DESCRIPTION A WAVEFORM? Query transfers a waveform
from the oscilloscope to the controller.
A waveform consists of several distinct
entities:
1. the descriptor (DESC)
2. the user text (TEXT)
3. the time (TIME) descriptor
4. the data (DAT1) block, and, optionally
5. a second block of data (DAT2)
The WAVEFORM? Query instructs the
oscilloscope to transmit a waveform to
the controller. The entities may be
queried independently. If the “ALL”
parameter is specified,all four or five
entities are transmitted in one block in
the order enumerated above.
Note: The format of the waveform data
depends on the current settings specified
by the last WAVEFORM_SETUP
command.
