Limit-Mask Testing (Optional)
A common task during the development process is character-
izing the behavior of certain signals in a system. One method,
called limit testing, is to compare a tested signal to a known
good or “golden” version of the same signal with user-defined
vertical and horizontal tolerances. Another common method,
called mask testing, is to compare a tested signal to a mask,
looking for where a signal under test violates the mask. The
MDO4000C Series offers both limit and mask testing capability
useful for long-term signal monitoring, characterizing signals
during design, or testing on a production line. A robust set of
telecommunications and computer standards are provided to
test for compliance to a standard. Additionally, custom masks
can be created and used for characterizing signals. Tailor a
test to your specific requirements by defining test duration in
number of waveforms or time, a violation threshold that must
be met before considering a test a failure, counting hits along
with statistical information, and actions upon violations, test
failure, and test complete. Whether specifying a mask from
a known good signal or from a custom or standard mask,
conducting pass/fail tests in search of waveform anomalies
such as glitches has never been easier. The optional limit/
mask test functionality is offered free for a 30-day trial period.
This free trial period starts automatically when the instrument
is powered on for the first time.

2. Spectrum Analyzer (Optional)
Fast and Accurate Spectral Analysis
When using the optional spectrum analyzer input by itself, the
MDO4000C Series display becomes a full-screen Frequency
Domain view.
Key spectral parameters such as Center Frequency, Span,
Reference Level, and Resolution Bandwidth are all adjusted
quickly and easily using the dedicated front-panel menus
and keypad.

Intelligent Ecient Markers
In a traditional spectrum analyzer, it can be a very tedious
task to turn on and place enough markers to identify all your
peaks of interest. The MDO4000C Series makes this process
far more efficient by automatically placing markers on peaks
that indicate both the frequency and the amplitude of each
peak. You can adjust the criteria that the oscilloscope uses to
automatically find the peaks.
The highest amplitude peak is referred to as the reference
marker and is shown in red. Marker readouts can be switched
between Absolute and Delta readouts. When Delta is selected,
marker readouts show each peak’s delta frequency and delta
amplitude from the reference marker.
