12 Acquisition Control

• Normal — at slower time/div settings, normal decimation occurs, and

there is no averaging. Use this mode for most waveforms. See

"Normal Acquisition Mode" on page 194.

• 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 "Peak Detect

Acquisition Mode" on page 194.

• 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 "Averaging Acquisition Mode" on page 197.

• 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 "High Resolution

Acquisition Mode" on page 199.

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).
