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 188 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.
