 1024 bytes.
Remote Interface Operation: The following command returns a
comma- separated list of sequence names currently stored.
ROUT:SEQ:CAT?
The above command returns a string in the form:
MYSEQ_1,PATH_DUT1,SW_PATH2
If no sequence names have been stored, a null string (“ ”) string 
is returned.
