User manual TEKTRONIX SDXUP DATASHEET

[. . . ] There are ready-to-use presets that allow you a head-start on your testing. Offline mode: SerialXpress applications can run on an external PC, thereby reducing the time taken to synthesize large waveforms and leaving the AWG free for continued testing. Features & Benefits Flexibility: Jitter generation has become so flexible that the user now has the freedom to try various permutations and combinations of jitter parameters like Pj, Rj, ISI, Noise, Delay, etc. Replicate scenarios: The signals are digitally synthesized. All AWG setups can be recalled and the scenarios can be replicated on any other AWG within seconds. [. . . ] A programmatic interface enables easy integration of SerialXpress into test automation systems. Advanced Pre/De-emphasis and Noise Many standards such as PCIe require the output waveform to be pre/de-emphasized. SerialXpress allows easy addition of pre/de-emphasis, including preshoot, with all other jitter parameters. Vertical noise can also be added at both near and far end of the channel. ISI Creation SerialXpress allows creation of ISI in two ways. First, the ISI value can be directly dialed-in. Second, an S-parameter file generated from a Tektronix sampling oscilloscope or a vector network analyzer can be directly convolved with the base pattern to recreate the channel characteristics. By applying inverse filtering the effects of the channel can be de-embedded from the system. Also, ISI within the S-parameter can be scaled upwards or downwards, which will alter the characteristics of the channel. Delay SerialXpress allows users to introduce delay to the waveform, and this feature can also generate skew between channels or patterns. Base Pattern SerialXpress is bundled with several sample patterns for various standards like SATA, Display Port, SAS, PCIe, HDMI, USB, MIPI, and Fibre Channel. Patterns can also be directly entered in a Binary, Symbol, or Hex editor or loaded as a file. Idle State*1 Standards like SATA call for OOB signaling which requires idle state followed by a burst. Now the user can directly create this idle state without the need of using additional power dividers. Noise and offset can also be added to these idle state waveforms. Idle state can also be defined as a part of pattern definition. Calibration SerialXpress has a built-in calibration routine which controls a Tektronix oscilloscope and calibrates the output of the AWG for periodic jitter and random jitter, reducing the need for time-consuming manual calibration. Bandwidth Expansion Filter Rise time of the AWG can be expanded further by applying the bandwidth expansion filter. For example, when used with AWG7122C and Option 06, this compensates for the DAC roll-off at higher frequencies and extends the bandwidth up to 9 GHz. *1 When idle state (z) is included in the pattern definition, no jitter is applied. Scrambling, PWM, 4-PAM, and 8b/10b Encoding The input data pattern can be scrambled by defining a polynomial.
