Wander Compensation The time-base Wander Compensation checkbox enables or disables the Time Base Wander Correction for a measurement. Small variations in the DSO internal reference time base appear as low-frequency jitter (wander) in the acquired signal. For mask tests and edge jitter measurements, the DSO analyzes the acquired samples and removes the effect of the temporal drift (wander). - Page 15 The version for this software can be found after selecting the “About Us” under “help” menu option. Then, the following information will be displayed: Zooming can be done by clicking on the graph and dragging, which would draw a dotted window.

Oscilloscope Measurements While capturing the eye, a user can perform measurements by simply clicking the corresponding buttons: Top, Base, Min, Max, Fall time, Rise time, Peak to Peak, Eye Amplitude, Eye Height, Eye Width, Jitter, and the crossing percentage. The Check All text box can be selected to capture all the measurements in one action. - Page 20 Measurements Measurement Screenshot Description The X and Y histograms show the density Histogram distribution of the samples along the x and y axes: The average y-value of the high-to-high transitions.

- Page 23 The Deterministic Jitter value is displayed in DJ & RJ picoseconds and the Random Jitter value is displayed in fs. The Switch to Mask Mode button, located between the Eye and Pattern buttons, is used to find the maximum mask margin that results in no more than a specified number or ratio of failing points.

The Extinction Ration is defined as the ratio of the power levels of the ‘1’ and the ‘0’ logic Extinction Ratio levels of an NRZ signal. As it is a ratio of two powers, it is depicted in dB. Transmitter and dispersion eye closure (TDEC) is a measure in dB of an NRZ optical transmitter’s vertical eye closure as if observed at the end of a worst-case fiber. - Page 28 Figure 10: PAM4 pattern mode Current List of Supported Filters: Moving Average Filter for signal smoothing: User can specify window size. Order Bessel Thomson filter at frequency equal to 0.75 of the bit rate (order and cutoff are configurable). CTLE filter: User can automatically or manually select the filter parameters. Adaptive CTLE can determine the CTLE for best Eye Height.

S Parameter Mode The MultiLane DSO is now capable of measuring insertion loss S-parameters. Depending on how the DSO is connected, the user should be able to measure either of S21 dd, S12 dd, S21, S12, S43, S34, etc. The only difference between all the above is: 1. - Page 31 Two through connectors that can mate the cable pairs together.

Page 40: Appendix V: Preserve Noise Feature
Appendix V: Preserve Noise Feature Figure 22: Effect of "Preserve Noise" feature In order to accurately represent noise in a DUT waveform, a sufficient number of samples must be acquired per symbol. In this case, when higher resolution is attained, noise can be more accurately re-injected into the DUT waveform. - Page 41 North America Worldwide Asia 48521 Warm Springs Blvd. Suite 310 Houmal Technology Park 14F-5/ Rm.5, 14F., No 295 Fremont, CA 94539 Askarieh Main Road Sec.2, Guangfu Rd.
