You can click on the corrosponding button to choose among the different modes
of Periodic Jitter 2. The green LED on the button indicates the currently selected
mode of Periodic Jitter 2.
The ability of sweeping the PJ settings supports testing DUTs according to the
PCIe 2.0 and PCIe 3.0 standard without the need of providing a jitter modulation
signal externally.
Periodic Jitter 2 – Constant Jitter Parameters
The Periodic Jitter 2 – Constant Jitter is characterized by:
• Amplitude
• Frequency
• Waveform
N O T E
You will not see the parameter (Amplitude and Frequency) in case the PJ Sweep is
enabled.
N O T E
The setting for the jitter Amplitude is shared with the Constant Amplitude Sweep
mode.
A graph indicates whether the chosen setting of frequency and amplitude is
tolerable.
