:ACQuire Commands
Introduction to
:ACQuire
Commands
The ACQuire subsystem controls the way in which waveforms are acquired. These
acquisition types are available: normal, averaging, peak detect, and high
resolution.
Normal
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
