[:SOURce]:DM[:BASic]:DATA:FREE?
This command deletes all data lists, with the exception of list "XMEM" (cf Chapter 2, Section "DM
Memory Extension"). *RST has no influence on data lists.
Example: :SOUR:DM:BAS:DATA:FREE? Answer: 2400, 200
[:SOURce]:DM[:BASic]:DATA:SELect "Name"
This command selects the data list indicated. Working with the data list is only possible after
selection. If the list indicated does not exist yet, it is generated. The name may contain up to
seven letters.
List "XMEM" calls the DM memory extension (option SME-B12) (cf. Chapter 2, Section "DM
memory extension"). *RST has no influence on data lists.
Example: :SOUR:DM:BAS:DATA:SEL "DLIST1"
[:SOURce]:DM[:BASic]:DATA:DATA 0 | 1 {, 0 | 1}
This command transmits the bit data the data generator outputs bit by bit to the data list selected
or to the memory area of the DM memory extension indicated (selection list "XMEM", definition of
the memory area under :DM:BAS:DATA:XMEM). Only numbers 0 or 1 are permissible. The data
can also be transmitted as block data. 8 bit data each are combined to form a byte, with the first
bit date having to be saved in the most significant bit of the first data byte. The following examples
of commands are equal. If the data are to be returned as block data, this has to be set in the
FORMat system. In the case of binary-block transmission, only lists with a length of integral
multiples of 8 can be loaded; when the data are returned, the last byte is filled if necessary. RST
has no influence on data lists.
Example:
:SOUR:DM:BAS:DATA:DATA 0,1,1,0,0,0,0,1,0,1,0,1,1,0,0,0,0,0,1,0,1,1,0,1
:SOUR:DM:BAS:DATA:DATA #13aX- (s.a. ’block data’ in chap. ’Parameter’)
[:SOURce]:DM[:BASic]:DATA:DATA:POINts?
This command queries the length (in bits) of the DATA list presently selected. The command is a
query and thus has no *RST value.
Example: :SOUR:DM:BAS:DATA:DATA:POIN? Answer: 200
[:SOURce]:DM[:BASic]:DATA:ATTenuate 0 | 1 {, 0 | 1}
This command transmits the bit edgedata the data generator uses for the decision of whether the
level is to be reduced or not (see SOURce:DM:BAS:DATA:ALEVel as well). List "XMEM",
DM memory extension, can only be written into with ATTenuate data if
DM:BAS:DATA:XMEM:MODE is set to ALL.Only numbers 0 or 1 are permissible. The data can also
be transmitted as block data (cf. DATA). *RST has no influence on data lists.
Example: :SOUR:DM:BAS:DATA:ATT 1,1,1,0,0,0,0,...
[:SOURce]:DM[:BASic]:DATA:ATTenuate:POINts?
This command queries the length (in bits) of the ATTenuate list presently selected. The
command is a query and thus has no *RST value.
Example: :SOUR:DM:BAS:DATA:ATT:POIN? Answer: 200
