Memories (Reference Waveforms)
Memories are traces stored for reference. They can be recalled to the
display for comparison with other traces. A memory can be zoomed or
measured for better analysis of historical data. You can store up-to-four
internal memories (M1-M4). After that, new memories will overwrite
previously stored data.
Internal memories only persist until the oscilloscope is rebooted. To
store memories indefinitely, save them to an external file by choosing
File > Save Waveform. The file can then be recalled into one of the four
internal memories for viewing by choosing File > Recall Waveform. Only
memory files saved with the extension .trc can be recalled.
Press the front panel Mem(ory) button to open the Memory dialog.
To turn on stored memory, check On next to M1-M4.
To store new memory, touch M1-M4 button or tab.
