Sample Period Display (Timing only)

The sample period display only appears in a timing analyzer.  A sample
period is the interval of time between new data samples.  Every time a new
measurement is taken, the analyzer updates the display.

The Current Sample period display is the sample period used for the last
acquisition.  The Next Sample period is the new sample period to be used at
the next acquisition.  If the acquisition mode is set to automatic, changing the
sec/Div or delay will affect the sample period.
