Operator's Manual
92 WS-OM-E Rev B
For any parameter that computes on every event, the value displayed is equal to the number of
events per acquired waveform. If x waveforms were acquired, the value represents x times the
number of cycles per waveform. Also, the "value" is equal to the measurement of the last cycle on
the last acquisition.
Statistics continue to accumulate with each additional trigger until Clear Sweeps (either on the
front panel or in the Measure menu) is activated, or a control (Volts/div, for example) is changed.
Measure Gate
Using Measure Gate, you can narrow the span of the waveform on which to perform parameter
measurements, allowing you to focus on the area of greatest interest. One gate serves all
parameters; i.e., there is not a separate gate for each parameter.
You have the option of dragging the gate posts horizontally along the waveform, or specifying a
position down to hundredths of a division. The default starting positions of the gate posts are 0 div
and 10 div, which coincide with the left and right ends of the grid. The gate, therefore, initially
encloses the entire waveform.
In this example, you can see that the Measure Gate includes only five rising edges. Therefore,
parameter calculations for rise time are performed only on the five pulses bounded by the gate
posts. The position of the gate posts is shown in the Start and Stop fields in the accompanying
dialog.
