ACQuire:MODe
Sets or queries the acquisition mode of the oscilloscope. This affects all live
waveforms. This command is equivalent to setting Mode in the Acquire menu.
Waveforms are the displayed data point values taken from acquisition interĆ
vals. Each acquisition interval represents a time duration that is determined
by the horizontal scale (time per division). The oscilloscope sampling system
always samples at the maximum rate, and so an acquisition interval may
include more than one sample.
The acquisition mode, which you set using this ACQuire:MODe command,
determines how the final value of the acquisition interval is generated from
the many data samples.

SAMple specifies that the displayed data point value is simply the first
sampled value that was taken during the acquisition interval. In sample mode,
all waveform data has 8 bits of precision. You can request 16 bit data with a
CURVe? query, but the lowerĆorder 8 bits of data will be zero. SAMple is the
default mode.
PEAKdetect specifies the display of the highĆlow range of the samples taken
from a single waveform acquisition. The oscilloscope displays the highĆlow
range as a vertical column that extends from the highest to the lowest value
sampled during the acquisition interval. PEAKdetect mode can reveal the
presence of aliasing.
AVErage specifies averaging mode, where the resulting waveform shows an
average of SAMple data points from several separate waveform acquisitions.
The number of waveform acquisitions that go into making up the average
waveform is set or queried using the ACQuire:NUMAVg command.
