Timebase
— The ProbeScope’s timebase is its sam-
pling rate (the rate at which measurements are taken)
and is not always the same as used in typical oscillo-
scopes.
• The timebase on the ProbeScope’s LCD repre-
sents the probe’s sampling rate and is shown in
seconds (such as 0.1 ms, meaning that the
ProbeScope takes a measurement every 0.1 ms).
• The timebase on the computer’s display depends
on whether or not you select the grid overlay to
appear on the oscilloscope’s display.
– When the grid is not displayed, the timebase
on the computer’s display shows the Probe-
Scope’s sampling rate (matches the timebase
shown on the ProbeScope’s LCD).
– When the grid is shown, the timebase on the
computer’s display is 10 times the LCD’s sam-
pling rate and is shown in seconds per grid di-
vision (the same as in typical oscilloscopes).
