:DATA:PATTern:IMPort
Syntax :DATA:PATTern:IMPort <pattern-name>, <file-name>
Input
Parameters
<pattern-name>: Specify the pattern name.
<file-name>: Specify the location of the pattern file to be imported.
Description This command imports an N4903B J-BERT pattern or M8020A/M8030A
pattern file.
M8020A/M8030A File Format:
File content consists of a short header and the actual symbol sequence.
The file content looks like the following:
Version=<version>
Use=<num-symbols>[,<symbol-coding>[,<mask-used>[,<squelch-used>,<
error-used>]]]
[Description=<description>]
[Pack=<packing>]
Data=
<data>
Optional lines or fields are enclosed in square brackets. Format and
notation is intended to follow the concepts of the other :DATA:PATTern
SCPI commands.The first line must include a line with the file format
version. Accepted value for <version> is M8000 1.0.0 or M8000 1.0.1.
