Select Standard if you want to use this pattern as a standard pattern.
Pattern Type
Select Alternate if you want to define two alternating patterns A and B.
On changing the pattern type, you have the conversion options given below.
For converting an Alternate Pattern to a Standard Pattern:
•
Discard A - Discard the A part of the Alternate pattern and use the B part for
the Standard pattern.
•
Discard B - Discard the B part of the Alternate pattern and use the A part for
the Standard pattern.
•
Multiplex ABAB... - Multiplex the Alternate pattern into the Standard pattern
starting with A.
•
Multiplex BABA... - Multiplex the Alternate pattern into the Standard pattern
starting with B.
By default, the pattern length is not changed when selecting one of the Multiplex
conversions. If the created Standard pattern shall contain all of the bits of the
Alternate pattern, then the Length in Bits has to changed manually.
For converting a Standard Pattern to an Alternate Pattern:
•
A=Pattern, fill B with 0 - The content of the Standard pattern is copied to the
A part of the Alternate Pattern. The B part is filled with 0.
•
B=Pattern, fill A with 0 - The content of the Standard pattern is copied to the
B part of the Alternate Pattern. The A part is filled with 0.
•
Demultiplex - The even bits of the Standard pattern will be used for pattern
A and the odd bits of the Standard pattern will be used for pattern B.
The pattern length will not be adopted automatically when selecting
Demultiplex, By default the pattern length will be kept at the original value and
the pattern is being filled with 0 bits. In case that the converted Alternate
pattern shall only contain bits of the original Standard pattern, set the Length
in Bits to half the pattern length before clicking OK.
