Version 1.1 is valid in 2 Channel mode and De-empasis mode. In multiplexer mode
the sequence and block specification for Data Out will only be used, multiplexed
and distributed to both channels automatically.
Explanation of the Keywords:
Language version to allow future extensions. If no version is entered, version 1.0
is assumed.
Examples: Version= 1.0 , Version= 1.1
Descriptive text to be stored with the sequence, given as a double-quoted string.
Example: Description= "Sequence for testing A81397B"
Sets the start condition of the sequence.
Syntax:
Start= IMM[edate] | AuxInHi | AuxInLo | AuxInRising | AuxInFalling | Man[ual]
Input parameters:
• IMM: Sequence starts immediately after sequence download. This is the
default.
