XPATtern
Command :MACHine{1|2}:TWAVeform:XPATtern
<label_name>,<label_pattern>
The XPATtern command constructs a pattern recognizer term for the
X marker which is then used with the XSEarch criteria and XCONdition when
moving the marker on patterns. Since this command deals with only one
label at a time, a complete specification could require several iterations.
When the value of a pattern is expressed in binary, it represents the bit
values for the label inside the pattern recognizer term. In whatever base is
used, the value must be between 0 and 232 1, since a label may not have
more than 32 bits. Because the <label_pattern> parameter may contain
don’t cares, it is handled as a string of characters rather than a number.
<label_name> string of up to 6 alphanumeric characters
<label_pattern> "{#B{0|1|X} . . . |
#Q{0|1|2|3|4 |5|6|7|X} . . . |
#H{0|1|2|3|4 |5|6|7|8|9|A|B |C|D|E|F|X} . . . |
{0|1|2|3|4|5 |6|7|8|9} . . . }"

Query :MACHine{1|2}:TWAVeform: XPATtern? <label _name>
The XPATtern query, in pattern marker mode, returns the pattern
specification for a given label name. In the time marker mode, the query
returns the pattern under the X marker for a given label. If the X marker is
not placed on valid data, don’t cares (X) are returned.
