Waveform Acquisition

Based on the data that has been stored in the acquisition memory, the DL850E/DL850EV performs
various operations, such as displaying waveforms on the screen, computing, measuring cursors, and
automatically measuring waveform parameters.
You can set the number of data points to store in the acquisition memory (the record length), enable or
disable the sample data averaging feature, and so on.
Record Length
Record length refers to the number of data points that are stored to the acquisition memory for each
channel. Display record length refers to the data points from the data stored in the acquisition memory
that are displayed on the screen. Normally, the acquisition-memory record length and display record
length are the same, but the time axis setting may cause them to differ. When you change the time
axis setting, the sample rate and record length also change.
On the standard model of the DL850E/DL850EV, you can set the record length to a value between 1
kpoint and 250 Mpoint. Depending on the model, you can set the record length to a value of up to 2
Gpoint.
Acquisition Mode
Specify how the DL850E/DL850EV processes the sampled data, stores it in the acquisition memory,
and uses it to display waveforms. There are four acquisition modes: Normal, Envelope, Averaging, and
BoxAverage.
