:MEMory:FILE:LIST:DATA
:MEMory:FILE:LIST:DATA {<”filename”>},
:MEMory:FILE:LIST:DATA? {<”filename”>}
The command writes data to a list file. If the file name is omitted, data will be loaded to the list RAM.
The RAM list will be played when enabling the list mode.
The query returns list file data. If the file name is omitted, list RAM data will be returned.
Data sent or received has IEEE488.2 definite block data format:
#{
specifies how many digits are contained in .
specifies how many data bytes follow in .
Example of definite block data:
#221130000000;1.1;0.1;0.1
#221…: byte count is two digits wide
#221…: 21 data bytes will follow
…130000000;1.1;0.1;0.1: 21 bytes of data
The list itself consists of values separated by semicolon “;” and rows separated by carriage return “\r”
and/or newline “\n”. Four values (frequency in Hz, power in dBm, dwell time in s, delay time in s) make
a row. Each row defines one point of the list.
Example of a two points list (first point 130 MHz, 1.1 dBm, 100 ms on, 100 ms off; second point 130
MHz, 1 dBm, 100 ms on, 100 ms off):
130000000;1.1;0.1;0.1\r\n
140000000;1;0.1;0.1\r\n
:MEMory:FILE:LIST:DELete
:MEMory:FILE:LIST:DELete <”filename”>|ALL
This command deletes the specified list file. Passing ALL deletes all present list files.
:MEMory:FILE:LIST:LOAD
:MEMory:FILE:LIST:LOAD <”filename”>
This command loads a list file to the list RAM. The RAM list will be played when enabling the list
mode.
:MEMory:FILE:LIST:STORe
:MEMory:FILE:LIST:STORe <”filename”>
This command stores the current list RAM data in a list file.
