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.
Touch Gate in the measure dialog box, 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:

19.1 Overview
The T3DSO2000A supports 2 math traces and multiple operators: Addition (+),
subtraction (-), multiplication (x), division (/), differential (d/dt), integral (∫dt), square root
(√), FFT, average and ERES, as well as a formula editor. The math traces are labeled
with an "F1" and "F2" icon and can be measured by the cursors or as the source of auto
measurement.
Press the MATH button on the front panel, or touch + in the channel descriptor box region
and select Func1 or Func2, and then the math dialog box pops up.
