MARK COMMANDS

MARK

CNXT
CPRV
MDEL
MACT?
MBIN? i
MTXT (?) i {,s}
The MARK command is just like pressing the [MARK] key. A mark will be
placed in the data buffer at the next sample. This command has an effect
only when a scan is in progress.
The CNXT command moves the cursor of the active chart display to the
next mark to the right. If the mark is off the right edge of the graph, then
the display is panned to the right until the next mark is found.
The CPRV command moves the cursor of the active chart display to the
next mark to the left. If the mark is off the left edge of the graph, then the
display is panned to the left until the next mark is found.
The MDEL command is just like pressing the Marker Delete softkey. This
command will delete the nearest mark to the left of the cursor.
The MACT? command queries the number of active marks (0-8). If the
number of active marks is greater than 0, then the number of marks is
followed by the active mark numbers, separated by commas. For exam-
ple, if MACT? returns 3,0,2,6 then there are 3 active marks - mark #0, #2
and #6.
The MBIN?i command queries the bin number of mark #i. Remember, all
displays use the same marks. If mark #i is not active, then -1 is returned.
With the mark bin number, use TRCA? to read the trace data at mark #i.
The MTXT command sets or queries the label field for mark #i.
Remember, all displays use the same marks. The parameter i must
select an active mark (0-7). Use MACT? to determine which marks are
active. MTXT?i reads the label field for mark #i. The default label is the
date and time. The MTXT i,s sets the mark label to string s. Spaces are
not recognized, use '_' (underbar) instead.
