Command Groups
This manual lists the MDO4000C, MDO4000B, MDO4000, MSO4000B,
DPO4000B and MDO3000 Series IEEE488.2 commands in two ways. First,
it presents t
hem by functional groups. Then, it lists them alphabetically. The
functional group list starts below. The alphabetical list provides detail on each
command.
Acquisition C ommand Group
Use the commands in the Acquisition Command Group to set up the modes and
functions that control how the oscilloscope acquires signals input to the channels,
and processes them into waveforms.
Using the commands in this group, you can do the following:
Start and stop acquisitions.
Control whether each waveform is simply acquired, averaged, or enveloped
over successive acquisitions of that waveform.
Set the controls or conditions that start and stop acquisitions.
Contr
ol acquisition of channel waveforms.
Set acquisition parameters.

e 2-13: Acquisition Commands
Command Description
ACQuire?
Ret
urns acquisition parameters
ACQuire:FA STAcq Sets or queries the fast acquisition feature.
ACQuire:FA STAcq:PALEtte Sets (or queries) which palette to use for fast acquisition mode.
ACQuire:FA STAcq:STATE Turns fast acquisition mode on or off, or queries the state of the mode.
ACQuire:MAGnivu This command specifies the MagniVu feature
ACQuire:MAXSamplerate?
Returns the maximum real-time sample rate
ACQuire:MODe Specifies the a cquisition mode of the oscill oscope for all analog channel waveforms.
ACQuire:NUMACq? Returns number of acquisitions that have occurred
ACQuire:NUMAVg This command specifies the number of acquisitions for an averaged waveform
ACQuire:NUMEnv This command controls the number of envelopes (when acquisition mode is set to ENVelope
using ACQ u ire:MODe).
ACQuire:STATE Starts or stops the acquisition system
ACQuire:STOPAfter This command specifies whether the acquisition is continuous or single sequence
