Waveform 
Memory Depth 
The memory depth is limited to 1 M points when 
both channels are activated or 2M points when 
only a single channel is activated. The signal must 
be triggered /stopped to have access to the full 
memory depth. Therefore when a signal is saved 
the waveform will be automatically stopped if it is 
not manually triggered /stopped first. 
There are a number of conditions when all of the 
available memory is not utilized due to a limited 
number of different sample rates. This can be 
caused by an un-triggered signal, or a time/div 
setting that is too fast to display all the points on 
screen. 
 
 
Note: 2M point memory lengths are only available 
for time bases slower than 10ns/div on a single 
channel, and 1 M point memory lengths are only 
available for time bases slower than 25ns/div on 
two channels.
