WAVEFORM TRANSFER
WAVEFORM, WF
Command/Query
DESCRIPTION
A WAVEFORM command transfers a waveform from the controller to
the oscilloscope, whereas a WAVEFORM? query transfers a waveform
from the oscilloscope to the controller.
WAVEFORM stores an external waveform back into the oscilloscope’s
internal memory. 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).
See Chapter 4 for further information on waveform structure.

: You can restore to the oscilloscope only complete
waveforms queried with WAVEFORM? ALL .
The WAVEFORM? query instructs the oscilloscope to transmit a
waveform to the controller. The entities can be queried
independently. If the ALL parameter is specified, all four or five
entities are transmitted in one block in the order enumerated above.
