Sample acquisition intervals (2500)
• = Sample points
Sample mode acquires a single sample point in each interval.
The oscilloscope samples at the following rates:
■
Maximum of 2 GS/s for 100 MHz, 150, and 200 MHz models
■
Maximum of 1 GS/s for 50 MHz and 70 MHz models
■
Maximum of 500 MS/s for 30 MHz

At 100 ns and faster settings, this sample rate does not acquire 2500 points. In
this case, a Digital Signal Processor interpolates points between the sampled
points to make a 2500 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 the
horizontal scale setting of 5 ms/division or slower.
Peak Detect acquisition intervals (1250)
• = Sample points displayed
Peak Detect mode displays the highest and lowest acquired voltage in each
interval.
NOTE. If you set the horizontal scale (seconds/division) setting to 2.5 ms/div or
faster, the acquisition mode changes to Sample because the sample rate is fast
enough that Peak Detect is not necessary. The oscilloscope does not display a
message to tell you that the mode was changed to Sample.
