Agilent E1439 Programmer's Reference

Functions listed alphabetically

headerValuePtr

points to the current value of initalValue

incrementCount

specifies the number of automatic increments to the headerIndex bit field. The default
incrementCount is 0 and the maximum value is (2^10 -1).

Example

The following is a example of how the increment process works.

For headerValue = 0x12345678 and incrementCount = 0x2, the sequence of values for
headerValue and headerIndex are:

If an incremented header reaches a value where the headerIndex is 0x3FF, the next headerIndex
will be 0x000, and no carry will be generated to the upper 22 bits of the header.

Note

If the incrementCount is set to 0, incrementing the headerIndex field is disabled.

incrementCountPtr

points to the current value of incrementCount

The following table is a summary of valid fiber, epoch setups. Please note that the designation of
N/A means that this information is not applicable to this condition. In this case the setting is
accepted but ignored. The designation of OK means the setting is accepted and implemented. The
designation of NO means do not use this setting with this condition.
