• Jitter Edge

When the measurement item is "TIE"　or "Cycle to Cycle", you need to set the

edge of the measurement signal. The edges include Rising, Falling, and Either.

Press Slope, then rotate the multifunction knob to select the desired edge,

and then press down the knob to select it. You can also press Slope continuously

or enable the touch screen to select it.

• Jitter Trend Graph

The trend graph can display the trend of the jitter measurement results. The data

obtained from the waveforms of the same frame are generated to form a curve,

which enables users to find out the cause for jitter.

Press

Trend continuously to enable or disable the display of the trend graph.

NOTE

When the clock recovery method is set to "PLL", the PLL system cannot reach the

expected ideal clock frequency until it reaches the specified lock time. During the lock

time, the TIE jitter measurement results based on the ideal recovery clock are incorrect.

The data produced during this time will be discarded in data processing. Therefore, in the

TIE jitter trend graph based on the PLL recovery, part of trend graph at the left section of

the screen will be lost. When a message "Invalid settings" is displayed below the trend

graph, please modify the loop bandwidth, the horizontal timebase, or other related

settings to make valid measurements.

•

Jitter Histogram

The histogram shows the distribution of the jitter measurement results. Gaussian

distributions indicates random jitter, and non-Gaussian distributions indicate the

deterministic jitter.

Press

Histogram continuously to enable or disable the display of the histogram.
