ACQuire:MODe
Description
This command sets or queries the acquisition mode of the instrument.
This affects all live waveforms. This command is equivalent to select-
ing Horizontal/Acquisition from the Horiz/Acq menu, and then choos-
ing the desired mode from the Acquisition Mode group box.
Waveforms are the displayed data point values taken from acquisition
intervals. Each acquisition interval represents a time duration set by the
horizontal scale (time per division). The instrument 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 com-
mand) determines how the final value of the acquisition interval is gen-
erated from the many data samples.

Arguments
H SAMple
Specifies that the displayed data point value is the first sampled value
that is taken during the acquisition interval. In sample mode, all wave-
form data has 8 bits of precision. You can request 16 bit data with a
CURVe? query but the lower--order 8 bits of data will be zero.
SAMple
is the default mode.
H PEAKdetect
Specifies the display of high --low range of the samples taken from a
single waveform acquisition. The high --low range is displayed 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 or narrow spikes.
H HIRes
Specifies Hi Res mode where the displayed data point value is the
average of all the samples taken during the acquisition interval. This
is a form of averaging, where the average comes from a single wave-
