Fluke 192B - 196B/C - 199B/C Users Manual 7 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 6 Recalling Screens with Associated Setups. Example of reference waveform with an additional envelope of ±2 pixels: black pixels: gray pixels: basic waveform ± 2 pixels envelope 1 vertical pixel on the display is 0.04 x range/div 1 horizontal pixel on the display is 0.0375 x range/div 24 Pass - Fail Testing (C versions only) 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 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 4 provides information on how to analyze the stored screens.

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 6 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 0.0375 x range/div
Pass - Fail Testing (C versions only)
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
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 4 provides information on how to analyze the
stored screens.
