Figure 8-1: History memory. In this example, the memory can store 10 waveforms.
The number of stored history waveforms depends on the memory size, the number of
enabled channels, and the record length. The shorter the record length, the less the
number of channels, and the larger the memory, the more history waveforms are
saved.
You can work with history waveforms in the same way as with the waveform of the lat-
est acquisition: use zoom, cursors, measurements, create math waveforms and so on.
You can also save a single history waveform for further analysis.
8.3.2 History setup
The "History" dialog contains the complete functionality on history viewing and informa-
tion.
The most important information and functions are also provided in the quick-access
history dialog box.
Access: "Menu" > "Acquisition" > "History" tab.
