La Sample Rate - Rigol MSO4000 Series User Manual

Chapter 4 Sample System Setting

LA Sample Rate

The LA sampling refers to the process that the oscilloscope samples the compared
digital signals at a certain time interval. The LA sample rate is the reciprocal of the
time interval. For example, the oscilloscope with 1 GHz LA sample rate samples
digital signals every 1 ns.
Note: The digital signal mentioned here refers to the signal generated by comparing
the input signal with the threshold level specified by users. The input signal is judged
as logic high level when its amplitude is greater than the threshold level and logic low
level when its amplitude is lower than the threshold level.
The digital channel sample rate of MSO4000/DS4000 is up to 1 GSa/s (per channel).
The current LA sample rate is displayed in the LASaRate menu (press Acquire 
LASaRate). You can change the LA sample rate indirectly by modifying the
horizontal time base (refer to "To Adjust the Horizontal Time Base") or memory
depth (refer to "To Set the Memory Depth").
