But your dBER distribution may also look like this:
The measurement will calculate the Level and Standard Deviation
results from all data points. The marker allows you to measure the
μ
(Mu) and
σ
(Sigma) of the individual peaks.
DUT Output Timing/Jitter
DUT Output Timing/Jitter - Concepts
This type of measurement is used to measure the timing and jitter
behavior for a device under test (DUT). It uses a bit error rate (BER)
measurement to evaluate the shape of the eye for the output signal of
the DUT. It also analyzes the jitter, separates the random jitter and
deterministic jitter components, and estimates the total jitter.
A direct result is the determination of the optimum sampling point delay
for receiving data from the DUT with maximum confidence.
DUT Output Timing/Jitter includes the Fast Total Jitter measurement
that can be used to measure the total jitter for devices which generate
a very low error density in a reasonable time span.
