The query command transfers the specified file from the instrument to the GPIB-bus
and then on to the controller. It is important to ensure that the intermediate memory on
the controller is large enough to take the file. The setting for the GPIB-bus terminator is
irrelevant.
Tip: Use this command to read/transfer stored instrument settings or waveforms
directly from/to the instrument.
Parameters:
<BinaryBlock> #<number><length_entry><data>
#
: Hash sign; always comes first in the binary block
<number>
: the first digit indicates how many digits the subse-
quent length entry has
<length_entry>
: indicates the number of subsequent bytes
<data>
: binary block data for the specified length.
For files with a size with more than 9 digits (Gigabytes) the
instrument allows the syntax
#(<Length>)
, where
<Length>
is the file size in decimal format.
Parameters for setting and query:
<Filename> string
String parameter to specify the name of the file.
Example: MMEMory:DATA 'D:\user\test.txt',#15hallo
Writes the block data to the file
test.txt
.
The digit
1
indicates a length entry of 1 digit; the digit
5
indicate
a length of the binary data (
hallo
) in bytes.
MMEMory:DATA? 'D:\user\test.txt'
sends the data of the file
test.txt
from the instrument to the
controller in the form of a binary block.
Response: #15hallo
Usage: SCPI confirmed
:MMEMory:DCATalog? <path>
Returns the subdirectories of a particular directory.
Query parameters:
<path> String parameter to specify the directory. If the directory is omit-
ted, the command queries the content of the current directory,
queried with
:MMEMory:CDIRectory
command.
Return values:
<Catalog> <file_entry>
Names of the subdirectories separated by colons. The first two
strings are related to the parent directory.
Example: See "Working with Files and Directories" on page 547.
Usage: Query only
