The next two topics describe each of the types of acquisition modes
and their differences.
Sample. Use Sample acquisition mode to acquire 2,500 points and
display them at the SEC/DIV setting. Sample mode is the default
mode.
1 2 3 4 5 6 7 8 9 10
Sample acquisition intervals (2500)
Sample mode acquires a single sample point in each interval.
Sample points
The maximum sample rate is 1 GS/s. At 100 ns and faster settings,
this sample rate does not acquire 2,500 points. In this case, a Digital
Signal Processor interpolates points between the sampled points to
make a full 2,500 point waveform record.
Peak Detect. Use Peak Detect acquisition mode to detect glitches as
narrow as 10 ns and to limit the possibility of aliasing. This mode is
effective when at 5
m
s/div or slower.
