Syntax
MARK:TOTal?
MARK:USERLIST
The command creates a single user mark on a waveform in the time domain. The
arguments consist of an enumeration specifying the source waveform, followed
by 7 time mark parameters. You can create up to 1,024 marks. To save all the
marks to memory, use the command
MARK:SAVEALL TOUSER.
The query form retrieves a list of all user marks, separated by a semicolon.
To retrieve the list of all system generated marks, use the command
SEARCH:SEARCH<x>:LIST?
A "Settings conflict" error event is set for the command form if any of the
following conditions are true:
The source waveform is not turned on.
The position of the mark is not on the waveform.
The maximum number of marks would be exceeded.
NOTE. The search marks returned from the
MARK:USERLIS T?
query are those
marks saved to the internal user list of marks. The search marks returned by the
SEARCH:SEA RCH:LIST?
query are the automatically generated system marks.
