DIGital:TRACe:CATalog?
[SOURce:]DIGital:TRACe:CATalog? lists the currently available data blocks.
Parameters None.
Comments • This command catalogs all blocks in VME memory and all blocks in the
mainframe system memory.
• The command returns a string.
Example DIG:TRAC:CAT? would return this string if both alpha and beta had been
previously defined; "alpha","beta".
DIGital:TRACe[:DATA]
[SOURce:]DIGital:TRACe[:DATA] <name>,<block_data> writes a block of data
to a previously defined user memory block.
Parameters
Comments • <name> must have been previously defined by a DIGital:TRACe:DEFine
command.
• The maximum length for <name> is 12 characters.
• <block_data> is of the form <#digits><length><block> where:
<#digits> tells how many digits are used to define <length>;
<length> tells how many bytes are to be transferred in <block>;
<block> contains the actual data to transfer.
Example DIG:TRAC:DATA first_block,#210ABCDEFGHIJ sends the data “ABCDEFGHIJ”
to the user memory block first_block. Since the ASCII character A has a decimal
value of 65, the equivalent of 65 is stored in the first byte of first_block (and so on).
