Purpose:

controls the sampling behaviour of the oscilloscope

Slow Sampling Transition

In normal (fast) sampling mode, PicoScope collects enough data to fill the screen and

then redraws the whole view at once. This method is suitable for fast timebases, when

the screen is redrawn many times each second, but with slow timebases it can cause a

unacceptable delay before the data appears on the screen. To avoid this delay,

PicoScope automatically switches to slow sampling mode, in which the scope trace

advances gradually across the screen as the scope captures data.

The Collection Time control lets you select the timebase at which PicoScope switches

to slow sampling mode.

Slow Sampling Display

When this box is checked, PicoScope displays the previous waveform in the buffer

while gradually redrawing the new waveform over the top of it. Thus, at any time, the

left-hand side of the view shows the beginning of the new waveform, while the right-

hand side shows the end of the previous waveform. A vertical bar separates the two

waveforms.
