<data> is the cu
rve data.
<newline> is a single byte new line character at the end of the data.
<asc cu rve> is the waveform data in ASCII format. The format for ASCII data
is
<NR1> [,<NR1>...], where each < NR1> represents a data point.
Examples
CURVE? with ASCII enco
ding, start and stop of 1 and 10 respectively, and a width
set to 1 might return
:CURVE 61 ,62,61,60,60,-59 ,-59,-58,-58,-59
NOTE. Curve data is transferred from the oscilloscope asynchronously, depending
on the length of the curve record. Such transfers may require several seconds
to complete. During this period, the oscilloscope will not respond to the user
controls. You can interrupt these asynchronous data transfers by sending a device
clear message to th
e oscilloscope or by interrupting the query with another
command or query. In order to verify that curve data has been completely
transferred, it is recommended that you follow such queries with an *ESR?
query to verify there are no error bits set. You can also check the event que ue to
determine the cause of the error. If the error was caused by an interrupted query,
then the asynchronous data transfer was not complete when the *ESR? query was
sent. In such cas
es, it may be necessary to increase the program's time-out value
to ensure that all data is transferred and read.
DATa
Sets or returns the format and location of waveform data transferred with the
CURVe? query o
r CURVe command.

WFMOutpre:NR_Pt?
Arguments
INIT initializes the waveform data parameters to their factory defaults except for
DATa:STOP, which is set to the current acquisition record length.
SNAp sets DATa:STARt and DATa:STOP to match the current waveform cursor
positions.
