18.9 Gate
Sometimes the user may want to measure parameters for a certain specified time range of the signal
and ignore signal parts that lie outside of that range. In this case, the Gate function can be helpful.
Turn on the Gate , then two horizontal cursors A and B will appear
in the grid area. The gate setting dialog box will be displayed on the
right.
Gate cursors A and B are used to define the range of time for
parameter measurements. The oscilloscope only measures the
parameters of the data between A and B, ignoring the data outside the
range.
The setting of gate cursors is similar to that of ordinary cursors. See
"Select and Move Cursors" for details.
The figure below shows a scenario in which the gate function is used to measure the peak-peak
parameter of the trough of an amplitude modulated waveform:
