Query
DESCRIPTION
A WAVEFORM? Query transfers a waveform
from the oscilloscope to the controller.

1. The format of the waveform data depends on
the current settings specified by the last
WAVEFORM_SETUP command.
2.The format of the waveform data can be seen
by the TEMPLATE? Query.
QUERY SYNTAX
<trace>: WaveForm? [<section>]
<trace> : = { C1,C2,C3,C4}
<section>: = {DESC, DAT2,ALL}
DESC: Return descriptor. The length of
descriptor is 346 bytes. This includes the
information necessary to reconstitute the
display of the waveform from the data,
including: your oscilloscope name and serial
number, the encoding format used for the data
blocks, and miscellaneous constants.
DAT2:Return the mian data include the head,
the wave data and the ending flag . The length
of data is current memory depth.
ALL: Return the descriptor and data.
RESPONSE FORMAT
<trace>: WaveForm <waveform_data_block>
EXAMPLE
The following command reads waveform data
of Channel 1,and current memory depth is
70pts.
Command message:
