Specifications

Using the DIGitize Command
The DIGitize command is a macro that captures data satisfying the
specifications set up by the ACQuire subsystem. When the digitize process is
complete, the acquisition is stopped. The captured data can then be
measured by the instrument or transferred to the controller for further
analysis. The captured data consists of two parts: the waveform data record
and the preamble.
Ensure New Data is Collected
After changing the oscilloscope configuration, the waveform buffers are
cleared. Before doing a measurement, the DIGitize command should be sent to
the oscilloscope to ensure new data has been collected.
When you send the DIGitize command to the oscilloscope, the specified
channel signal is digitized with the current ACQuire parameters. To obtain
waveform data, you must specify the WAVEFORM parameters for the
waveform data prior to sending the :WAVEFORM:DATA? query.
Set :TIMebase:MODE to NORMal when Using :DIGitize
:TIMebase:MODE must be set to NORMal to perform a :DIGitize or to perform
any WAVeform subsystem query. A "Settings conflict" error message will be
returned if these commands are executed when MODE is set to ROLL, XY, or
DELayed. Sending the *RST (reset) command will also set the time base mode
to normal.
The number of data points comprising a waveform varies according to the
number requested in the ACQuire subsystem. The ACQuire subsystem
determines the number of data points, type of acquisition, and number of
averages used by the DIGitize command. This allows you to specify exactly
what the digitized information contains.
