Start Time
(
Waveform only
) Sets the start time of the waveform
measurement (default: 0s, minimum: 0s, maximum: dynamic). In
Waveform mode Setting the Start and stop time enables you to
display a subset of the data on the display in order to speed up the
refresh rate when the acquisition time is long. Changing the Start
Time changes which data point is displayed on the left side of the
screen.
Couplings: When the change of Stop Time makes time domain
display length exceed the limitation, the Start Time will change to
satisfy time domain display length limitation:
——The maximum value is determined by current Sample Rate and
the maximum capture samples.
——Start Time is adjusted to the nearest sample point based on
the Sample Period.
——The maximum time domain display length is 524,288 points.
Time Domain Display Length [pts] = {[Sample
Rate[pts/s] x (Stop Time[s] - Start Time[s])] +
1}
Where:
pts = points
s = seconds
—
Stop Time
(Waveform only) Sets the stop time for the waveform
display (default: 100
μ
s, minimum: 0s, maximum: dynamic). In
Waveform mode Setting the Start and stop time enables you to
