27 Root Level Commands
:DIGitize
Command :DIGitize [CHANnel<N> | DIGital<M> | COMMonmode<P> | DIFFerential<P>
| POD<P>][,...]
<N> An integer, 1-4.
<M> An integer, 0-15.
<P> An integer, 1-2.
The COMMonmode and DIFFerential sources are just aliases that can be
used in place of the channel names to apply to differential or common
mode signals. These are just aliases - no state change occurs if you refer
to a differential channel and you are not in differential mode.
DIFFerential1 refers to the differential signal between channels 1 and 3
(and COMMonmode1 refers to the common mode channel between these
same channels). DIFFerential2 refers to the differential signal between
channels 2 and 4 (and COMMonmode2 refers to the common mode
channel between these same channels).
The :DIGitize command invokes a special mode of data acquisition that is
more efficient than using the :RUN command. This command initializes the
selected channels or functions, then acquires them according to the
current oscilloscope settings. When all waveforms are completely acquired,
the oscilloscope is stopped. The waveform completion criteria is set with
the ":ACQuire:COMPlete" command.
If you specify channel parameters, then these are the only waveforms
acquired and the display waveforms of the specified channels are turned
off.
If you use the :DIGitize command with no parameters, the digitize
operation is performed on the channels that are being displayed in the
Infiniium waveform viewing area. In this case, the display state of the
acquired waveforms is not changed after the :DIGitize command is
completed. Because the command executes more quickly without
parameters, this form of the command is useful for repetitive measurement
sequences. You can also use this mode if you want to view the digitize
results because the display state of the digitized waveforms is not affected.
See the Chapter 38, “Sample Programs,” starting on page 1173 for
examples of how to use :DIGitize and its related commands.
NOTE
Full Range of Measurement and Math Operators are Available
Even though digitized waveforms are not displayed, you may perform the full range of
measurement and math operators on them.
