•
Recall Setup Recalls the previously stored front-panel setup that was
saved with the waveform for the trace selected.
•
Edit Label
Used to enter a 20 character label that identifies the stored
waveform. See "Create a Label for Trace Memory" later in this chapter for
more information.
3
Turn the knob closest to the
Cursors
key to move the cursor in
the character area to select the desired trace location (from 1 to
100).
Trace status is displayed on the screen. Information includes the edit label
(or trace number if label has not been entered), and the time and date the
memory was saved or cleared.
4
Select the desired softkey ( Save , Clear , or Recall ).
Saving Traces Hint
For traces 1 to 3, the trace is saved in the non-compressed state. For traces
greater than 3, the trace is saved in 64 Kbytes of nonvolatile trace memory with
data compression. After a compressed trace is saved, the available area (in
percent) is displayed.
The number of traces that can be saved in 64 Kbytes of nonvolatile trace
memory is dependent on the trace complexity and the current oscilloscope
configuration. For example:
Up to 97 simple traces (e.g., square wave) can be stored.
As few as four complex traces (AM modulated sine wave) can be stored.
Saving a trace with autostore information or the grid takes more memory.
In most cases, if the information is not needed, turn it off to save memory.
The data compression algorithm uses run length encoding to compress the data.
Where possible, runs of identical bits are stored as a single word
(1 identification bit and 15 length bits).
The Review Traces feature is useful when observing test failures.
To store only the front-panel setup, blank the screen prior to saving the trace.
The edit label function can be used to identify the setup.
