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.
