BASICS
Memories are traces stored for reference that 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-twelve internal memories (M1-M12). After that, new memories will overwrite previously stored data.
Memories (Reference Waveforms)
To recall a stored memory:
Press the front panel Mem(ory) button to open the Memories dialog, then
check On next to M1-M12.
Choose
Math > Memory Setup
. On the M
n
tab, select the trace you want
stored in
Copy From Waveform
, then touch
Copy Now
.
Optionally, add
Notes
or
Labels
to the stored memory.
Then, drag the descriptor box of
the trace you want stored onto
the new M
n
descriptor box.
OR
Touch the
Add New
box and
choose
Memory
to turn on the
next memory trace.
To store a new memory:
Internal memories persist only until the oscilloscope is rebooted. To store
memories indefinitely, save them to a trace (.trc) file by choosing
File > Save Waveform
.
The trace file can later be recalled into one of the internal memories for
viewing by choosing
File > Recall Waveform
. Only files saved with the .trc
extension can be recalled.
