Limit Testing
(not available on TDS1000C-EDU models)
You want to use the oscilloscope to monitor an active input signal against a
template and to output pass or fail results by judging whether the input signal
is within the
bounds of the template.
1. Push the front-panel Utility button.
2. Select Limit Test from the resulting side menu to bring up the limit testing
menu.
3. Select Source from the side menu to define the source of the waveform to
compare against the limit test template.
4. Select Compare To to specify the limit test template against which to
compare test signals sectioned with the Source menu item.
5. Push Template Setup from the side menu to define the boundary to compare
with the input source signals. You can create the template from internal or
extern
al waveforms with specific horizontal and vertical tolerances. You can
also create them from previously saved template settings.
On the
resulting side menu,
Push Source to se t the location of the signal source used to create the limit
test
template.
Push V Limit and turn the multipurpose knob to set the vertical limitation
val
ue, in vertical divisions, by which you can vary the source waveform
vertically when you create the test template.
Pus
h H Limit and turn the multipurpose knob to s et the horizontal limitation
value, in horizontal divisions, by which you can vary the source waveform
horizontally when you create the test template.
Push Apply Template to store the template waveform to the reference channel
selected in the Destination menu.
Push Destination to set the location of the reference memory location used to
store the limit test template.
Push Display Template and toggle between On and Off to display or not a
stored template.
6. Push the Action on Violation button and select an action from the resulting
menu to describe what the o scilloscope will do after it detects a violation. You
can select between Save Waveform and Save Image.
7. Push the Stop After button and toggle the resulting button with the same
name to define the conditions that will stop limit testing. Select Waveforms,
Violations,orTime and use the multipurpose knob to set the desired number
