Parameter Description
<block data> The data that describes the pattern (see
“SENSe
[1]:PATTern:UPATtern<n>:DATA[?] ” on
page 254 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:
SENSe[1]:PATTern:UPAT1:IDATa B, <filename>, 12, 4, #11(&F0) (where (&F0)
is replaced by the ASCII representation of the value)
• If the data packing is 4:
SENSe[1]:PATTern:UPAT1:IDATa B, <filename>, 12, 4, #11F
• If the data packing is 1:
SENSe[1]:PATTern:UPAT1: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.
SENSe[1]:PATTern:UPATtern<n>[:LENGth][?]
IAgilentN490xEDPatternfile.Length (IVI-compliant)
SENSe[1]:PATTern:UPATtern<n>[:LENGth] <NR1>
SENSe[1]:PATTern:UPATtern<n>[:LENGth]?
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 sets the length of the file.
See “Working with User Patterns in SCPI” on page 63 for information on using this
command.
