:ACQuire Commands
The :ACQuire:TYPE NORMal command sets the oscilloscope in the normal
acquisition mode. For the majority of user models and signals, NORMal
mode yields the best oscilloscope picture of the waveform.
Averaging
The :ACQuire:TYPE AVERage command sets the oscilloscope in the
averaging mode. You can set the count by sending the :ACQuire:COUNt
command followed by the number of averages. In this mode, the value for
averages is an integer from 2 to 65536. The COUNt value determines the
number of averages that must be acquired.
High-Resolution
The :ACQuire:TYPE HRESolution command sets the oscilloscope in the
high- resolution mode (also known as
smoothing ). This mode is used to
reduce noise at slower sweep speeds where the digitizer samples faster
than needed to fill memory for the displayed time range. Instead of
decimating samples, they are averaged together to provide the value for
one display point. The slower the sweep speed, the greater the number of
samples that are averaged together for each display point.
Peak Detect
The :ACQuire:TYPE PEAK command sets the oscilloscope in the peak
detect mode. In this mode, :ACQuire:COUNt has no meaning.
Reporting the Setup
Use :ACQuire? to query setup information for the ACQuire subsystem.
Return Format
The following is a sample response from the :ACQuire? query. In this case,
the query was issued following a *RST command.
:ACQ:MODE RTIM;TYPE NORM;COMP 100;COUNT 8;SEGM:COUN 2
