Parameter Description
<block data> The data that describes the pattern (see
“[SOURce[1]]:PATTern:UFILe:DATA[?] ”
on page 119 for the description).
The use of the parameters can be best illustrated by an example. If we have an
alternate 16-bit pattern of 0s only, and we want to set the last four bits to 1s, the
IDATa command would appear as follows:
• If the data packing is 8:
SOURce1:PATTern:UFILe:IDATa B, <filename>, 12, 4, #11(&F0) (where (&F0)
is replaced by the ASCII representation of the value)
• If the data packing is 4:
SOURce1:PATTern:UFILe:IDATa B, <filename>, 12, 4, #11F
• If the data packing is 1:
SOURce1:PATTern:UFILe:IDATa B, <filename>, 12, 4, #141111
The response form returns <block data> at the specified location.

See “Working with User Patterns in SCPI” on page 63 for more information on using
this command.
[SOURce[1]]:PATTern:UFILe[:LENGth][?]
IAgilentN490xLocalPatternfile.Length (IVI-compliant)
[SOURce[1]]:PATTern:UFILe[:LENGth] <filename>, <NR1>
[SOURce[1]]:PATTern:UFILe[:LENGth]? <filename>
This command sets the length of a user pattern file. The query returns the length
of the user pattern file. If an alternate pattern is selected (:USE APATtern), the
LENGth command sets the length of each half of the pattern.
Note that the :DATA command automatically sets the length of the file.
See “Working with User Patterns in SCPI” on page 63 for information on using this
command.
