3. Waveform Leakage: when the sample rate is too low, the waveform rebuilt
from the sample data does not reflect all the actual signal information.
LA Sample Rate
LA sampling refers to the process that the oscilloscope samples the compared digital
signal at a certain time interval. LA sample rate is the reciprocal of the time interval.
For example, the oscilloscope with 500 MSa/s LA sample rate samples digital signals
once every 2 ns. The maximum sample rate of the digital channels of the oscilloscope
is 1 GSa/s.
Note:
1. The digital signal mentioned here refers to the signal generated by comparing
the input signal to the threshold specified by users. The comparison rule is that
the input signal is judged as logic high level when it is greater than the threshold
and logic low level when it is lower than the threshold.
2. The LA sample rate is displayed in the LASaRate menu and can be changed
indirectly by adjusting the horizontal time base (s/div) through HORIZONTAL
SCALE or modifying the “Memory Depth”.
