Create Limit Test Template
Access this control window from the Mask menu and select Limit Test Setup….
Overview
You can specify vertical and horizontal tolerances,
create, and store the limit test templates.
To Use
Click the Source drop-down list to select the source
you want to use to create the template.
Note
You cannot use waveforms in FastAcq, wfmDB, FastFrame, roll or XY(Z) modes as a template
source or as an active mode during limit testing.
Click the Destination drop-down list to select the location for saving the template. Templates are
stored in Reference Waveforms Ref1–Ref4 (Ref1–Ref2, for 2-channel instruments) or File. If you
select File, you can choose the location for saving the template from the Save Reference
Waveform As dialog box.
Set tolerances by using the multipurpose knobs or the pop-up keypad.
Your template waveform will be smoother if you use Average acquisition mode to acquire it. Use
Envelope acquisition mode to create template waveforms that include occasional overshoots.
Behavior
The Vertical tolerance is adjustable using the upper multipurpose knob and Horizontal tolerance is
adjustable using the lower multipurpose knob. Adjustments are made in 20 m/div increments.
Tolerances set the amount the waveform can vary without violating the template.
The source you select is used to create the template. The Source drop-down list contains the
following choices: Ch1–Ch4, Math1–Math4, and Ref1–Ref4.
The Destination drop-down list contains the following choices: Ref1–Ref4 and File (only Ref1–
Ref2 are available on 2-channel instruments). Selecting File activates the Save Reference
Waveform As dialog when you click Save. Clicking Save when Ref1–Ref4 is selected saves the
template to the selected reference memory.
