Table 28-1 ACQuire Parameter Values
Parameter Value
count_arg An integer that specifies the
number of averages to be taken of
each time point. The choices are
2, 4, 8, 16, 32, 64, 128, or 256.
Acquisition Type Normal
In the Normal mode, with the ACCumulate command OFF, the oscilloscope
acquires waveform data and then displays the waveform. When the
oscilloscope makes a new acquisition, the previously acquired waveform is
erased from the display and replaced by the newly acquired waveform. When
the ACCumulate command is ON, the oscilloscope displays all the waveform
acquisitions without erasing the previously acquired waveform.
Acquisition Type Average
In the Average mode, the oscilloscope averages the data points on the
waveform with previously acquired data. Averaging helps eliminate random
noise from the displayed waveform. In this mode the ACCumulate command
is OFF. When Average mode is selected, the number of averages must also
be specified using the COUNt command. Previously averaged waveform data
is erased from the display and the newly averaged waveform is displayed.
