Acquisition Control

Normal Acquisition Mode

In Normal mode at slower time/div settings, extra samples are decimated
(in other words, some are thrown away). This mode yields the best display
for most waveforms.

Peak Detect Acquisition Mode

In Peak Detect mode at slower time/div settings, minimum and maximum
samples are kept in order to capture infrequent and narrow events (at the
expense of exaggerating any noise). This mode displays all pulses that are
at least as wide as the sample period.
For InfiniiVision 3000 X- Series oscilloscopes, which have a maximum
sample rate of 4 GSa/s, a sample is taken every 250 ps (sample period).

• Normal — at slower time/div settings, normal decimation occurs, and
there is no averaging. Use this mode for most waveforms. See
"Normal Acquisition Mode"
• Peak Detect — at slower time/div settings, the maximum and minimum
samples in the effective sample period are stored. Use this mode for
displaying narrow pulses that occur infrequently. See

Averaging — at all time/div settings, the specified number of triggers

are averaged together. Use this mode for reducing noise and
increasing resolution of periodic signals without bandwidth or rise
time degradation. See
High Resolution — at slower time/div settings, all samples in the
•
effective sample period are averaged and the average value is stored.
Use this mode for reducing random noise. See
