NOTE. Curve dat
a 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 the oscilloscope or by interrupting the query with another
command or query. In order to verify that curve data has been completely
transferre
d, 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 queue to
determine the cause of the error, if any. 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 cases, it may be necessary to increase the program's
time-out value to ensure that all data is transferred and read.
DATa
These commands specify the format and location of waveform data that is
transferred using the CURVe command, or return the format and location of the
waveform data that is transferred with the CURVe? query. You can use the
INIT
argum
ent to reset all of the
DATa parameters to default values. (Note that the *RST
and FACtor y commands do not reset the DATa parameters.) You can use the
SNap argument to automatically set the DATa:STARt and DATa:STOP values to
the starting and stopping point of the waveform cursors (if on). Note that setting
DATa:STARt and DAT a:STOP automatically sets WFMOutpre:NR_Pt.
