Technical data

• For 4-bit packed data, the <block data> required to set the same pattern would
be:
#1255
• For 1-bit packed data, the <block data> would be as follows:
#1801010101
SENSe[1]:PATTern:UPATtern<n>:IDATa[?]
IAgilentN490xEDPatternfile.SetDataBlock (IVI-compliant)
SENSe[1]:PATTern:UPATtern<n>:IDATa [A|B,] <start_bit>, <length_in_bits>,
<block_data>
SENSe[1]:PATTern:UPATtern<n>:IDATa? [A|B,] <start_bit>, <length_in_bits>
The query returns the selected bits of the standard (A) or alternate (B) pattern of
the file found under <filename>.
This command is used to set specific bits in a user pattern. It is similar to the :DATA
command. The :IDATa command is a contraction of the phrase Incremental
DATA and is used to download part of a user-defined pattern.
The parameters have the following meanings:
Table 61
Parameter Description
[A|B] Defines for which pattern the data is to
be set (A = standard pattern, B =
alternate pattern). If the pattern file
describes a standard pattern (:USE =
STRaight), this parameter cannot be B.
<filename> Name of the file being defined. If the file
does not exist, it is created.
<start bit> First bit to be overwritten (starting with
0).
<length_in_bits> Number of bits to be overwritten.
