Acquisition Modes
The InfiniiVision oscilloscopes have the following acquisition modes:
•Normal — for most waveforms (with normal decimating at slower sweep speeds, no
averaging).
• Peak Detect — for displaying narrow pulses that occur infrequently (at slower sweep
speeds).
• Averaging — for reducing noise and increasing resolution (at all sweep speeds,
without bandwidth or rise time degradation).
• High Resolution — for reducing random noise (at slower sweep speeds).
Realtime sampling (where the oscilloscope produces the waveform display from samples
collected during one trigger event) can be turned off or on in the Normal, Peak Detect,
and High Resolution modes.
(For information on the XY horizontal mode see “XY Horizontal Mode” on page 220.)
At Slower Sweep Speeds
At slower sweep speeds, the sample rate drops because the acquisition time increases
and the oscilloscope’s digitizer is sampling faster than is required to fill memory.
For example, suppose an oscilloscope’s digitizer has a sample period of 1 ns (maximum
sample rate of 1 GSa/s) and a 1 M memory depth. At that rate, memory is filled in 1 ms. If
the acquisition time is 100 ms (10 ms/div), only 1 of every 100 samples is needed to fill
memory.
Selecting the Acquisition mode
To select the acquisition mode press the [Acquire] key on the front panel.
Normal Mode
In Normal mode at slower sweep speeds, extra samples are decimated (in other words,
some are thrown away). This mode yields the best display for most waveforms.
