Control Description
For record sizes between 1,000,000 and the oscilloscope memory limit
(usually many tens or hundreds of megapoints), it is essential to break
processing into blocks to avoid running out of processor memory. In
addition, since neither the entire waveform, nor the entire processed
variables will
fi t in computer memory at one time, it is necessary to make
some decisions as to what information will be retained as each block is
processed. By default, raw data, electric
fi eld values, and other time
series data are not aggregated over all blocks in a record greater than
1,000,000 samples. (See page 53,
Managing data sets with record length
> 1,000,000 .)
Run-Stop The Run button repeatedly takes Single acquisitions until stopped.
Single The Single button takes a single waveform acquisition for processing and
data display.
Scale controls Provides convenient access to change the plot scale setting. Click on the
icons to increment or decrement the setting.
Other controls Other controls will display depending on the selected plots or
measurements.
