6. Touch inside the Math Operator field and select P Script from the Select
Measurement menu.
7. In the "Script Math" dialog, touch inside the Script Language field and select either
VBScript or JScript from the pop-up menu.
8. Touch the Edit Code button; the Script Editor window opens. You can enter code in this
window or call up an existing script from a file storage location. If you create your script in
this window, you can then export it and save it to file.
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. 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.
Note: If you have Grid On Top enabled, you will not see the gate posts in their default position at each end of the grid. But if
you touch either end of the grid, a drag cursor will appear, indicating that you have control of the post and can now
drag it.
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.
