To save or recall traces
With the Measurement/Storage Module installed, the two volatile pixel
memories are replaced with four high-speed non-volatile memories.
In addition, 64 Kbytes of nonvolatile trace memory with data compression is
also provided. A data compression algorithm maximizes the number of traces
and front-panel setups that can be stored into this memory.
The total number of traces that can be saved depends on the complexity of
each trace. At least 4 highly complex traces, or up to 96 simple traces, can
be saved in this 64 Kbytes of memory. Storage time is less than 10 seconds.

Adjust Oscilloscope controls for desired stable display.
2 Press Trace .
A softkey menu with six choices appears. All of them are related to the trace
memories of the module.
Trace Selects the trace memory (ALL, 1 to 100). When ALL is selected,
four additional softkeys are displayed.
a All Off Used to turn all 100 trace memories to off.
b All On Used to turn all 100 trace memories to on.
c Clear All Used to clear the contents of all 100 trace memories at
one time.
d Review Traces Used to view the contents of all trace memories
(with stored data) one at a time. View time is approximately 3
seconds. When selected, two additional softkeys are displayed.
Pause Review pauses review cycle on current trace until key is
pressed again, and Cancel Review cancels the review cycle.
Trace X Off On Turns the selected memory number to on or off. When on
is selected, trace status is temporarily displayed on the screen.
Save to Trace X Saves the currently displayed waveform and front-panel
setup to the selected trace memory location.
Clear Trace X Erases a previously stored waveform and front-panel setup
from the selected trace memory location.
