:MMEMory:DATA <file_name>[,<binary block data>]
:MMEMory:DATA? <file_name>
Writes the block data <binary block data> to the file identified by <file_name>. The IEC/
IEEE-bus terminator should be set to EOI in order to ensure correct data transfer.
The associated query command transfers the specified file from the instrument to the
IEC/IEEE bus and then on to the control computer. It is important to ensure that the
intermediate memory on the control computer is large enough to take the file. In this case,
the setting for the IEC/IEEE-bus terminator is irrelevant. This command can be used to
read/transfer stored instrument settings or waveforms directly from/to the instrument.
Parameters:
String parameter to specify the name of the file.
Setting parameters:
#<number><length entry><block data>
# always comes first in the binary block
<number> the first digit indicates how many digits the subsequent
length entry has
<length entry> indicates the number of subsequent bytes
<binary block data> binary block data for the specified length.
<file_name>
<binary block data>
MMEM:DATA 'TEST1.WV',#3767<binary data>
writes the block data to the file test1.wv.
The digit "3" indicates a length entry of 3 digits; the digits "767"
indicate a length of the binary data in bytes.
MMEM:DATA? 'TEST1.WV'
sends the data of the file Test1.wv from the instrumenet to the
controller in the form of a binary block.
Example:
:MMEMory:DCATalog?
Returns the subdirectories of the current or specified directory.
Return values:
<file_entry>
Names of the subdirectories separated by colons. The first two
strings are related to the parent directory.
Query parameters:
String parameter to specify the directory. If the direcory is omitted,
the command queries the content of the current directory, queried
with MMEM:CDIR command.
<Dcatalog>
<path_name>
MMEM:DCAT?
Response: 'test', 'wave', 'digital'
the subdirectories test, wave and digital exist in the current
directory.
