OPATtern
Command:MACHine{12}:TWAVeform:OPATtern <label_name>, <label_pattern>
The OPATtern command allows you to construct a pattern recognizer term for the O marker which is then used with the OSEarch criteria and OCONdition when moving the marker on patterns. Since this command deals with only one label at a time, a complete specification could require several invocations.
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{01X} . . . #Q{01234567X} . . . #H{0123456789ABCDEFX} . . . {0123456789} . . . }"

Query | :MACHine{12}:TWAVeform:OPATtern? <label_name> |
The OPATtern 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 O marker for a given label. If the O marker is not placed on valid data, don’t cares (X) are returned.
