Command Syntax
SOURce:SCENario:ADVLOG:HEADer? <logID>
<logID>
— Log identifier that specifies the advanced log for which to obtain the header.
Notes
The position of specific field label within the comma-separated line is the same as the position
of that field’s value within a response line of the
SOURce:SCENario:ADVLOG
command.
In order to be compatible with future versions of the unit firmware, any user-developed soft
ware should not strictly rely on a specific order of fields in responses to the
SOURce:SCENario:ADVLOG?
and
SOURce:SCENario:ADVLOG:HEADer?
com
mands. Before issuing log record requests user-developed software should:
a.
first request the log header once,
b.
then determine positions of all fields of interest based on their labels,
c.
and then refer to log record fields by their determined positions.
The order of fields is fixed within one firmware version.

logID
