Store the momentary waveform
and display it permanently for
reference. The display also shows
the actual waveform.
To recall a saved waveform from memory and use it as a
reference waveform, refer also to Chapter 5 Recalling
Screens with Associated Setups.
Example of reference waveform with an additional
envelope of
± 2 pixels:
black pixels: basic waveform
gray pixels: ± 2 pixels envelope
1 vertical pixel on the display is 0.04 x range/div
1 horizontal pixel on the display is 0.0333 x range/div.
Pass - Fail Testing
You can use a reference waveform as a test template for
the actual waveform. If at least one sample of a waveform
is outside the test template, the failed or passed scope
screen will be stored. Up to 100 screens can be stored. If
the memory is full, the first screen will be deleted in favor
of the new screen to be stored.
The most appropriate reference waveform for the
Pass-Fail test is a waveform envelope.
To use the Pass - Fail function using a waveform
envelope, do the following:
1 Display a reference waveform as described in the
previous section “Comparing Waveforms”
2
ENTER
From the Pass Fail Testing: menu
select
Store “Fail” : each scope screen
with samples outside the reference
will be stored
Store “Pass” : each scope screen
with no samples outside the
reference will be stored
Each time a scope screen is stored you will hear a beep.
Chapter 3 provides information on how to analyze the
stored screens.
