2. Ensure that the side button corresponding to the desired action reads ON.
 If you want to send a hardcopy command when waveform data exceeds
the limits set, toggle Hardcopy if Condition Met (side) to ON. You can
set the hardcopy system to send the hardcopy to the file system. (Do not
forget to set up the hardcopy system. See Hardcopy on page 3–164 for
details.)
 If you want the bell to ring when waveform data exceeds the limits set,
toggle Ring Bell if Condition Met (side) to ON.
 If you want the oscilloscope to stop when waveform data exceeds the
limits set, toggle Stop After Limit Test Condition Met (side) to ON.
NOTE. The button labeled Stop After Limit Test Condition Met corresponds to the
Limit Test Condition Met menu item in the Stop After main menu. You can turn
this button on in the Limit Test Setup menu, but you cannot turn it off. To turn it
off, press Stop After and specify one of the other choices in the Stop After side
menu.
3. Ensure that Limit Test (side) reads ON. If it reads OFF, press Limit Test
(side) once to toggle it to ON.
When you set Limit Test to ON, the oscilloscope compares incoming
waveforms against the waveform template stored in reference memory
according to the settings in the Limit Test Sources side menu.
You can compare a single waveform against a single template. When making a
single waveform versus a single template comparison, consider the following
operating characteristics:
 The waveform will be repositioned horizontally to move the first sample in
the waveform record that is outside of template limits to center screen.
 The position of the waveform template will track that of the waveform.
