MEMory Subsystem
MEMory commands provide mass storage capability for output measurement data. The mass storage
may be either internal or external to the instrument. The mass storage device is selected using the full
path embedded within the filename. The filename parameter is a string.
MEMory:COPY:TABLe <"name">
Copies the table that was selected with MEMory:TABLe:SELect to non-volatile memory. You can use
the same name or a different name. Table names cannot be longer than 12 alphanumeric characters
and must start with an alpha character. A maximum of 30 tables can be stored in non-volatile
memory. Tables can have from 3 to 1024 points.
Parameter Typical Return
<"name"> the table name (none)
Copies the table named curve1: MEM:COPY:TABL "curve1"
l
The query returns an ASCII string enclosed in double quotes containing the value of the specified
attribute, or a blank string if the name of the attribute is not valid or an error has occurred.
l
After many writes to non-volatile memory, the time it takes to write to memory may increase up to
one second per write operation. If you are copying many tables, this may take up to 10 seconds..
MEMory:DELete[:NAME] <"name">
Deletes the specified table in both volatile and non-volatile memory. This command will delete one
table per execution. If a table is stored in volatile memory and also stored in non-volatile memory with
the same name, the volatile copy will be deleted first. A second MEM:DEL[:NAME] must be sent to
remove the table from non-volatile memory.
Parameter Typical Return
<"name"> the table name (none)
Deletes the table named curve1: MEM:DEL "curve1"
MEMory:DELete:ALL
Deletes all tables in both volatile and non-volatile mass memory. The command fails if a table is
currently selected or activated with the MEMory:TABLe:SELect or CURRent:TABLe:NAME command. If
the command fails, no tables are deleted.
Parameter Typical Return
(none) (none)
Deletes all tables in volatile and non-volatile memory: MEM:DEL:ALL
