The Root Level commands control many of the basic operations of the
digitizer.
Command
:DIGitize
The command initializes the selected channels, then starts acquisition of
ADC samples into capture memory. When all waveforms are completely
acquired, the acquisition is stopped.
In Direct mode the captured ADC samples are displayed in the time and
frequency domain windows of the GUI. In DDC mode they are only
displayed in the frequency domain window.
When the digitizer receives this command, it initializes the selected
channels according to the current acquire and trigger settings. It sets the
Memory Capture in Progress bit of the Memory Capture Status Subsystem
and returns to the caller. When the capture is completed, the Memory
Capture in Progress bit is reset to 0. Before reading the data from the
capture memory using the :WAVeform:DATA query, the caller should
verify, that the Capture in Progress bit is 0. For more information on
Memory Capture Status Subsystem, refer to
Subsystem
Command
:DIGitize:NDISplay
Same as the :DIGitize command, but the GUI displays are not updated.
Command
:RUN
This command is equivalent to repetitively calling the :DIGitize command.
Command execution can be stopped with the :STOP command.
Command
:STOP
