Time stamping is not valid in burst mode or when the output format is binary.  Additionally,
relative time stamping is invalid when attempting to use it in conjunction with continuous,
gap-free acquisitions with two time bases.

For further monitoring and analysis of alarm conditions, the states of the 32 alarm outputs can be stamped to
scan in real time.  Alarm stamping can be enabled with the 

A#1

 command and disabled with the A#0 command.

If Digital Input Stamping (

I#

) is also enabled, it will be appended after the Alarm Stamp (
