Measuring Waveforms Automatically
3–72
TLS 216 User Manual
Measurements (side). Select your measurement based on its position in the
readout. (See the following NOTE.)
NOTE . As you create measurements, they are displayed in the order created.
Measurement 1 is the top readout, Measurement 2 is below it, and so on. (See
Figure 3-31 on page 3–68.) Once you display a measurement readout, it stays in
its position. It does not move upwards when you remove any readouts above it.
To limit all automated measurements to a specific part of the waveform record,
do the following steps:
1. Press MEASURE
➞
Gating (main)
➞
Gate with V Bar Cursors (side).
(See Figure 3-33.)
Turning gating on turns on the V Bar cursors. These cursors now define the
section of the waveform you want the logic scope to measure. This section is
called the gated region.

2. Using the general purpose knob, move the selected (the active) cursor. Press
SELECT to change which cursor is active. Adjust the cursors until they just
span the measurement area.
Turn on Gating
