Automated Pass/Fail Testing

Validating signal quality is an important part of any embedded system
design. One way to determine how well your signals conform to expected
signal quality is to use mask testing. A mask de fines a portion, or portions,

A common method for understanding your signal quality is to compare
against a known good or “golden” waveform. You can apply horizontal and

used for quick, accurate Pass/Fail testing. This method is also a great way
to perform go/no-go testing on a manufacturing line by enabling repeatable,
fast decisions on the quality of a component or system. The Limit Test
Application Software allows you to save your limit test template for use later
across multiple oscilloscopes in a lab or on a production line.

Option MTH, MTM – Mask Test Application Software

When it is necessary to measure performance of your signals against
telecommunications or computer standard s to verify compliance and
interoperability, the Mask Test Application Software, with more than 100
standard masks, makes it easy. Each standard mask is easily loaded
from the oscilloscope internal memory and can be immediately used to
conduct P

ass/Fail testing. Adherence to a standard mask is determined

pixel-by-pixel throughout the display.

When a sta

ndard mask is loaded, the oscilloscope makes use of the
integrated Communication Trigger. Each standard mask is associated
with a communication standard and the m ask you select automatically
determines which communication trigger is used. Some models include
integrated clock recovery circuitry up to 6 Gb/s for NRZ eye patterns. Clock
recovery allows you to perform more reliable and accurate ma sk testing.

The oscilloscope can reduce setup time for making a mask test
measurement by performing an Autoset for vertical, horizontal, and trigger

ers on the source signal. Additionally, to reduce the chance of

paramet
failures, the oscilloscope can Autofit the waveform to the mask to minimize
hits within the m ask. It can do this a single time following an Autoset or it
can perform an Autofit after every triggered acquisition.

The Mask Test Application Software provides flexible test definitions
enabling you to tailor the test to your needs. You can run a test for a
user-defined number of waveforms (up to 2.14×10

9

). The Repeat Test

and Pretest Delay capability enables swapping of test locations before

ding with a test over multiple cycles of the test. You can set the

procee
number of violations that can occur before a test status is considered failed.
The oscilloscope can also perform a number of actions when a test fails or
completes. Actions the oscilloscope can perform when a test fails include
stopping the acquisition, e-mailing a message indicating the test has failed,

The Mask Test Application Software enables multiple actions upon a test failure or the
completion of a test, tailoring the test to your specific needs.

number of hits within the mask. A secondary display shows the total number
of hits in each segment of the mask providing further insight into any mask
